Todarodes Pusillus
The little flying squid (''Todarodes pusillus'') is a species of squid, one of the arrow squids of the genus ''Todarodes, in the subfamily ''Todarodinae of the flying squid Family (biology), family Ommastrephidae. It is a small species from the waters around northern Australia and Indonesia. Description The little flying squid is said to be dwarf species of flying squid compared to the other species of ''Todarodes'', the largest female recorded to date had a Mantle (mollusc), mantle length of 74mm and the largest male measured 68mm mantle. The maximum mantle length is not thought to exceed 100mm, compared to 500mm for the Japanese flying squid. It also has relatively small fins which only have a length equivalent to 25 to 31% of the mantle length (35-40% in the Japanese flying squid). It has a cylindrical, muscular body, typical of related species, which tapers to a short, pointed tail. Its fourth right Cephalopod arm, arm bears a hectocotylus on the distal half and has 11-13 norm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Manus (anatomy)
The manus (Latin for '' hand'', plural manus) is the zoological term for the distal portion of the forelimb of an animal. In tetrapods, it is the part of the pentadactyl limb that includes the metacarpals and digits ( phalanges). During evolution, it has taken many forms and served a variety of functions. It can be represented by the hand of primates, the lower front limb of hoofed animals or the forepaw and is represented in the wing of birds, bats and prehistoric flying reptiles ( pterosaurs), the flipper of marine mammals and the 'paddle' of extinct marine reptile Reptiles, as commonly defined, are a group of tetrapods with an ectothermic metabolism and Amniotic egg, amniotic development. Living traditional reptiles comprise four Order (biology), orders: Testudines, Crocodilia, Squamata, and Rhynchocepha ...s, such as plesiosaurs and ichthyosaurs. In cephalopods, the ''manus'' is the end, broader part of a tentacle, and its suckers are often larger and arrange ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cephalopods Described In 1988
A cephalopod is any member of the molluscan Taxonomic rank, class Cephalopoda (Greek language, Greek plural , ; "head-feet") such as a squid, octopus, cuttlefish, or nautilus. These exclusively marine animals are characterized by bilateral symmetry, bilateral body symmetry, a prominent head, and a set of cephalopod arm, arms or tentacles (muscular hydrostats) modified from the primitive molluscan foot. Fishers sometimes call cephalopods "inkfish", referring to their common ability to squirt Cephalopod ink, ink. The study of cephalopods is a branch of malacology known as teuthology. Cephalopods became dominant during the Ordovician period, represented by primitive nautiloids. The class now contains two, only distantly related, Extant taxon, extant subclasses: Coleoidea, which includes octopuses, squid, and cuttlefish; and Nautiloidea, represented by ''Nautilus (genus), Nautilus'' and ''Allonautilus''. In the Coleoidea, the molluscan shell has been internalized or is absent, where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

Spermatophore
A spermatophore, from Ancient Greek σπέρμα (''spérma''), meaning "seed", and -φόρος (''-phóros''), meaning "bearing", or sperm ampulla is a capsule or mass containing spermatozoa created by males of various animal species, especially salamanders and arthropods, and transferred in entirety to the female's ovipore during reproduction. Spermatophores may additionally contain nourishment for the female, in which case it is called a nuptial gift, as in the instance of bush crickets. In the case of the toxic moth '' Utetheisa ornatrix'', the spermatophore includes sperm, nutrients, and pyrrolizidine alkaloids which prevent predation because it is poisonous to most organisms. However, in some species such as the Edith's checkerspot butterfly, the "gift" provides little nutrient value. The weight of the spermatophore transferred at mating has little effect on female reproductive output. Arthropods Spermatophores are the norm in arachnid Arachnids are arthro ...

Oviduct
The oviduct in vertebrates is the passageway from an ovary. In human females, this is more usually known as the fallopian tube. The eggs travel along the oviduct. These eggs will either be fertilized by spermatozoa to become a zygote, or will degenerate in the body. Normally, these are paired structures, but in birds and some cartilaginous fishes, one or the other side fails to develop (together with the corresponding ovary), and only one functional oviduct can be found. Except in teleosts, the oviduct is not directly in contact with the ovary. Instead, the most anterior portion ends in a funnel-shaped structure called the infundibulum, which collects eggs as they are released by the ovary into the body cavity. The only female vertebrates to lack oviducts are the jawless fishes. In these species, the single fused ovary releases eggs directly into the body cavity. The fish eventually extrudes the eggs through a small genital pore towards the rear of the body. Fish and amphibia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Torres Strait
The Torres Strait (), also known as Zenadh Kes ( Kalaw Lagaw Ya#Phonology 2, [ˈzen̪ad̪ kes]), is a strait between Australia and the Melanesian island of New Guinea. It is wide at its narrowest extent. To the south is Cape York Peninsula, the northernmost extremity of the Australian mainland. To the north is the Western Province (Papua New Guinea), Western Province of Papua New Guinea. It is named after the Spanish navigator Luís Vaz de Torres, who sailed through the strait in 1606. History Pre-colonisation The islands of the Torres Strait have been inhabited by humans for at least 2,500 years and possibly much longer. The various Torres Strait Islanders, Torres Strait Islander communities have a unique culture and long-standing history with the islands and nearby coastlines. Their maritime-based trade and interactions with the Papuans to the north and the Australian Aborigines, Australian Aboriginal communities have maintained a steady cultural diffusion among the th ...

Timor Sea
The Timor Sea (, , or ) is a relatively shallow sea in the Indian Ocean bounded to the north by the island of Timor with Timor-Leste to the north, Indonesia to the northwest, Arafura Sea to the east, and to the south by Australia. The Sunda Trench marks the deepest point of the Timor Sea with a depth of more than 3300 metres, separating the continents of Oceania in the southeast and Asia to the northwest and north. The Timor sea is prone to earthquakes and tsunamis north of the Sunda Trench, due to its location on the Ring of Fire as well as volcanic activity and can experience major cyclones, due to the proximity from the Equator. The sea contains a number of reefs, uninhabited islands and significant hydrocarbon reserves. International disputes emerged after the reserves were discovered resulting in the signing of the Timor Sea Treaty. The Timor Sea was hit by the worst Montara oil spill, oil spill for 25 years in 2009. It is possible that Australia's first inhabitants cros ...

Continental Slope
A continental margin is the outer edge of continental crust abutting oceanic crust under coastal waters. It is one of the three major zones of the ocean floor, the other two being deep-ocean basins and mid-ocean ridges. The continental margin consists of three different features: the continental rise, the continental slope, and the continental shelf. Continental margins constitute about 28% of the oceanic area. Subzones The continental shelf is the relatively shallow water area found in proximity to continents; it is the portion of the continental margin that transitions from the shore out towards to ocean. Continental shelves are believed to make up 7% of the sea floor. The width of continental shelves worldwide varies in the range of 0.03–1500 km. The continental shelf is generally flat, and ends at the shelf break, where there is a drastic increase in slope angle: The mean angle of continental shelves worldwide is 0° 07′, and typically steeper closer to the coa ...
