Northern Puffer Spheroides maculatus range from Newfoundland to Florida. They feed on all manner of small things, sort of a goat of the ocean. They eat small crustaceans, isopods, amphipods, mollusks, worms, barnacles, bryozoans, sea urchins, sponges, sea anemones and sea squirts, even algae!
As the name implies they are able to do the classic puffing up of their bodies with water. They do this as a defense mechanism which makes them... hopefully to big to eat or two prickly to eat.
