Hi there, I’ve been creating a hand-drawn noir comic book called ‘Lobstertown Tales’ and I greatly appreciated your article on the squid diet as I’m working on a squid restaurant scene.
Over half of this biomass is eaten by whales, seals, penguins, seabirds, squid, and fish each year. Most krill species display large daily vertical migrations, providing food for predators near the surface at night and in deeper waters during the day. Krill are fished commercially in the Southern Ocean and in the waters around Japan.
In 2015, molecular evidence was published indicating that cephalopod chromatophores are photosensitive; reverse transcription polymerase chain reactions (RT-PCR) revealed transcripts encoding rhodopsin and retinochrome within the retinas and skin of the longfin inshore squid (Doryteuthis pealeii), and the common cuttlefish (Sepia officinalis ...
The krill infected by third stage larvae are then ingested by common predators, such as squid and fish, specifically teleosts, who then become paratenic hosts. [3] These hosts are referred to as paratenic because third stage larvae do not develop further when inhabiting them. [ 5 ]
Brachioteuthidae is a family of squid containing two genera and around seven species. They are muscular, but rather thin squids with a ML up to ~20 cm. The tentacle club is unique in this family in that the dactylus is normal (usually 3-4 sucker series), while the manus is greatly expanded with numerous small suckers on stalks.
Larger capelin also eat a great deal of krill and other crustaceans. Among others, whales, seals, Atlantic cod, Atlantic mackerel, squid and seabirds prey on capelin, in particular during the spawning season while the capelin migrate south. Capelin spawn on sand and gravel bottoms or sandy beaches at the age of two to six years.
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. [ 2 ] H. heteropsis live in the ocean's mesopelagic zone and are found in the California Current and the Humboldt Current . [ 4 ]
They feed on moderately sized fish, squid, and krill. Several species of the southern fur seal also have sea birds, especially penguins, as part of their diets. [2] [3] Fur seals, in turn, are preyed upon by sharks, orcas, and occasionally by larger sea lions. These opportunistic mammals tend to feed and dive in shallow waters at night, when ...
