Dendrilla Lacunosa
''Ernstilla'' is a genus of sea sponges and is the only genus in the monotypic family Ernstillidae. It is represented by a single species ''Ernstilla lacunosa''. Taxonomy The genus emerged from an examination of species then classified as ''Dendrilla lacunosa'' by Ernst Hentschel in 1912, describing specimens collected in Indonesia and later discovered at the Kimberley and northwest coast of Australia. The Western Australian researcher Jane Fromont observed that the form of the species, long and whip-like, resembled other classifications and not the small delicate structure of other '' Dendrilla'' species. The initial examination required international research to complete, and the result was the identification of a new genus and family, allied to the Verongiida order. The study discovered that while resembling the morphology of the former classification, the skeletal structure of the species was suspected and confirmed to contain chitin Chitin ( C8 H13 O5 N)n ( ) is a lon ...

Sea Sponges
Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges were first to branch off the evolutionary tree from the last common ancestor of all animals, making them the sister group of all other animals. Etymology The term ''sponge'' derives from the Ancient Greek word ( 'sponge'). Overview Sponges are similar to other animals in that they are multicellular, ...

Jane Fromont
Phyllis Jane Fromont is a New Zealand and Australian scientist specialising in sponges. Early life and education Fromont was raised in Whanganui, New Zealand, the youngest of six children. She became interested in marine biology after scuba diving in Northland, and completed a Bachelor of Science degree that included some marine biology papers at the University of Auckland. She then undertook her overseas experience for about two years, before arriving in Perth, Western Australia, where she found work with an environmental consultancy firm and was a volunteer at the Western Australian Museum with curator of marine invertebrates, Loisette Marsh. After attending a workshop in Melbourne on sponges led by Patricia Bergquist and Felix Wiedenmayer, she was encouraged by Bergquist to return to Auckland for postgraduate study. She earned a Master of Science degree from the University of Auckland in 1985, with her thesis titled ''Poecilosclerida of New Zealand'', and while there publish ...

Verongiida
Verongiida (also known as Verongida) is an order of sea sponges within the phylum Porifera. The "skeleton" in these sponges is made up of spongin, rather than of spicules. They live in marine environments. The name was proposed by Patricia Bergquist Dame Patricia Rose Bergquist (née Smyth, 10 March 1933 – 9 September 2009) was a New Zealand zoologist who specialised in anatomy and taxonomy. At the time of her death, she was professor emerita of zoology and honorary professor of anatomy ... in 1978.

Chitin
Chitin ( C8 H13 O5 N)n ( ) is a long-chain polymer of ''N''-acetylglucosamine, an amide derivative of glucose. Chitin is probably the second most abundant polysaccharide in nature (behind only cellulose); an estimated 1 billion tons of chitin are produced each year in the biosphere. It is a primary component of cell walls in fungi (especially basidiomycetes and filamentous fungi), the exoskeletons of arthropods such as crustaceans and insects, the radulae, cephalopod beaks and gladii of molluscs and in some nematodes and diatoms. It is also synthesised by at least some fish and lissamphibians. Commercially, chitin is extracted from the shells of crabs, shrimps, shellfishes and lobsters, which are major by-products of the seafood industry. The structure of chitin is comparable to cellulose, forming crystalline nanofibrils or whiskers. It is functionally comparable to the protein keratin. Chitin has proved useful for several medicinal, industrial and biotechnological purpos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
