The perceived pitch of a sound depends on

The sand grains or other dense materials resting on mechanoreceptors used by most invertebrates to sense gravity are called

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
