Top Five Creepiest Creatures


Top Five Creepiest Creatures

Here at the Aquarium, we have creepy, crawly, and spooky creatures of all shapes, sizes, and species. In honor of Halloween this Saturday, we made a definitive list of our official creepiest critters – tell us what you think, then be sure to come visit Saturday from 10 a.m. – 3  p.m. for our third annual Green Halloween where you can SEE them in person! 

5. Brutus, Eurasian Eagle Owl 



Eyes as big as half dollars and as yellow-orange as a harvest moon stare straight into yours, the intense gaze of the apex predator creeping into your soul…or at least that’s how some may feel. The long look a Eurasian Eagle Owl can give you is not one you’ll soon forget. These owls are native to Europe and Asia, and are among the biggest in the entire world – they can reportedly boast a six-and-a-half-foot wingspan! Within this impressive wingspan are serrated (like the teeth on a knife) wing feathers that enable the owl to glide almost silently through the night, stalking its prey – unbeknownst – from the sky. Eurasian Eagle Owls hunt using their silent flight, keen eyesight, and impeccable hearing. Brown says that like other species of owl, eagle owls have facial disks, or groups of feathers around their ears, that actually direct sounds toward their ears. Owls can raise these feathers slightly when on the hunt, enabling them to hear the rustle of a mouse in the grass, the flapping of feathers in the night, or the slithering of a snake in a tree branch. These sounds give away the location of prey animals, making it easy for these owls to swiftly swoop in to catch a meal – and their pointed, powerful talons can exert 500 pounds of PSI (pressure per inch)! Compared to the human hand’s 30 lbs of PSI, that’s scarily strong. The scariest thing about this creature, however, is its history. During the first half of the 20thcentury, Eurasian Eagle Owl numbers declined radically as humans over-hunted and nearly poisoned the whole population. Local European governments began increasing protective measures regarding the owls, and they are now back to a healthier number, though not as populous as they once were. TSA’s resident Eurasian Eagle Owl, Brutus, will be one featured creature you can meet at Green Halloween this Saturday!

4. Lionfish 



This invasive species not only looks scary, with its tiger-striped coloring and venomous spines, but the fact that it has been introduced into nonnative habitats where it has no natural predators is truly terrifying. Thought to have been dumped by hobby aquarists into Florida waters in the mid to late 80s, lionfish have spread like a disease and can now be found as far south as South America. The problem lies in that they feed on coral reef fish and similar coral-supporting species. With no natural predators, their numbers are increasing too rapidly to replenish the species they feed on. Scientists have been keeping tabs on the alien fish and trying to track how their influence is affecting marine ecosystems and it comes as no surprise that the end results don’t look good.  Fortunately, many U.S. states encourage lionfish hunting and ridding them of your local waters. An added bonus: If you are well versed in cooking venomous fish, rejoice, because lionfish are considered to be quite tasty!

3. Julius Squeezer, Red-tailed Boa Constrictor 

One of the most storied and legendary creepy critters to ever slither is the snake! Feel squeamish? You’re so not alone. From their cold, scaly skin, to their forked tongues and tendency to eat rodents in one gulp, it’s no wonder these reptiles have secured legendary creep out status. Boa Constrictors are scary in part due to their large size and the way in which they sometimes kill prey – by coiling around it and squeezing so tight as to suffocate it. However, more often, they will strike their prey first, and then coil around it, causing it to die by cardiac arrest. Their jaws are lined with small, hooked teeth perfect for grabbing and holding prey while they squeeze around it. Very large, strong boas can cause spinal fracture due to the huge of amounts of pressure they can apply to prey. Boas will eat almost anything they can catch, be it birds, rabbits, monkeys – even wild pigs, their jaws stretch extremely wide, enabling them to swallow large prey whole. Being native to the warm, tropical climes of North, Central, and South America, boas like to dwell in humid places and partially enclosed spaces like hollow logs; news stories depicting an elderly couple in Florida who discovered a slithery surprise in their garage one day are not at all uncommon. Squeezer Slither

2. Great White Shark

With row upon row of razor sharp serrated teeth designed to shred and rip through flesh, along with the fact that they can grow to be 20 feet in length and weigh around 5,000 pounds, it’s no wonder many humans have a fear of the great white shark. While pop culture and movies like JAWS and Sharknado do nothing to dispel these fears, the fact remains that the great white shark is a scarily effective predator. Using the countershading of its body, its ability to pinpoint prey, and super speedy swimming skills, the great white was born to be an apex predator. Unfortunately, these attributes don’t stop it from becoming bycatch in the unsustainable fishing trade, or finned for soup in Asia. Much is still unknown about these misunderstood creatures, such as their mating and breeding habits, and their migratory patterns. Scientists like those from our own Harte Research Institute and members of OCEARCH, a research and expedition team who tag sharks and other apex predators around the world. The Aquarium’s newest exhibit, Saving Sharks, incorporates research from OCEARCH and HRI regarding shark conservation, because the scariest thing about great whites is how quickly they’re disappearing from our world’s oceans.

And, finally, drumroll please: the most terrifying, horrific, scream-inducing, bloodcurdling animal out there? Go take a look in the mirror. That’s right, it’s the human being. Though it’s the most intelligent creature in the world, this animal has a penchant for overpopulating, overusing (and abusing) the earth’s natural resources, and even littering the only home they have. They’re not all bad, though. They’ve created cures for diseases, they have extremely advanced technology, and many are humanitarians who try and help other animals and causes they find deserving. If more of them begin to treat the earth and their fellow animals with more respect, they’ll definitely take a dive down the creepiest creature list, but until then; they’ve got some work to do.  

Don’t fear the fin: Saving Sharks exhibit shows misunderstood fish need our help, not our fear


Justifying not only the existence, but the conservation of Jaws is a hard license plate to swallow for many ocean-loving humans. Not everyone feels pity for the ocean’s apex predators, but the fact is that sharks are crucial to the health of our world’s oceans and their declining populations need our help now more than ever. Helping to illustrate the various ways in which we can and are conserving shark species is Saving Sharks, the newest exhibit brought to you by thUntitled-1-01e Texas State Aquarium, OCEARCH, the Houston Museum of Natural Science, and the Harte Research Institute for Gulf of Mexico Studies at Texas A&M University-Corpus Christi.

Due to unsustainable fishing practices, habitat alteration, climate change, and finning, shark populations have declined between 70 and 90 percent in recent years, leaving many of them swimming toward the endangered species list. Humans, unfortunately, have had a heavy hand in getting them there. The good news is, we can help turn their grim fate around. Passing on all shark products, consuming only sustainable fish, fishing responsibly, and learning more about your local shark populations are all things you can do to make the oceans safer for sharks – which makes it safer for us all.

Saving Sharks aims to support these conservation practices by furthering learning about these often misunderstood predators using facts and educational efforts to combat such ideologies. A section on shark biology helps accomplish this by exhibiting a shark’s cartilaginous skeleton, as well as skin, scales, and teeth samples from a number of different species.

ToothlessDesigned to capture the hearts and minds of would-be conservationists and lifelong shark fans, alike, Saving Sharks is a fun, interactive, and informative exhibit. Featuring a live touch tank area where visitors can see and feel whitespotted bamboo, horn, and epaulette sharks, track great whites in real time, and even stand inside a life-sized underwater diving cage, it’s a shark showcase that’s sure to excite and engage every member of the family!

The king of the shark world, the great white, is well represented throughout the exhibit, especially where OCEARCH is concerned. OCEARCH is a non-profit organization and leader in open source data collection and research concerning great whites and other apex predators.

Aboard the OCEARCH research vessel, the team travels the world and collects data including reproductive conditions of females, body measurements for comparative studies around the world, muscle biopsies to identify key life stages, and more. Led by founding chairman and expedition leader Chris Fischer, OCEARCH is able to bring live shark tracking straight to your fingertips via the Internet and their Global Shark Tracker. Follow majestic creatures such as Katherine, the 14-foot great white who has swum over 15,000 miles in the two years since she was tagged, or cruise alongside Sam Houston, the 10-foot long tiger shark tagged off the coast of Port Aransas last summer. OCEARCH plays a critical role in providing scientific information necessary in tracking and measuring shark species across the globe, helping to lead and better steer conservation efforts. SandTigerSharks062515a

Some of the first identified sharks that OCEARCH ever tracked were tagged by Corpus Christi’s own Dr. Greg Stunz of the Harte Research Institute for Gulf of Mexico Studies at Texas A&M Corpus Christi. Stunz was one of the first grantees to benefit from the Texas State Aquarium’s Wildlife Care, Conservation, and Research Fund. Stunz’s main project focus was to gain a better understanding of shark migration patterns in the Gulf of Mexico. We’re excited that our funding could positively affect members of the local Corpus Christi community, both human and otherwise.

Take a dive into the underwater world of Saving Sharks this October and together, we can join fins and work to conserve these beautiful and fascinating fish!

Saving Sharks: A Great White Encounter


20030523a-dscn0132It’s either at the very top of your bucket list, or the number one thing you would never, ever dare to do: Swim with great white sharks.  

Here at the Texas State Aquarium, we’ve got some pretty brave souls. We have those who dive with the sand tiger sharks in our Islands of Steel exhibit; those who help give our 400-lb alligator Bo a physical, and even those work every day with our raptors, or birds of prey. But one of the bravest is Suraida Nanez-James, our manager of distance learning and outreach, who not only studied and helped to identify great whites; she cage dived with them, too.


Nanez-James is pictured wrestling bait back from a great white.

Back in the summer of 2003, Nanez-James was working on earning her undergraduate degree in Marine Fisheries at TAMUG and scored the opportunity to work for six weeks as a research intern for the now-defunct White Shark Trust Organization in Gansbaai, South Africa, A.K.A. the great white capital of the world.

Nanez-James and the rest of the crew were most interested in tracking demographic information of great whites in the area, i.e., recording data based on sex, length, and distinguishing marks.

“A big part of it was trying to get them to surface for us,” says Nanez-James, “Ideally, we were trying to study and ID their dorsal fins.” 20030606d-dscn0028

Research leader Michael Scholl called the process “finprinting,” and Nanez-James says it was a tad harder than it sounds.

After going about ten miles out in a rather pint-sized boat (cue Jaws quotes), their nine hour day began.

“We had to chum the water, and then drop bait, trying to get them close to the boat and to breach the water,” Nanez-James explains.

She said the task was made more difficult because the team didn’t want the sharks actually biting the buoys attached to the bait, or eating all of the bait. The object was not to feed the legendary creatures, but to lure them up to get photos for data purposes.

Nanez-James says it’s an experience she will never forget.

“I wasn’t scared of them, but let me tell you; it definitely gives you a healthy respect for them as predators. It was amazing to be able to get that close to them and just be aware of their grace and agility,” she says with awe. “Not only are they incredibly fast and agile for their size, they are super smart, too. They would learn where we were going to drop the bait and anticipate it before we even did it.”

A wealth of important information was recovered from the project, helping to support great white conservation efforts and also data in general.

“There’s just so much we don’t know about them – their migration patterns, where they breed, when and why they travel and why they travel so far,” Nanez-James says of the species.



Thanks to the efforts of scientists like Nanez-James and organizations like OCEARCH, Discovery’s Shark Week, and the shark tagging work done by Greg Stunz of the Harte Research Institute, we now know so much more and are learning every day about the wide world of sharks. Such research allows us to properly educate others about the oceans’ apex predators and also to learn how we can help conserve them for future generations and healthier oceans to come. 

Texas State Aquarium Saddened Loss of Fish Species


The Texas State Aquarium is saddened to report the loss of approximately 400 marine fish.  These fish inhabited several large habitats, including the Islands of Steel exhibit and the Flower Gardens exhibit. In an attempt to control a particularly difficult parasite that had proven resistant to other treatments, staff administered a different, commonly used drug. The fish in the affected exhibits had an adverse reaction to the medication. Staff members worked diligently throughout the night to save as much of the collection as possible, but considerable losses were sustained.

The majority of the Aquarium’s animal collection was not impacted. The Living Shores gallery, Nearshore gallery, Amazon, and Floating Phantoms, as well as a number of smaller exhibits, were not affected. None of the freshwater aquariums, and none of the touch tanks were impacted. In addition, none of the outdoor exhibits such as Tortuga Cay and Texas Trails were affected.  The loss represents about 13 percent of the Aquarium’s overall collection.

As a standard precaution, staff had tested the treatment on an individual smaller exhibit with no adverse reaction prior to administering it into the larger exhibit.

The Aquarium’s first priority is to focus on stabilizing the water in the affected exhibits. The Aquarium has sent water samples from affected exhibits to testing laboratories in hopes of a clear explanation for what caused the adverse reaction.

“This is a very sad day at the Texas State Aquarium,” remarked Aquarium Chief Marketing Officer Richard E. Glover, Jr. “We are working diligently to find out what caused the adverse reaction, and we will keep the public informed with any updates.”

Creepy Critter #3: Sand Tiger Shark


Creepy Critter #3: Sand Tiger Shark

Dun, dun. Dun, dun, dun, dun, dun, dun. DUN, DUN, DUN, DUN, DUUUUN! Though no Great White, if seeing the protrusive teeth of a Sand Tiger Shark doesn’t start the JAWS theme song playing in your head, something is wrong. TSA Omni3

These decidedly ferocious-looking beasts boast a mouthful of terrifying teeth that are even visible when their mouths are shut. They can go through thousands of teeth in a lifetime, losing up to hundreds per year. And even with all those teeth, this predator still swallows its food whole!

Most Sand Tiger Sharks range in size from 6.5 up to 10.5 feet and they can weigh anywhere from 200 lbs to 350 lbs. And despite their intimidating size, they eat little, and can go for extensive periods without feeding.



The stealth hunter gets its name from its tendency to reside near shoreline habitats, and they are often seen trolling the ocean floor in the surf zone, very close to shore. They are found in warm or temperate waters throughout the world’s oceans, except the eastern Pacific. 

Something that sets the Sand Tiger Shark apart from other carnivorous fish is its ability to self adjust its buoyancy levels. The shark will break the surface of the ocean, gulp air, and then store the air in its stomach, allowing it to float motionless in the water. All the better to silently stalk prey… Hans

Though this species of shark has relatively plentiful numbers, they have a scarily low reproduction rate and are thus listen as threatened on the worldwide species list, meaning they are vulnerable to endangerment in the future.

Visit Hans, our very own Sand Tiger Shark, at the Islands of Steel exhibit this Saturday for Green Halloween and learn more spooky shark facts!
