Sharp-toothed deep divers
Ichthyosaurs had the largest eyes of any vertebrate animal – up to 10in-wide eyeballs.
The biggest were the size of a blue whale and could swim at 25mph.
Their sharp, needlelike teeth were used to catch squid and molluscs. ÷They were deep divers like modern whales. ÷Ichythyosaurs had fingers and toes, but these became encased in skin to form flippers.
