Terrick and Colleagues (1995) Offered Garter Snakes (Thamnophis Radix) Fish

Multiple Choice

Terrick and colleagues (1995) offered garter snakes (Thamnophis radix) fish presented on aposematically colored forceps or fish presented on nonaposematically colored forceps. The snakes were then injected with lithium chloride, which made them ill. The snakes that had been offered fish on aposematically colored forceps had a much longer-lasting aversion to fish than those that had been offered fish on the nonaposematically colored forceps. This suggests that the response of at least some predators to aposematic coloration may be

A) innate.
B) instantaneous.
C) largely based on the olfactory system.
D) learned.
