Lycoteuthidae
The Lycoteuthidae are a family of squid comprising four known genera in two subfamilies. They are small muscular squid characterised by a lack of hooks and by photophores present on the viscera, eyeballs and tentacles. They inhabit tropical and subtropical seas where the diel migrants which stay down in the mesopelagic zone during the day and migrate to the surface to feed at night. Some species show strong sexual dimorphism Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction.

Lycoteuthinae
Lycoteuthinae is a subfamily of squid from the family Lycoteuthidae. They are found in tropical and subtropical waters. They are characterised by the possession of oval photophores on the tentacles, eyeballs and viscera in all species and on the arms, head, mantle and fins in some. Some species also show strong sexual dimorphism. The subfamily contains all of the species classified under Lycoteuthidae, except for '' Lampadioteuthis megaleia'' which differs from the Lycoteuthins by the bearing of a hectocotylised arm in males. Genera and species The taxa within the subfamily Lycoteuthinae are: *''Lycoteuthis'' Pfeffer, 1900 **''Lycoteuthis lorigera'' ( Steenstrup, 1875) **''Lycoteuthis springeri'' (Voss, 1956) *'' Nematolampas'' Berry, 1913 **'' Nematolampas regalis'' Berry, 1913 **'' Nematolampas venezuelensis'' Arocha, 2003 *''Selenoteuthis ''Selenoteuthis'' is a monotypic genus of squid from the family Family (from la, familia) is a group of people related either by ...

Lampadioteuthis Megaleia
''Lampadioteuthis megaleia'' is a small, colorful squid from the family Lycoteuthidae, it is the only species in the only genus in the monotypic subfamily Lampadioteuthinae, it is sometimes known as the wonderful firefly squid. It differs from the other species of the Lycoteuthidae mainly by having a hectocotylus in the males and by the possession of a rostrum on the gladius. Description ''Lampadioteuthis megaleia'' is a small squid which grows to a mantle length of 40 mm. In males the right ventral arm is hectocotylized with an enlarged protective membrane over the mid-arm. It has four ocular photophores, arranged as three in a ventral line and one positioned laterally. The tentacles have five photophores which are set on a stalk. There are circular anal photophores on either side of the rectum, single elongated branchial photophores lie at the base of each gill, there are no abdominal photophores and a single photophore is situated to the rear of the abdomen between the i ...

Nematolampas Regalis
''Nematolampas regalis'', the regal firefly squid is a small, little-known species of squid from the family Lycoteuthidae which is found in the subtropical South Pacific Ocean. This squid has a mantle length of 30mm. It may be sexually dimorphic, with the males possibly having very thin elongated arms III, which are increasingly thread like towards their tips, where they do not have any suckers. Arms II are "normal" and have suckers along their length. The third arms have a series of photophores along their length, and there is a small photophore located on each of the tips of arms I and II. The tentacles have two embedded photophores and the largest of the eye's photophores is in the centre. There is a pair of large photophores close to the tip of the mantle on the ventral side mantle, with no other photophores on the body except for a visceral photophore which is also near the tip. There is practically no tail. ''N. regalis'' is known only from the Kermadec Islands The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nematolampas
''Nematolampas'' is a genus of squid from the family Lycoteuthidae. The genus comprises two species both of which are known from only a few males. The type species, ''Nematolampas regalis'' has been recorded from the subtropical South Pacific and the second species, '' Nematolampas venezuelensis'', is from the tropical western North Atlantic. The main distinguishing feature of this genus is that arms III are very elongated and thread-like and have no suckers near their tips. As only males have been captured it is not known if this feature is present in females. Species There are currently two species classified under this genus: *''Nematolampas regalis ''Nematolampas regalis'', the regal firefly squid is a small, little-known species of squid from the family Lycoteuthidae which is found in the subtropical South Pacific Ocean.

Lycoteuthis Springeri
''Lycoteuthis springeri'' is a small species of rarely captured squid from the family Lycoteuthidae. It has three photophores on the posterior portion of the abdomen and the males have a long tail which bears seven deeply embedded long and thin photophores. The males also have photophores on arms II and III, as well as on the head and the mantle. The tentacular clubs and the structure of the suckers on the club and arm are not distinctive. Two of the known specimens were males which had mantle lengths of 80mm and 97mm. The type locality was in the Gulf of Mexico and the holotype A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described.

Squid
True squid are molluscs with an elongated soft body, large eyes, eight arms, and two tentacles in the superorder Decapodiformes, though many other molluscs within the broader Neocoleoidea are also called squid despite not strictly fitting these criteria. Like all other cephalopods, squid have a distinct head, bilateral symmetry, and a mantle. They are mainly soft-bodied, like octopuses, but have a small internal skeleton in the form of a rod-like gladius (cephalopod), gladius or pen, made of chitin. Squid diverged from other cephalopods during the Jurassic and occupy a similar role to teleost fish as open water predators of similar size and behaviour. They play an important role in the open water food web. The two long tentacles are used to grab prey and the eight arms to hold and control it. The beak then cuts the food into suitable size chunks for swallowing. Squid are rapid swimmers, moving by Aquatic locomotion#Jet propulsion, jet propulsion, and largely locate their ...

Tentacle
In zoology, a tentacle is a flexible, mobile, and elongated organ present in some species of animals, most of them invertebrates. In animal anatomy, tentacles usually occur in one or more pairs. Anatomically, the tentacles of animals work mainly like muscular hydrostats. Most forms of tentacles are used for grasping and feeding. Many are sensory organs, variously receptive to touch, vision, or to the smell or taste of particular foods or threats. Examples of such tentacles are the eyestalks of various kinds of snails. Some kinds of tentacles have both sensory and manipulatory functions. A tentacle is similar to a cirrus, but a cirrus is an organ that usually lacks the tentacle's strength, size, flexibility, or sensitivity. A nautilus has cirri, but a squid has tentacles. Invertebrates Molluscs Many molluscs have tentacles of one form or another. The most familiar are those of the pulmonate land snails, which usually have two sets of tentacles on the head: when extended ...
