Potential enhanced ability of giant squid to detect sperm whales is an exaptation tied to their large body size

Abstract It has been hypothesized that sperm whale predation is the driver of eye size evolution in giant squid. 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...
