Several studies conducted on the species' diet over its range have found other aspects of its diet vary widely, including the specific types of prey the species takes and the change in diet with age. The most detailed of these studies was conducted in the Southern USA, which showed the species diet comprised between 74% and 94% fish. [27]
Common names of fish can refer to a single species; to an entire group of species, such as a genus or family; or to multiple unrelated species or groups. Ambiguous common names are accompanied by their possible meanings. Scientific names for individual species and higher taxa are included in parentheses.
Jack mackerel caught by a Chilean purse seiner Fishing down the food web. Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area.
More than 1100 species of fish [33] have been recorded in the Red Sea, and around 10% of these are found nowhere else. [34] This also includes around 75 species of deepwater fish . [ 33 ] The rich diversity is in part due to the 2,000 km (1,240 mi) of coral reef extending along its coastline ; these fringing reefs are 5000–7000 years old and ...
Morchella species have been called by many local names; some of the more colorful include dryland fish, because when sliced lengthwise then breaded and fried, their outline resembles the shape of a fish; [92] hickory chickens, as they are known in many parts of Kentucky; and merkels or miracles, based on folklore, of how a mountain family was ...
Oil has not been shipped in barrels [29] since the introduction of oil tankers, but the 42 US gallon size is still used as a unit of measurement for pricing and tax and regulatory codes. Each barrel is refined into about 20 US gallons (17 imp gal; 76 L) of gasoline , [ 30 ] the rest becoming other products such as jet fuel and heating oil ...
The level of wax esters in the spermaceti organ increases with the age of the whale: 38–51% in calves, 58–87% in adult females, and 71–94% in adult males. [4] Spermaceti wax is extracted from sperm oil by crystallisation at 6 °C (43 °F), when treated by pressure and a chemical solution of caustic alkali. Spermaceti forms brilliant white ...
The 67,000 described species range in size from Stygotantulus stocki at 0.1 mm (0.004 in), to the Japanese spider crab with a leg span of up to 3.8 m (12.5 ft) and a mass of 20 kg (44 lb). Like other arthropods , crustaceans have an exoskeleton , which they moult to grow.
