The squid giant axon is the very large (up to 1.5 mm in diameter; typically around 0.5 mm) axon that controls part of the water jet propulsion system in squid.
When the glass squid keeps the sacs closed, its body is see-through, making it invisible to predators and prey. The sacs look like tiny polka dots covering its translucent body.
Perhaps the best video of a live colossal squid is that of an animal recorded at the surface in the D'Urville Sea off Antarctica in January 2008. [21] The squid was pulled to the surface feeding on a line-caught toothfish. The video is likely the first to show a colossal squid swimming freely, and records the animal performing a slow roll on ...
Loligo is a genus of squid and one of the most representative and widely distributed groups of myopsid squid.. The genus was first described by Jean Baptiste Lamarck in 1798. . However, the name had been used earlier than Lamarck (Schneider, 1784; Linnaeus, 1758) and might even have been used by Pli
The list includes records of giant squid (genus Architeuthis) either supported by a physical specimen (or parts thereof) or—in the absence of any saved material—where at least one of the following conditions is satisfied: the specimen was examined by an expert prior to disposal and thereby positively identified as a giant squid; a ...
A prosection is the dissection of a cadaver (human or animal) or part of a cadaver by an experienced anatomist in order to demonstrate for students anatomic structure. [1] In a dissection, students learn by doing; in a prosection, students learn by either observing a dissection being performed by an experienced anatomist or examining a specimen that has already been dissected by an experienced ...
Bigfin squids are a group of rarely seen cephalopods with a distinctive morphology.They are placed in the genus Magnapinna and family Magnapinnidae. [2] Although the family was described only from larval, paralarval, and juvenile specimens, numerous video observations of much larger squid with similar morphology are assumed to be adult specimens of the same family.
First video of live adult giant squid. Specimen was hooked when it attempted to eat a neon flying squid (Ommastrephes bartramii; c. 55 cm ML), which was itself attracted by bait of Japanese flying squid (Todarodes pacificus; c. 25 cm ML). Countershading and forceful ejection of water observed at surface. Sexual maturity determined based on ...
