Jellyella Eburnea
''Jellyella'' is a genus of bryozoans in the family Membraniporidae. Etymology The genus is named in honour of the Eliza Catherine Jelly (1829–1914), of Cornwall, England in honour of her contributions to the study of bryozoans. Morphology ''Jellyella'' closely resemble ''Membranipora'', and in common with other members of the family Membraniporidae has twinned ancestrular zooids. However, ''Jellyella'' can be distinguished by the presence of intricately branched processes (called spinules) projecting into the zooidal chambers. ''Jellyella'' also have a calcitic skeletal ultrastructure made up of transversely arranged, elongate spindles. Ecology ''Jellyella'' is unusual in being a pseudoplanktonic bryozoan found encrusting floating objects, both natural and artificial. ''Jellyella eburnea'' is common on shells of the squid ''Spirula'' (which become detached from the soft body of the squid after death) and on the shells of the planktonic gastropod ''Janthina''.

Spirula
''Spirula spirula'' is a species of deep-water squid-like cephalopod mollusc, mollusk. It is the only extant taxon, extant member of the genus ''Spirula'', the Family (biology), family Spirulidae, and the order (biology), order Spirulida. Because of the shape of its internal shell, it is commonly known as the ram's horn squid or the little post horn squid. Because the live animal has a light-emitting organ, it is also sometimes known as the tail-light squid. Live specimens of this cephalopod are very rarely seen because it is a deep-ocean dweller. The small internal shell of the species is, however, quite a familiar object to many beachcombing, beachcombers. The shell of ''Spirula'' is extremely light in weight, very buoyant, and surprisingly durable; it very commonly floats ashore onto tropical beaches (and sometimes even temperate beaches) all over the world. This seashell is known to Conchology, shell collectors as the ram's horn shell or simply as ''Spirula''. Description ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
