 The mom doesn’t stay with the baby. It just leaves it
behind.

shark with moving.
Behavioral Adaptations

 They team up with a certain fish that can eat little parasites off the skin.
This protects them from skin infection
 Hammerheads stay in a “school” when they try to choose mates.
 Migrate long distances to give birth because they need the warmer
water
 Their eyes roll back in their head when they attack to protect them
from being damaged.
Physiological Adaptations
 Bones made of cartilage
for flexibility.
 The Ampullae of
Lorenzini is a sensor so
the shark can catch its
prey in dark waters.
 Good sense of smell
which helps them smell
blood from far away.
 Gills take oxygen out of
water which is how they
breathe.
