Photos from the field

Here's a picture of one of our volunteer assistants, Sean, holding a 307 cm female tiger shark. See how her stripes don't extend around her belly?
This is what we think is a black tipped reef shark. Note how pointy her teeth are, tiger shark's teeth are more triangular and serrated, so that they can saw through things like turtle shell and dugong bone. Do you think this shark could cut through a turtle shell with her teeth? What other differences between her and a tiger shark can you identify? Look up photos of tiger sharks on the internet and tell your teacher!
These are two loggerhead sea turtles. They are only about 15 months old and will be released into the wild soon. They currently live at Ocean Park Sea Aquarium here in Shark Bay, where they were taken to rehabilitate.
This is my other volunteer, Greg, with a smaller tiger shark. Can you estimate how much smaller she is than the first one? Do you see the orange tag in her dorsal fin? Why might we put a tag in the sharks we catch?
If you have answers to my questions or some questions of your own, send us an email or ask your teacher to.
