Jellyella
''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] |
Eliza Catherine Jelly
Eliza Catherine Jelly (28 September 1829 - 3 November 1914) was an English bryozoologist. She was one of the first women to work and publish in the field of bryozoology. Her 1889 text ''The Synonymic Catalogue of the Recent Marine Bryozoa'' is still used as a reference material. Early life Eliza Catherine Jelly was born in Bath, Somerset, the daughter of Harry Jelly, an Anglican clergyman, and Eliza Jelly (née Cave), who came from a family of builders in Bath. Her father Harry, orphaned as an infant, was a naturalist and had long been interested in paleontology, and frequently went searching for fossils, plants, and insects. He is recorded as having donated fossils from Wiltshire to the Bath Literary and Philosophical Institute in 1826. He later took a fossil-collecting trip to Jamaica and donated these specimens to the Geological Society of London in September 1839. The Jelly family lived in Bath and Bristol until Eliza was about 13 years old. The family later moved to Devon w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudoplanktonic
Pseudoplanktonic organisms are those that attach themselves to planktonic organisms or other floating objects, such as drifting wood, buoyant shells of organisms such as ''Spirula'', or man-made flotsam. Examples include goose barnacles and the bryozoan ''Jellyella''. By themselves these animals cannot float, which contrasts them with true planktonic organisms, such as ''Velella'' and the Portuguese Man o' War The Portuguese man o' war (''Physalia physalis''), also known as the man-of-war, is a marine hydrozoan found in the Atlantic Ocean and the Indian Ocean. It is considered to be the same species as the Pacific man o' war or blue bottle, which is ..., which are buoyant. Pseudoplankton are often found in the guts of filtering zooplankters.

Membraniporidae
Membraniporidae is a bryozoan family in the order Cheilostomatida. '' Membranipora'' form encrusting or erect colonies; they are unilaminar or bilaminar and weakly to well-calcified. Zooids have vertical and basal calcified walls, but virtually no frontal calcified wall: most of the frontal surface is occupied by frontal membrane. An intertentacular organ is also present. The larvae are not brooded. The ancestrula is generally twinned. Kenozooids may be present in a few species; modified zooids analogous to avicularia ''Avicularia'' is a genus of the family Theraphosidae containing various species of arboreal tarantulas. The genus is native to Panama, the Caribbean and tropical South America. Each species in the genus has very distinguishable pink foot pads. ... are rare.

Alga
Algae (; singular alga ) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as ''Chlorella,'' ''Prototheca'' and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to in length. Most are aquatic and autotrophic (they generate food internally) and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the ''Charophyta'', a division of green algae which includes, for example, ''Spirogyra'' and stoneworts. No definition of algae is generally accepted. One definition is that algae "have chlorophyll ''a'' as their primary photosynthetic pigment and lack a sterile covering of cells around t ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Kelp
Kelps are large brown algae seaweeds that make up the order Laminariales. There are about 30 different genera. Despite its appearance, kelp is not a plant - it is a heterokont, a completely unrelated group of organisms. Kelp grows in "underwater forests" (kelp forests) in shallow oceans, and is thought to have appeared in the Miocene, 5 to 23 million years ago. The organisms require nutrient-rich water with temperatures between . They are known for their high growth rate—the genera ''Macrocystis'' and '' Nereocystis'' can grow as fast as half a metre a day, ultimately reaching .Thomas, D. 2002. ''Seaweeds.'' The Natural History Museum, London, p. 15. Through the 19th century, the word "kelp" was closely associated with seaweeds that could be burned to obtain soda ash (primarily sodium carbonate). The seaweeds used included species from both the orders Laminariales and Fucales. The word "kelp" was also used directly to refer to these processed ashes. Description In most kelp ...

Benthic
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. The name comes from ancient Greek, βÎνθος (bénthos), meaning "the depths." Organisms living in this zone are called benthos and include microorganisms (e.g., bacteria and fungi) as well as larger invertebrates, such as crustaceans and polychaetes. Organisms here generally live in close relationship with the substrate and many are permanently attached to the bottom. The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud. Description Oceans The benthic region of the ocean begins at the shore line (intertidal ...
