Sepiolina Petasus
''Sepiolina petasus'' is a species of bobtail squid in the genus ''Sepiolina'' in the subfamily Heteroteuthidinae of the family Sepiolidae. It was originally collected in the Pacific Ocean near the Okinawa Islands. It was found to be sympatric with ''Sepiolina nipponensis ''Sepiolina nipponensis'', also known as the Japanese bobtail squid, is a bobtail squid and one of two species in the genus ''Sepiolina''.

Bobtail Squid
Bobtail squid (order Sepiolida) are a group of cephalopods closely related to cuttlefish. Bobtail squid tend to have a rounder mantle than cuttlefish and have no cuttlebone. They have eight suckered arms and two tentacles and are generally quite small (typical male mantle length being between ). Sepiolids live in shallow coastal waters of the Pacific Ocean and some parts of the Indian Ocean and Atlantic Ocean as well as in shallow waters on the west coast of the Cape Peninsula off South Africa. Like cuttlefish, they can swim by either using the fins on their mantle or by jet propulsion. They are also known as "dumpling squid" (owing to their rounded mantle) or "stubby squid". Light organ Bobtail squid have a symbiotic relationship with bioluminescent bacteria ('' Aliivibrio fischeri''), which inhabit a special light organ in the squid's mantle. The luminescent properties of the bacteria regulate gene expression in the light organ. The bacteria are fed a sugar and amino ac ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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 of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Subfamily
In biological classification, a subfamily ( Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae".

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

Okinawa Islands
The Okinawa Islands ( or ) are an island group in Okinawa Prefecture, Japan and are the principal island group of the prefecture. The Okinawa Islands are part of the larger Ryukyu Islands group and are located between the Amami Islands of Kagoshima Prefecture to the northeast and the Sakishima Islands of Okinawa Prefecture to the southwest. The Okinawa Islands, apart from the main island, contain three smaller island groups: the Kerama, Yokatsu and Iheya-Izena island groups. The Okinawa Islands are the political, cultural and population center of Okinawa Prefecture. The prefectural capital of Naha is within the island group. 90% of the population of the prefecture reside within the Okinawa Islands, primarily on the largest island of the group, Okinawa Island. Access to the various Okinawa Islands is primarily via small airports which connect to Naha Airport. Additionally, the islands are connected via ferry service to the Port of Naha in the prefectural capital. The Okinaw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sympatry
In biology, two related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter one another. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and do n ...
