This Striped Puffer, a fish of the illustrious family Tetraodontidae, was filmed in the Philippines at about 25 feet depth.  Like other members of the Tetraodontidae, the Striped Puffer has a powerful neurotoxin, tetrodotoxin,  which causes other fish to avoid eating it.  Indeed, members fo this family are among the most poisonous of all creatures on the planet. Because of the poison it contains, the fish can swim slowly around bottoms and coral reefs.  Interesting how evolution finds a way!

This clip is particularly interesting to me personally, as it shows some sort of feeding behavior.  If you watch it closely, you will see the fish take something into its mouth, and then forcefully spit it out.  It does this two or three times.
