Salmon sharkThe salmon shark (Lamna ditropis) is a species of mackerel shark found in the northern Pacific ocean. Similar to other mackerel sharks, salmon sharks have a thunniform body type. As an apex predator, the salmon shark feeds on salmon, squid, sablefish, birds, walleye pollock, and herring. Salmon sharks get their name from their diet, which primarily consists of salmon. It is known for its ability to maintain stomach temperature (homeothermy), which is unusual among fish.
Basking sharkThe basking shark (Cetorhinus maximus) is the second-largest living shark and fish, after the whale shark. It is one of three plankton-eating shark species, along with the whale shark and megamouth shark. Typically, basking sharks reach 7.9 m (26 ft) in length, but large individuals have been known to grow more than 10 m (33 ft) long. It is usually greyish-brown, with mottled skin, with the inside of the mouth being white in colour.
Whale sharkThe whale shark (Rhincodon typus) is a slow-moving, filter-feedingcarpet shark and the largest known extantfishspecies. An individual with a length of 18.8 m (61.7 ft) has been considered the largest reliably recorded. The whale shark holds many records for size in the animal kingdom, most notably being by far the largest living non-cetacean animal.
SharkSharks are a group of elasmobranchcartilaginous fishes characterized by a riblessendoskeleton, dermal denticles, five to seven gill slits on each side, and pectoral fins that are not fused to the head. Modern sharks are classified within the divisionSelachii and are the sister group to the Batomorphi (rays and skates).
PorbeagleThe porbeagle or porbeagle shark (Lamna nasus) is a species of mackerel shark in the familyLamnidae, distributed widely in the cold and temperate marine waters of the North Atlantic and Southern Hemisphere. In the North Pacific, its ecological equivalent is the closely related salmon shark (L. ditropis).
Mako sharkMako sharks are predatory mackerel sharks of the genusIsurus (meaning "equal tail"). They are largely pelagic, and are fast, predatory fish capable of swimming at speeds of up to 50 km/h (31 mph). The two species of mako sharks are sexually dimorphic, with females being larger than males, and are large sharks. Both species are classified as "Endangered" by the IUCN. Two species of mako shark currently exist: The shortfin mako shark, and the longfin mako shark.
FishA fish is an aquatic, anamniotic, gill-bearing vertebrateanimal with a tough cranium to protect the brain, but lacking limbs with digits. Fish can be grouped into the more basaljawless fish and the more common jawed fish, the latter including all livingcartilaginous and bony fish, as well as the extinct placoderms and acanthodians.
EndothermAn endotherm (from Greekἔνδονendon "within" and θέρμηthermē "heat") is an organism that maintains its body at a metabolically favorable temperature, largely by the use of heat released by its internal bodily functions instead of relying almost purely on ambient heat.
LiverVertebrate organ involved in metabolismThe liver is a major metabolicorgan exclusively found in vertebrates which performs many essential biological functions, such as detoxification of the organism and the synthesis of various proteins and other biochemicals necessary for digestion and growth. In humans, it is located in the right upper quadrant of the abdomen, below the diaphragm and mostly shielded by the lower right rib cage.
Temperate climateIn geography, the temperate climates of Earth occur in the middle latitudes (approximately 23.5° to 66.5° N/S of the Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small; they usually differ only in the amount of precipitation.Pelagic zoneThe pelagic zone consists of the water column of the open ocean and can be further divided into regions by depth. The word pelagic is derived from Ancient Greek πέλαγος (pélagos) 'open sea'. The pelagic zone can be thought of as an imaginary cylinder or water column between the surface of the sea and the bottom.
SerrationSerration is a saw-like appearance or a row of sharp or tooth-like projections. A serrated cutting edge has many small points of contact with the material being cut. By having less contact area than a smooth blade or other edge, the applied pressure at each point of contact is greater, and the points of contact are at a sharper angle to the material being cut.
