Scary’um Aquarium

My favorite aquarium or zoo, though small, is the South Carolina Aquarium. It showcases the native animals found in the state starting in the upstate mountains all the way down to the deep ocean.  While at other aquariums you get to view exotic species you probably won’t see in your lifetime, the South Carolina Aquarium is essentially a living guidebook to the state’s flora and fauna! Not to mention, they have a touch tank!

For the month of October, the aquarium has taken on a Halloween theme called Scary’um Aquarium. It was worth the short walk through the haunted aquarium section just to see my husband jump!

I think the little slider is contemplating the solar reflection quality of the plastic tombstone in his tank.

These Yellow Rat snakes (Elaphe obsoleta) seem to be reacting to the change in temperature outside, even though they have a nice enclosure inside. The color pattern of these two is found along the Southeastern coast.

Another reptile hanging out in the aquarium, I think this fellow is the Canebrake or Timber Rattlesnake.

We caught a feeding show in the Great Ocean Tank. They have several different methods that they use to make sure the fish are fed properly and all the work is done by scuba-diving volunteers.

I mentioned above that they showcase native animals and plants, but there is an exotic swimming around. It’s the Lionfish, an invader of our coastal waters that can cause a painful wound when encountered. These fish make nice aquarium additions, until they get too large and then their owners dump them in the ocean, their ‘home’.

But back to the natives, we had walked the beach at Fort Moultrie a few days before and found stranded Cannonball jellyfish. Oddly, still clinging to the drying jellies were young Spider Crabs. Lo and behold, they are in the aquarium, too! This fellow was holding on to a Sea Nettle.

While juveniles, these crabs hang on to jellies and either eat the scraps or, creepily, eat the jellies they ride on. Another curious habit they have when young and bottom-dwelling  is placing debris on their backs.  This fellow below has used some seawhip as camouflage.

And finally, the biggest treat of our visit was meeting Phoenix! She’s an American Kestrel that met an uninsulated powerline. While lucky to be found, she lost most of her talons and is incapable of catching prey.

We noticed her beak immediately and asked if it was due to her trauma, but as it turns out, Kestrels have irregular beaks with a sharp protrusion called a ‘tominal tooth’ to puncture the spinal cords of small animals. Another neat adaptation they have is the black spotting on the back of their heads said to resemble eyespots and fool would-be attackers. A very neat, attitude-filled bird!

Who Is Under Your Beach Towel

This blog has been hit many times by people looking for answers about the creatures they are sharing the beach with. I thought I should put together something more concise than my random posts to help out these curious folks, so here it is!     

Below you will find descriptions about common animals found on beaches near Charleston, SC.     


Probably the most ubiquitous and well-known animal at the beach is the seagull.  In South Carolina there are 5 species of gulls, with the Laughing and Herring Gulls as the most common during the summer months. They are opportunistic feeders and will scavenge anything they find on the beach, including dead fish and washed up jellyfish.  Some species have figured out how to open shells by dropping them on pavement or hard sand. The Laughing Gull, so named because of its comical call, has learned that a human with sandwich bags, coolers, or cracker boxes will probably drop crumbs, and therefore it is nearly impossible to eat on the beach without a squadron of screaming bird beaks announcing your culinary activities.

Brown Pelicans

Another prominent bird is the Brown Pelican. Although you won’t often see it next to your beach towel, this bird is often seen diving into water head first for a fish, gliding just above the waves, or flying in formation.  With a wingspan of 7 feet and an odd-looking pouch under its bill, this bird is unmistakable though the smallest in the pelican family.  Every morning, these birds must stretch their pouches to keep the skin flexible and tear resistant.    

A tricky bird spotted flying around the beach looks similar to a seagull, but dives in the water pelican-style.  Terns are numerous along the coast and can range from mockingbird-sized to seagull-sized. They are mostly white with a black head and very long, skinny wings.     



Though there are several dangerous jellies in the waters off South Carolina, the most common that washes up is the Cannonball Jelly. This harmless creature is planktonic, meaning it does not have much control over where it goes, but it does dive deeper during the night and come back to the surface during the day.  These jellyfish have a brown border on their bell and if you look closely, you can see the tiny ‘eye’ spots that detect light, direction, and scent molecules.  Their feeding organ is on the underside and they use it for catching plankton.  Many jellyfish serve as food for sea turtles.

There are many crabs that live at the beach, but the one most likely hiding under your beach towel is the terrestrial Ghost Crab.  These odd fellows spend their life running from the upper beach and sand dunes to the swash zone [where the sand is just wet] and back again. During the night they come out to feed on clams and spend the day in their burrows. Though they can breathe air, they must have wet gills to do so, that being the only reason they would enter the water.  Their holes are usually in dry sand, about an inch or so wide, and during the hotter days, are plugged up with loose sand.

There are many types of swimming crabs that often wash up on the beach. Most common is the Speckled Crab though you can also find Blue Crabs occasionally. These crabs have modified, canoe paddle-looking back legs called swimmerets.

Ocellated Lady Crab Carapace

Last but not least of the true crabs, the Hermit Crabs often make appearances near beach towels.  Three species, the Long-wristed, Flat-clawed, and Striped, live in shallow water and are often seen scuttling back to the surf as the tide is receding. These little guys are foragers, picking food out of the sand, and they can often be observed fighting with nearby neighbors over shells.  They have a abdomens that look more like stingers than crab tails.   

Flat-clawed Hermit

Although not a true crab, the Horseshoe Crab needs mentioning.  Typically bottom dwellers, these harmless crab-like creatures come ashore to lay eggs. Occasionally their molts [shed exoskeletons] will wash up or be found floating on the surface of the water. The females are typically much larger than the males. Males have a front claw shaped like a boxing glove that helps them hold on to the shell of the female during mating.

The Ghost Shrimp is an abundant, crab-like creature whose burrows are often the object of curiosity for many beachgoers. When the burrows are just near the swash zone, they will often bubble and spew while the Shrimp pumps water through its burrow system. The Shrimp make thousands of tiny holes in the sand, generally the only evidence that they are even there. They have one large, white claw used for defence and mantaining the burrow.

There are many snails found on South Carolina beaches. Their shells are collected for their beauty, but little thought is put into what these snails do under the sand. 

Most of the snail shells you’ll find are from carnivorous creatures that attack and eat other mollusks. A great example is the Moon Snail or Shark’s Eye.  Moon Snails are responsible for the little beveled holes you see in other shells, the ones that look like they were put there to make jewelry. The snail creates these by licking the shells with its specially adapted tongue, called a radula.

Another predatory snail is the Knobbed Whelk, with its left-handed [opens on the left] counterpart, the Lightning Whelk. These snails pry open bivalves with the sharp edge of their shell.

Alright, longest post ever.  I’ll start a Part Two as I think of more creatures.  Leave a comment if you’d like to see a specific one mentioned! Thanks!
