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.

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.

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.

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.

Nudibranchs are shelless mollusks. Aeolids are well known for their ability to feed on hydroid polyps, absorb the nematocysts without harm, and utilize them in their own defense. Shipments include species that feed on hydroid polyps. Florida Regal Goddess, Lettuce Nudibranch and Dorid nudibranch not included in assortments and must be order separately.

Aeolids feed on Aiptasia pallida anemone are helpful for home aquarists. Nudibranchs are shelless mollusks. Aeolids are well known for their ability to feed on hydroid polyps, absorb the nematocysts without harm, and utilize them in their own defense. Aeolid Nudibranchs are a suborder of Nudibranchia, the largest order in the subclass Opistobranchia (Ellis 2001). Nudibranch (pronounced Nudi-brank), means naked gills. Those organisms in the subclass Opistobrachia are hermaphroditic and have the atrium of the heart posterior to the ventricle (McDonald 1999). The order Nudibranchia is characterized by lack of shell, mantle cavity, operculum, and ctenidial gills in the adult form (McDonald 1999). There are four suborders of Nudibranchia: Doridoidea, Aeolidoidea, Dendronotoidea, and Arminoidea (Ellis 2001). Aeolids take their name from the Greek god of the winds, Aeolus because of the waving of their cerata resembles streamers in the wind (Tackett and Tackett 2003).

An interesting species of nudibranch. Green coloration with bumpy wart like surface. Availability is somewhat sporadic. Size: 4-8cm

It is a small octopus (perfect for small to medium aquaria) that inhabits empty mollusk shells, beer cans and bottles. It uses bits of gravel or shell as an operculum to close off the opening. Females brood elongated, amber eggs in the shell; and fully developed young octopuses may hatch out, ready to feed on minute crustaceans. Octopuses are considered to be the most intelligent of invertebrates. At night they steal out of their shells and pounce on fiddler crabs, or small hermits. Size: 5-7 cm. Females with eggs available March through June. Otherwise, available year round.
