71. Some sharks close their eyes just before they bite. Although they cannot see their prey, their bites are on target. Researchers have noted that sharks often misdirect their bites at metal objects, and they can find batteries buried under the sand of an aquarium. This evidence suggests that sharks keep track of their prey during the split second before they bite in the same way that (A) a male silkworm moth locates a mate. (B) a platypus locates its prey in a muddy river. (C) a bat can find moths in the dark. (D) a Natworm avoids light places. (E) a rattlesnake finds a mouse in its burrow.
