An opportunistic species which preys on a wide range of food.

Some may overwinter in the deeper waters of the Gulf of St. They spend most of their time at the surface, hence their nickname the "sun fish." When the sharks are fed in Ocean Voyager, they employ this suction-type feeding style, while following feeding ladles along the surface , e.g. The Atlantic salmon download here.

This derives from dinoflagellates contaminating shellfish (clams, scallops, oysters, etc.). The toxin, saxotoxin, is water soluble, heat and base stabile, and is therefore not affected by steaming or cooking. It inhibits sodium channels of excitable membranes, blocking propagation of nerve and muscle action potentials download. They occur, there, in pods of ten or twenty, and it has been estimated that total number there, in the waters, is MORE THAN 200. This apparently is due to the swirling waters where the Gulf of Mexico meets the Atlantic Ocean. Those waters teem with plankton, noted as the Whale Shark's favored food. The highest number of Whale Sharks off the northern Yucatan Peninsula is said to be in the summer, although it does occur at other times Fish Bioacoustics (Springer Handbook of Auditory Research) Fish Bioacoustics (Springer Handbook of. Highest cumulative impacts are localized in a few key areas on the Scotian Shelf in the Bay of Fundy and Gulf of Maine.

The spear, which stiffens when the stingray feels threatened, is serrated like a steak knife and packs a venom that can be deadly to predators. "The venom itself is a largely protein-based toxin that causes great pain in mammals and may also alter heart rate and respiration," according to the Mote Marine Laboratory Who Cares About Wildlife Social Science Concepts for Exploring Human-Wildlife Relationships and Conservation Issues.jpg Why?
