Starfish, the Asteroidea, are the symbol of marine life. Every seashore has them, they live attached to rocks, or they crawl on the sand. They live up in the intertidal zone or out in the depth of the ocean.
E-1660 ORANGE STARFISH, Echinaster spinulosus
A handsome reddish-orange starfish with white spots. Exhibits several color phases within the species. Unlike the Atlantic Asterias, Echinaster is a well behaved, compatible member of the aquarium. Extending its eyecatching, vivid orange tubed feet, it propells iself gracefullly over the bottom and ascends the aquarium walls. It never burrows into the sand, and outlasts all other starfish. One of our most popular specimens.
Large $20.00 ( 8-10cm)
E-1665 SPINY SAND STAR, Luidia alternata
The Spiny Sand Star’s body is covered in small spines. This species is predatory toward other species of sea stars. Excellent for studying predator prey relationships and the roles of chemical signals between predator and prey. 10-14cm
E-1670 GRAY SAND STAR, Luidia clathrata
A large, flattened gray starfish that buries down into the sand. Using its highly modified, pointed tube feet, it glides over the bottom with great agility and relative speed, pouncing on sand dollars, brittlestars and small snails. Luidia is among the most primitive of all living starfish. Size: 10-14 cm.
E-1671 POINTED SAND STAR, Astropectin duplicatus
The Pointed Sand Star is a biological study of symmetry. It glides rapidly over the sand, raised up on its tubed feet feeding on minute gastropods. It hovers above a snail, drops its entire stomach out, engulfs it, and continues sliding along looking for more. With no anus, the mouth serves a dual purpose.
E-1672 ROYAL SEA STAR, Astropecten articulatus
E-1675 CHOCOLATE CHIP SEA STAR, Protoreastor nodosus
Brittlestars bear some resemblance to starfish; they have a small disc and long, lashing arms, as active as a tiny octopus. They have an interesting habit of snaking along, humping themselves up and slithering out of rocky crevices, which is why they are often referred to as serpent stars.
E-1690 SERPENT STAR, Ophioderma brevispinum. When darkness falls, these small
bodied long armed ophiuroids slip out from beneath the rocks or sea weed, and propel themselves forward, twisting and writhing like small octopuses. A piece of fish dropped in the aquarium sends them into a frenzy of lashing arms, as they wrap themselves around the food, writhing and heaving until its devoured. Guaranteed to catch the attention of even the most bored, uninterested student.
E-1700 HAIRY BRITTLESTAR, Ophiothrix angulata. This colorful banded brittlestar lives in sponges and tunicates, rhythmically waving its arms in the current. Feeding can be easily observed since the disc is soft and shows peristaltic movements. Some may exhibit luminescence. Ophiothrix has long spines covering its arms, giving it a hairy appearance. It has tremendous variation in color patterns. Size: 2-3 cm.
E-1701 BASKET STARFISH Astrophyton muriatum. This living “spanish moss” of
starfish is found in deep water attached to sponges and rocks. At night it expands its net of tentacles to catch plankton in the water. They come in a great array of colors ranging from reds, oranges, white and black.
