Histioteuthis Meleagroteuthis
''Histioteuthis meleagroteuthis'' is a species of small to medium squids that have a dark, wine red skin pigment. Females at maturity average at 114mm in length, while males at maturity average at 65-102mm in length.Voss, N. A. and Sweeney, M. J. 1998. "Systematics and Biogeography of cephalopods. Volume II." Smithsonian Contributions to Zoology. 277–599. https://doi.org/10.5479/si.00810282.586.277 This species is characterized by tubercles, photophores, and asymmetric features. This species can be found in circumglobal, mesopelagic waters. Description Tubercles ''Histioteuthis meleagroteuthis'' have a line of protuberant tubercles which run along the front of the dorsal midline on the squid's mantle. These tubercles are cartilaginous and are very stiff. In the young stages of development, small tubercles can be found in a row on the mantle and more tubercles appear throughout development. Photophores Compound photophores are found on the anterior of the mantle in a ver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wikipedia Student Program
Wikipedia is a multilingual free online encyclopedia written and maintained by a community of volunteers, known as Wikipedians, through open collaboration and using a wiki-based editing system. Wikipedia is the largest and most-read reference work in history. It is consistently one of the 10 most popular websites ranked by Similarweb and formerly Alexa; Wikipedia was ranked the 5th most popular site in the world. It is hosted by the Wikimedia Foundation, an American non-profit organization funded mainly through donations. Wikipedia was launched by Jimmy Wales and Larry Sanger on January 15, 2001. Sanger coined its name as a blend of ''wiki'' and ''encyclopedia''. Wales was influenced by the "spontaneous order" ideas associated with Friedrich Hayek and the Austrian School of economics after being exposed to these ideas by the libertarian economist Mark Thornton.

Molluscs Described In 1910
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant taxon, extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine biology, marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater mollusc, freshwater and Terrestrial molluscs, terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 Taxonomy (biology), taxonomic class (biology), classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurobiology, neurologically advanced of all inve ...
