Mollusca

The creeping foot, the unsegmented body and shell secreting mantle are brought to life in the mollusk. Spirals of the shell, created by mantle secretions fascinate the eye. Bivalves, clams, oysters and mussels sit peacefully on the bottom filtering single celled algae from the water, while ravaging whelks seek them out with predatory intent. With a drilling radula that would put a dentist’s drill to shame, boring snails rasp through the shells of other gastropods. Meanwhile, segmented chitons cling peacefully to rocks and shells, while ancient scaphopods dig their way down into the sand. With splendor of color and diversity of form, nudibranchs, snails without shells, glide by partaking of anemones and hydroids. Undulating gracefully, soft bodied sea hares that exude ink only when disturbed scrape green and red filamentous algae from the aquarium glass.


  • Included are chitons, clams, mussels, whelks, snails, and nudibranchs. When abundant, scaphopods and/or frilled sea hares may be included.

Since there are no fresh water echinoderms, this is one of the most popular phylogenetic assortments, with collections of writhing brittlestars lashing their snaky arms, bristling sea urchins and burrowing sand dollars. Sea cucumbers, shaped as their name implies, tunnel through the sediments like earthworms taking up nutrients and starfish creep up the aquarium glass, wrapping their arms around tunicates, or chopped clams. Sand stars emerge from sand and “speed” along the bottom, on raised tubed feet when a bit of food is dropped in the tank. These assortments usually include two or three of every listing, and sometimes there are surprises such as sea biscuits and other echinoderms.

The greatest diversity of fish form and function is found among marine species. Here the flat fishes, flounders, hog chokers, tonguefish, represent the epitomy of depression, and eels are the most elongate. Blowfish inflate themselves, and pipefish, looking like blades of grass, are perfect in camouflage. While these examples are likely to turn up in our fish assortment, there is no predicting the diversity and variety that will be provided. It is always a pleasant surprise.

$80.50

Grey triggerfish (Balistes capriscus) at Gulf Specimen Marine Lab and Aquarium.

Monacanthus hispidus

Their names come from their sandpapery skin, fishermen once used their hides to strike matches. Their dorsal spine has a trigger-like mechanism that makes it spring erect when they are threatened. Size: 4-8 cm.

$13.00$17.00

Gobiesox strumosus

Small fish shaped like a skillet; with a broad head and narrow body. The pelvic fins are actually a large, broad suction disc. Clingfish are usually found hiding in or on the shells around oyster bars and seagrass beds. Size: 4-6 cm.

Clingfish or skilletfish (Gobiesox strumosus)

Symphurus plagiusa

Small, flat, left-eyed fishes that taper to a point — “tongue-shaped” — hence the name. They are bottom-dwelling fish, common in the muddy bottoms of bays and estuaries feeding on small crustaceans and polychaete worms. Size 6-12 cm.

$20.00

Trinectes maculatus

This flatfish stays buried and looks like a baby flounder but seldom grows larger than six inches. Probably named from the days when hogs roamed the beaches and gobbled up fish as fast as seine fishermen dragged their catches up on the beaches. The scales, which make the fish stick to the deck, also could lodge in a hog’s throat. Very hardy and vigorous. Size: 6-12 cm.

$22.50

Hogchoker (Trinectes maculatus)

Paralichthys oblongus

Unlike the common gulf flounders, these flatfishes have four large, dark and round spots on their bodies.

$22.50

Four-spotted flounder (Paralichthys oblongus)

Paralichthys albigutta

Flounders belong to the group of fishes known as “flat fishes.” Their most unique feature is the placement of their eyes. As the young larvae develop, one eye migrates across the head toward the other. Depending on the species, flounders and other flatfishes are “right-eyed” or “left-eyed.” Lying flat on the sea bottom, flounders are masters of camouflage, changing their coloration to blend in with the substrate; hiding from predators or aggressively ambushing small fishes and crustaceans with their mighty tooth-studded jaws.

$21.50$34.50

Mugil cephalus.

Often seen jumping out of the water, mullet are the cows of the fish world, and are the main food fish of the northern Gulf Coast. They browse along the bottom, feeding on algae and tiny creatures that live in mud.

Lagodon rhomboides

It is the traditional large whelk used for dissection in invertebrate and general biology courses. Its ribbon of teeth scrapes away at other mollusk tissues, and it is excellent for demonstrating radular movements. It will quickly burrow down into the gravel, emerging to forage at night.

$17.50$41.50

A smaller form with a thinner shell, has a very long, well developed radula which is easily removed from its proboscis. Size: 6-12 cm.

$28.50

A small predatory snail that feeds on clams. The highly polished shell has a marbelized pattern of grey, brown, and white with distinct purple-brown spiral bands. Females will lay eggs in an aquarium in vase shaped horny capsules. Male is said to eject water, setting up vibrations, to attract a mate. Size: 5-7 cm.

$18.50

It has a larger, less colorful shell than F. hunteria and a bright purple foot. This species is useful for displaying fluke larvae, which can be produced almost 100 percent of the time by cracking the shell and soaking the animal in a dish of seawater. The common tulip feeds on small gastropods. Size: 10-14 cm.

$18.50

Despite its name is really a peaceful herbivore that cruises the night bottom. Its huge stalked eyes seem to peer up at you with an alarmed expression. When handled, it may go into a startling defensive behavior thrusting around with its small pointed foot, hence the name. Sporadically available. Size: 8 cm.

Often seen scouring the shells of larger whelks and horseshoe crabs. Turbo crawls up the walls of the aquarium, consuming algae like a vacuum cleaner, making pronounced tank clear and visible in a few days. Sporadic. Size: 1-3 cm.

$16.00

In a sand aquarium, they remain buried until a piece of fish is dropped in, and within minutes their siphons pop up like small periscopes and they converge on the meat. Nassarius will readily regenerate its tentacles, eyes, frontal lobe, operculum, foot and siphon. It has a long proboscis and moves by ciliary waves on foot. Preyed upon by tulip shells whose trails produce violent evasive action by Nassarius. Size: 1-1.5 cm.
