Page 13 - Sharks teeth to tail

Sharks don’t have especially acute eyesight but they do have one adaptation that humans lack: a a a a a a tapetum lucidum (Latin for “bright tapestry”) a a a membrane inside their eyes that reflects light This tissue allows sharks to see better in deep underwater or murky conditions This added enhancement comes
at a a a a cost: a a a a shark’s eyesight is blurrier than a a a human’s Eyes with tapetum lucida reflect a a a greenish- yellow light similar to what may be seen when when photographing a a a cat or dog when when the light reflects out from their eyes at night 11
