An average adult channel catfish measures at least 12 inches (30 centimeters) long, and weighs between 2 and 4 pounds. The largest specimen on record weighed 58 pounds and was caught in 1964 by an angler in South Carolina. [16] As channel catfish grow longer, their weight increases. The relationship between length and weight is not linear.
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.
These coastal reefs are also visited by pelagic species of red sea fish, including some of the 44 species of shark. Approximately 40% of the Red Sea is quite shallow (under 100 m/330 ft), and about 25% is under 50 m (164 ft) deep. About 15% of the Red Sea is over 1,000 m (3,300 ft) depth that forms the deep axial trough.
E. dofleini is distinguished from other species by its large size. It is the largest octopus species. [4] [5] [12] Adults usually weigh around 15 kg (33 lb), with an arm span up to 4.3 m (14 ft). [13] Some larger individuals have weighed in at 50 kg (110 lb), with a radial span of 6 m (20 ft). [3]
The medusae of most species are fast-growing, and mature within a few months then die soon after breeding, but the polyp stage, attached to the seabed, may be much more long-lived. Jellyfish have been in existence for at least 500 million years, [1] and possibly 700 million years or more, making them the oldest multi-organ animal group. [2]
The penis size of fin whales typically reaches a length of 1.3 m (4 ft 3 in); the testes usually weigh 1–3 kg (2.2–6.6 lb) in mature individuals. [ 40 ] [ 41 ] The oral cavity of the fin whale has a very stretchy or extensible nerve system which aids them in feeding.
1 tonne (1.1 short tons) The sperm whale is the largest toothed whale and is among the most sexually dimorphic of all cetaceans . [ 35 ] Both sexes are about the same size at birth, [ 11 ] but mature males are typically 30% to 50% longer and three times as massive as females.
Takifugu, also known by the Japanese name fugu (河豚, lit. "river pig"), is a genus of pufferfish with 25 species, most of which are native to salt and brackish waters of the northwest Pacific, but a few species are found in freshwater in Asia or more widely in the Indo-Pacific region.
