The largest recorded specimen was a female, which are thought to be larger than males, captured in February 2007 by a New Zealand fishing boat in the Ross Sea off Antarctica. [31] The squid was close to death when it was captured and subsequently was taken back to New Zealand for scientific study. [51]
The giant squid has a sophisticated nervous system and complex brain, attracting great interest from scientists. It also has the largest eyes of any living creature except perhaps the colossal squid—up to at least 27 cm (11 in) in diameter, with a 9 cm (3 + 1 ⁄ 2 in) pupil (only the extinct ichthyosaurs are known to have had larger eyes). [18]
This is three times the size of the largest fish eyes—up to 90 mm (3.5 in) in swordfish—and more than twice the diameter of the largest whale eyes—up to 109 mm (4.3 in), 61 mm (2.4 in), and 55 mm (2.2 in) in blue, humpback, and sperm whales, respectively—which are the largest among vertebrates. [5]
They prey on a wide variety of creatures: fish, marine mammals like seals and dolphins, sea turtles, and cephalopods such as squid. While there is just one species of orca there are multiple ...
The largest known complete specimen of the colossal squid—and the heaviest recorded extant cephalopod—was a mature female captured in the Ross Sea in February 2007. Its weight was initially estimated at 450 kg (990 lb), its mantle length at 4 m (13 ft), and its total length at 8–10 m (26–33 ft). [15]
One giant squid specimen that washed ashore in 1878 in Newfoundland reportedly measured 16.8 m (55 ft) in total length (from the tip of the mantle to the end of the long tentacles), head and body length 6.1 m (20 ft), 4.6 m (15 ft) in circumference at the thickest part of mantle, and weighed about 900 kg (2,000 lb). This specimen is still often ...
A fisherman in northern Cambodia hooked what researchers say is the world’s largest freshwater fish — a giant stingray that scientists know relatively little about. Man hooks largest ...
N. pompilius is the largest species in the genus. One form from Indonesia and northern Australia, once called N. repertus, may reach 25.4 cm (10.0 in) in diameter. [24] However, most nautilus species never exceed 20 cm (8 in). Nautilus macromphalus is the smallest species, usually measuring only 16 cm (6 + 1 ⁄ 2 in).
