What do Sharks Eat? Everything!

We love the Academy of Sciences in Golden Gate Park. It has a planetarium, an indoor rain forest, and a wonderful underground aquarium with fish from all over the world.

The living fish exhibits are terrific, but this display really got our attention.

Most sharks go after food that is easiest to catch, like slow, weak or dying marine animals. Sharks use their teeth to grab and tear their prey, but they don’t chew it up and usually swallow it almost whole. Many species of shark are bottom feeders, meaning they literally scoop up food from the bottom of the ocean. According to, tiger sharks are the “garbage cans of the sea” because they will eat whatever is available. From the looks of this picture, we’d say that was a good description!

Awesome Underwater Volcano


From our friends at’s “The Big Picture” come these awesome photos of an undersea volcano erupting.

This eruption took place this week and was accompanied by a strong earthquake. It happened near the island nation of Tonga, located in the South Pacific.
