Like other hermit crabs, Clibanarius vittatus lives inside the empty shell of a gastropod mollusc.
As a hermit crab, it lives inside the empty shell of a gastropod mollusc and its soft abdomen and most of its limbs are normally hidden with just the dacryls, or claws, projecting.
Echinoderms form part of the diet of many organisms such as bony fish, sharks, eider ducks, gulls, crabs, gastropod molluscs, sea otters, Arctic foxes and humans.
Ulrich was a prolific writer, publishing numerous pamphlets on the subject of American paleontology, treating particularly the fossil Bryozoa, Gastropoda, Ostracoda, and Pelecypoda.
Many species of molluscs are indigenous to Nicaragua, including at least 79 species of terrestrial snails and slugs.
Samples of bottom fauna taken in 1998 documented the presence of nationally rare species of gastropods such as Hippeutis complanatus and bivalve Swan mussel; and during the preceding decades two species of limnetic gastropods were documented.
Two rare species of air-breathing land gastropods also live on the island, the two-lipped door snail Balea biplicata and the German hairy snail Pseudotrichia rubiginosa, as well as several rare species of beetles.
The rainbow star is a predator and feeds on a range of invertebrates including gastropod molluscs, limpets, bivalves, brachiopods, chitons, barnacles and tunicates.
Like other hermit crabs, P. prideaux has an asymmetric, unarmoured abdomen and protects this by concealing it within the empty shell of a gastropod of appropriate size and shape, and carrying it around by clasping onto an internal part of the columella of the sea snail shell.
He is perhaps best known for his publication with with Jean-Pierre Rocroi which laid out a new taxonomy of the entire class Gastropoda, published in 2005.

The bull ray feeds on various invertebrates including crabs, hermit crabs, squids, prawns, gastropod molluscs and bivalve molluscs.
The Winton Formation had a faunal assemblage including bivalves, gastropods, insects, the lungfish Metaceratodus, turtles, the crocodilian Isisfordia, pterosaurs, and several types of dinosaurs, such as the theropod Australovenator, the sauropod Wintonotitan, and unnamed ankylosaurians and hypsilophodonts.
Euomphalidae is an extinct family of Paleozoic marine molluscs which may be gastropods with anisostrophically coiled shells (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
These include bivalves and other molluscs, polychaete worms, amphipods and juvenile fish which hide among the leaf blades, sea urchins, crabs and caridean shrimps.
Demasterias imbricata (Asteroidea) and Aeolidia papillosa (Gastropoda) are two notably frequent predator species.
Vladimir Pešić is a scientist from Montenegro, a biologist who is an expert on Hydrachnidiae, the water mites, and a co-author taxon authority for a new species of freshwater snail Valvata montenegrina Glöer & Pešić, 2008 (Valvatidae, Gastropoda).
The Winton Formation had a faunal assemblage including bivalves, gastropods, insects, the lungfish Metaceratodus, turtles, the crocodilian Isisfordia, pterosaurs, and several types of dinosaurs, such as the theropod Australovenator, the sauropod Diamantinasaurus, and unnamed ankylosaurians and hypsilophodonts.
