The Zebra Shark:
Stripes or Spots?
By Taylor H.


What do they look like?
-
When Zebra Sharks are young, they have yellowish stripes on a dark background.
-
Once adults, the pattern changes
to small, dark spots on a grayish tan background.
-
Because of the change, Zebra Sharks
are often called Leopard Sharks.
-
The Zebra Shark is hard to confuse
with any other shark because of the ridges that run the length of the body
and tail (which is almost as long as the body).
Where Are They?
-
Zebra Sharks are often found around near shore reefs off the western Pacific
Ocean (Japan to Australia), the Indian Ocean and the Red Sea (the western
Pacific region).
A lot of the times they
are found on sandy bottoms.
Let's Eat!

Zebra
Sharks feed on reef mollusks, crustaceans, small bony fish, bivalves, sea
snails, crabs and shrimps.
-
This particular type of shark has
a flexible body which allows it to swim through narrow crevices and channels
in their search of food.
-
Zebra Sharks' teeth are loosely
attached to their jaws so it is possible for them to come out when they
eat.
-
Special tissue in the jaws of Zebra
Sharks regrow new teeth to replace the ones that have fallen out.

To reproduce a male Zebra Shark
lets his sperm in to the female's reproduction track using sperm like transfers

fin.
