Although some sharks close their eyes just before they bite, their bites are on target. Researchers have noted that sharks often misdirect their bites at metal objects and that they can find batteries buried under sand. This evidence suggests that sharks keep track of their prey during the split second before they bite in the same way that A. a rattlesnake finds a mouse in its burrow. B. an insect avoids being stepped on. C. a star-nosed mole locates its prey in tunnels. D. a platypus locates its prey in a muddy river.
