Basking shark. The basking shark ( Cetorhinus maximus) is the second-largest living shark and fish, [4] 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.
Basking shark (Cetorhinus maximus) Second largest species of shark in the world, but this shark is a filter feeder and not a predator. It can be mistaken for the great white owing to similar coloring, but has gill slits that slash almost around its whole head and has a front dorsal fin that is more triangular than the raked shape [12] found in ...
Freshwater shark. Freshwater sharks are sharks able to live in freshwater lakes and rivers, including: the bull shark, Carcharhinus leucas, which can swim between salt and fresh water, and are found in tropical rivers around the world. Some prehistoric sharks (in a broad sense), including hybodonts and xenacanths, are also thought to have ...
Possibly extant (resident) The great white shark ( Carcharodon carcharias ), also known as the white shark, white pointer, or simply great white, is a species of large mackerel shark which can be found in the coastal surface waters of all the major oceans. It is the only known surviving species of its genus Carcharodon.
The megamouth shark (Megachasma pelagios) is a species of deepwater shark. Rarely seen by humans, it measures around 5.2 m (17 ft) long and is the smallest of the three extant filter-feeding sharks alongside the relatively larger whale shark and basking shark. Since its discovery in 1976, fewer than 100 specimens have been observed or caught.
Sharks are very frequently overfed by amateur aquarists, which can lead to obesity or unnaturally fast growth rates. [7] Captive sharks are healthiest when fed at levels similar to their food intake in the wild. [7] Usually this amounts to 1-3% of their body weight weekly. [7] However, aquarium conditions and species disposition are considered ...
The last sighting of a live basking shark was in 2012, although the species used to be "very common" in New Zealand waters during the mid-late 1990s. The basking shark is the second-largest fish ...
They generally do not live in fresh water, with a few exceptions such as the bull shark and the river shark which can swim both in seawater and freshwater. Sharks are common down to depths of 2,000 metres (7,000 ft), and some live even deeper, but they are almost entirely absent below 3,000 metres (10,000 ft).
