Many smaller wrasses follow the feeding trails of larger fish, picking up invertebrates disturbed by their passing.
Most wrasses inhabit the tropical and subtropical waters of the Atlantic, Indian, and Pacific Oceans, though some species live in temperate waters: the Ballan wrasse is found as far north as Norway. Juveniles are a mix of males and females (known as initial phase individuals), but the largest adults become territory-holding (terminal phase) males.
and live in sheltered areas such as seagrass beds, estuaries, coral reefs, or mangroves. Colonies have been found in European waters such as the Thames Estuary. They swim upright propelling themselves by using the dorsal fin.
Four species are found in Pacific waters from North America to South America. The pectoral fins located on either side of the head are used for maneuvering. Their prehensile tail can only be unlocked in the most extreme conditions.
These species form territories; males stay within 1 m They are named for their equine appearance with bent necks and long snouted heads followed by their distinctive trunk and tail.
They are adept at camouflage with the ability to grow and reabsorb spiny appendages depending on their habitat.
Monterey Bay is the seasonal home to adult white sharks, which return to California in late summer and early fall after spending months offshore in waters as far west as Hawaii.
The sharks gather to feed when naïve juvenile elephant seals assemble together and haul out in colonies along the Central Coast.
The nasal and mandibular bones are connected at their posterior ends to the rigid neurocranium, and the superior and inferior articulations of the maxilla are joined to the anterior tips of these two bones, respectively, creating a loop of four rigid bones connected by moving joints.Fish (plural: fish or fishes) are vertebrates which live in water and respire (get oxygen) with gills. This is a definition which does not quite work: some amphibia also live in water and have external gills, but they are not fishes. Now the term covers five classes of aquatic vertebrates: Fish are usually covered with scales.They have two sets of paired fins and several unpaired fins. A fish takes in the oxygen from the water using gills. They live in fresh water in lakes and rivers, and in salt water in the ocean. The largest fish is the whale shark, which can be almost 15 meters long and weigh 15 tons. A group of fish called the lungfish have developed lungs because they live in rivers and pools which dry up in certain parts of the year.Fish is used either as singular noun or to describe a group of specimens from a single species. Certain animals that have the word fish in their name are not really fish: Crayfish are crustaceans, and jellyfish are Cnidarians. Teleosts ('modern' fish) have what are called leptoid scales.These grow in concentric circles and overlap in a head to tail direction like roof tiles.
