grey whale is descended from creatures that developed 30 million years ago and is the only living species in its genus and family. They were feared by whalers as one of the whale species that would fight back fiercely if hunted. The grey whale was hunted to extinction in the Atlantic Ocean by the early 18th Century, and became endangered in the Pacific until whaling was restricted in the late 20th Century. The biggest remaining population of grey whales migrates along the Pacific Coast between Alaska and Baja California. In May of 2010, a grey whale was sighted off the coast of Israel, leading scientists to believe they may be repopulating areas of the Mediterranean that have not seen these creatures for many centuries.
spiny lobster lacks the large claws of its Atlantic cousin, and is found along the Pacific Coast from Monterey California to the Gulf of Tehuantepec in Mexico. The female can carry up to 680,000 eggs. It lives on sea urchins, mussels, clams, and worms and is in turn hunted by a variety of predators including humans.
Moray's don't see very well with their tiny eyes, and rely on a highly developed sense of smell. They like to hide in rocky crevices and holes waiting for prey to wander by. Morays have large jaws with sharp teeth developed for tearing flesh. They are unusual in having a second set of jaws inside their throats which launch out and grab prey and drag it into the throat. This is probably because, with their narrow necks, they can't swallow prey like other fish. Morays are the only animal that does this. Morays can and do inflict serious injuries on humans. Watch your fingers!
Perrunichthys perruno, and its range is Venezuela and Brazil. It is sometimes known as the leopard catfish, and originates in the Lake Maracaibo, a brackish bay in northern Venezuela connected to the ocean by a narrow channel. It is the largest lake in South America.
Pez Tigre is a favorite of divers because of it's sociability as it interacts with them.
Catsharks, of the family Scyloirhinidae, are sometimes also known as dogfish. They live in temperate and tropical seas and can be found in depths from shallow intertidal waters to 2000 meters (6600 ft.). The ones shown above range in size up to 2.5 meters (8.2 ft.).
