According to fossil records, they have been on Earth for more than 500 million years! The total number of living fish species-about 32,000- is greater than the total of all other vertebrate species (amphibians, reptiles, birds, and mammals) combined. Another is that fish are very old on the evolutionary scale. The animals in this group live in a variety of habitats ranging from coral reefs and kelp forests to rivers, streams, and the open ocean. One reason fish are so diverse is that 70 percent of the planet is covered in water. Others can find their prey and even navigate by detecting electrical charges. The rare fish, with a mouthful of molars that resemble that of a sheep (or even a human), was caught by Nathan Martin, a regular on the pier who had been hoping to land one. It shows the fish having incisors on the upper and lower jaws. Many can detect motion in the water using a special row of scales with sensors known as the lateral line. Meet the sheepshead fish, a rare ocean creature with a mouthful of molars and possibly the only thing in the sea with a dental plan. An image of the aquatic animal shared on the Facebook page has instantly gone viral and surprised many.

Some species, such as the weedy sea dragon, are so bizarre they seem almost unreal.įish have developed special senses, too. Whale sharks, the largest fish, give birth to live young and eat only tiny fish, squid, and plankton. The high season for Fluke is April and May Bluefish, Porgy, Cod, and Ling come into season in late Summer and are available all through the Fall months and until the. Striped Bass come into season in June and are present until Fall. Eels, by contrast, have worm-like bodies and exceedingly slimy skin. Sheepshead Bay offers the chance of targeting a variety of fish species to be caught throughout the year. Fin fish like salmon have gills, are covered in scales, and reproduce by laying eggs. All fish share two traits: they live in water and they have a backbone-they are vertebrates.Īpart from these similarities, however, many of the species in this group differ markedly from one another.
