Sharks – Top of the food Chain

Creature Focus:                Tiger Shark

Habitat:                                From open oceans, to shallow nearshore reefs

Conservation Status:      Near threatened

Threats:                               Fishing, shark finning

 

Researcher Note: 

When tiger sharks reproduce, they develop the eggs inside their bodies but do not lay them.  Instead the embryos hatch within their mother’s uterus and grow to be juvenile sharks before being born.  This is known as aplacental viviparity or ovoviviparity.
