Enoploteuthis
''Enoploteuthis'' is a genus of squid in the family Enoploteuthidae. The species of ''Enoploteuthis''are most easily recognised by having a larger tail when compared to the other genera in the Enoploteuthidae. The tail's size is emphasised not having the fins extending along its sides. In related genera there is a narrow extension of the fins along the tail. Other characteristics include the presence of suckers on the distal portion of arms IV where there at no photophores present; the tentacular club has two rows of hooks and no marginal suckers; on the buccal crown there are typical chromatophores on the aboral surface but on the oral surface there may be some light skin pigmentation. They have 9-10 photophores on the eye and they have complex photophores in the skin. In the females the Spermatangia receptacles are at the posterior junction of muscles used to retract the funnel and the muscles which retract the head. ''Enoploteuthis'' differs from other genera of the Enoploteuth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enoploteuthidae
The Enoploteuthidea are a family of squid comprising approximately 40 species in four genera. Most species have a mantle length ranging from 3–13 cm. Hooks are present on all arms and tentacles. The family is best known for the large array of photophores throughout the body.

Enoploteuthis Leptura
''Enoploteuthis leptura'', the hooked enope squid, is a species of squid from the family Enoploteuthidae. It is the type species of the genus ''Enoploteuthis'', which is in turn the type genus of the Enoploteuthidae. Description ''Enoploteuthis leptura'' have hooks on their arms, less on arms I-III than on arms IV, the males have many tiny papillae covering the oral surfaces of arms I-III. In males right arm IV is hectocotylised and has a flap created by an expansion of the ventral protective membrane and there are about six pairs of hooks on the distal third of the arm on the opposite side to the flap. On the dorsal side the protective membrane expands a little to create a series of small flaps on the other side of the arm from the large flap made by the ventral membrane. The tentacles are long and slender and the tentacular club is narrow with two rows of hooks on its manus, a ventral series having 6-7 large hooks and a dorsal series with 4-5 smaller hooks.

Celebes Sea
The Celebes Sea, (; ms, Laut Sulawesi, id, Laut Sulawesi, fil, Dagat Selebes) or Sulawesi Sea, of the western Pacific Ocean is bordered on the north by the Sulu Archipelago and Sulu Sea and Mindanao Island of the Philippines, on the east by the Sangihe Islands chain, on the south by Sulawesi's Minahasa Peninsula, and on the west by northern Kalimantan in Indonesia. It extends 420 miles (675 km) north-south by east-west and has a total surface area of , to a maximum depth of . South of the Cape Mangkalihat, the sea opens southwest through the Makassar Strait into the Java Sea. The Celebes Sea is a piece of an ancient ocean basin that formed 42 million years ago in a locale removed from any landmass. By 20 million years ago, earth crust movement had moved the basin close enough to the Indonesian and Philippine volcanoes to receive emitted debris. By 10 million years ago the Celebes Sea was inundated with continental debris, including coal, which was shed from a gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spermatangia
A gametangium (plural: gametangia) is an organ or cell in which gametes are produced that is found in many multicellular protists, algae, fungi, and the gametophytes of plants. In contrast to gametogenesis in animals, a gametangium is a haploid structure and formation of gametes does not involve meiosis. Types of gametangia Depending on the type of gamete produced in a gametangium, several types can be distinguished. Female Female gametangia are most commonly called archegonia. They produce egg cells and are the sites for fertilization. Archegonia are common in algae and primitive plants as well as gymnosperms. In flowering plants, they are replaced by the embryo sac inside the ovule. Male The male gametangia are most commonly called antheridia. They produce sperm cells that they release for fertilization. Antheridia producing non-motile sperm (spermatia) are called spermatangia. Some antheridia do not release their sperm. For example, the oomycete antheridium ...
