What is the biggest species of squid?
Colossal squid
The beak is considerably smaller than some found in the stomachs of sperm whales,[27][28] suggesting other colossal squid are much larger than this one.[27][28]
The eye is 27cm (11in) wide, with a lens 12cm (4.7in) across. This is the largest eye of any known animal.[6] These measurements are of the partly collapsed specimen; alive, the eye was probably 30[7] to 40cm (12 to 16 in) across.[29]
Inspection of the specimen with an endoscope revealed ovaries containing thousands of eggs.[7]
