Histioteuthidae
Histioteuthidae is a family of Oegopsid squid. The family was previously considered to be monotypic but the World Register of Marine Species assigns two genera to this family. The species classified under Histioteuthidae are mostly weakly muscled, moderately sized squid with a maximum mantle length of 33 cm. They generally have very long, robust arms and a short mantle with small, rounded fins. Their main distinguishing feature is that the eyes are different sizes and orient in different vertical directions. The larger left eye is semitubular, mobile, generally is directed back and up as indicated by the pattern of iridophores on the eye's outer surface. This means that when the squid is positioned obliquely the eye is pointed upwards towards the surface. It is thought that this is used to detect animals above the squid silhouetted against the sun during the day. The right eye has a normal shape and is oriented laterally and slightly downward. This arrangement gives the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 jet propulsion, and largely locate their prey by sight. They are among the most intelligent o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Histioteuthis Heteropsis
''Histioteuthis heteropsis'' (''H. heteropsis''), also known as the strawberry squid, is a species of small cock-eyed squid. The scientific nomenclature of these squid stems from their set of differently sized eyes, one being small and blue and the other being large and yellow. It is thought that the large eye is used to see objects against dim light, while the smaller eye is more able to view bioluminescent light sources. The squid’s vernacular name arose due to its rich red skin pigmentation and the presence of photophores along its body, making it appear like a strawberry with seeds. ''H. heteropsis'' live in the ocean’s mesopelagic zone and are found in the California Current and the Humboldt Current. Little is known about their specific feeding and mating behaviors, although their inking patterns have been subject to study. They are not easily disturbed, and only ink when provoked. ''H. heteropsis'' was discovered by Berry in 1913 and exhibited publicly for the first t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Histioteuthis Miranda
''Histioteuthis'' is a genus of squid in the family Histioteuthidae. It goes by the common name cock-eyed squid, because in all species the right eye is normal-sized, round, blue and sunken; whereas the left eye is at least twice the diameter of the right eye, tubular, yellow-green, faces upward, and bulges out of the head. In 2017, researchers at Duke University established that ''Histioteuthis'' uses its larger eye to see ambient sunlight, and its smaller eye to detect bioluminescence from prey animals.Mismatched Eyes Help Squid Survive Ocean’s Twilight Zone at Duke University; by Kara Manke; published February 13, 2017; retrieved June 25, 2017 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
