21 Ecosystems The giant squid, which is found deep in the ocean, has some of the biggest eyes in the entire animal kingdom. How have these large eyes helped the squid survive? a. The large eyes help the giant squid see prey in the darkness of the deep ocean. b. The eyes act as lights and attract prey for the giant squid. c.
