It may not surprise you to learn that the size of a whale’s eye depends on the type of whale. Future studies should target the mechanism behind the evolution of large body size, not eye size. Sperm whales can become entangled in many different types of fishing gear, including trap lines, pots, and gillnets. The photographer Bryant Austin makes life-size composites of whales: humpbacks, sperm whales, minkes. But when Rowan Jacobsen had a … Given that the eyes of giant squid have the size expected for a squid this big, it is likely that any enhanced ability of giant squid to detect whales is an exaptation tied to their body size. The eye of the sperm whale is the largest among the other toothed whales with an overall ellipsoid structure having a dimension of about 7 cm length, 7 cm breadth, and about 3 cm in thickness. Each of the eyes is the largest among the toothed whales, weighing about 170 g each.
