Huge squids 'talk' to each other ... using colors
Ommastrephinae includes the largest species of squids belonging to the family Ommastrephidae, Humboldt squid (Dosidicus gigas) which can grow to 1.5 metres (4.9 ft) in mantle length (ML). [3] It also contains the smallest squid species belonging to the family, the glass squid ( Hyaloteuthis pelagica ) which has a mantle length of only up to 9 ...
Roger Uzun, a veteran scuba diver and amateur underwater videographer, swam with a swarm of Humboldt squid for approximately 20 minutes, later saying they seemed more curious than aggressive. [36] When not feeding or being hunted, Humboldt squid exhibit curious and intelligent behavior. [37]
The Humboldt squid is also known to quickly devour larger prey when cooperatively hunting in groups. Humboldt squid are known for their speed in feasting on hooked fish, sharks, and squid, even from their own species and shoal, [128] and have been known to attack fishermen and divers. [129]
Attempts to capture a glimpse of a live giant squid—described as "the most elusive image in natural history" [44] —were mooted since at least the 1960s. [45] Efforts intensified significantly towards the end of the century, with the launch of several multi-million-dollar expeditions in the late 1990s, though these were all unsuccessful.
A frame from the first colour film of a live giant squid in its natural habitat, [nb 1] recorded from a manned submersible off Japan's Ogasawara Islands in July 2012. The animal (#549 on this list) is seen feeding on a 1-metre-long Thysanoteuthis rhombus (diamondback squid), which was used as bait in conjunction with a flashing squid jig. [2]
Gilly's current research program on squid concentrates on the behavior and physiology of Dosidicus gigas, the jumbo or Humboldt squid.Fieldwork in the Gulf of California [2] [3] near Santa Rosalía, Baja California Sur [4] and off Monterey Bay employs a variety of tagging methodologies in order to track short-term diel vertical migrations as well as long-distance migrations.
