The minnow family (which includes carp), Cyprinidae, is the largest family of vertebrates, with over 2400 species known today. [90] The largest species is the giant barb (Catlocarpio siamensis), which is endemic to three river basins in southeast Asia and reaches a size of as much as 3 m (9.8 ft) and a weight of as much as 300 kg (660 lb).

Among the cyprinids, only the golden mahseer can reach a comparable length, but it is a relatively slender fish that weighs far less. [6] Few large giant barbs are caught today. For example, no individual weighing more than 150 kg (330 lb) has been caught in Cambodia since 1994. [1] Today, the maximum length is about 1.8 m (6 ft).
Orcas — also known as killer whales — are once again on the offensive. Their new target is whale sharks, the world's largest fish species. According to CNN, a new study — published in the ...
The vast majority of extant fish are members of Osteichthyes, being an extremely diverse and abundant group consisting of 45 orders, over 435 families and 28,000 species. [3] It is the largest class of vertebrates in existence today, encompassing most aquatic vertebrates, as well as all semi-aquatic and terrestrial vertebrates.
Moctezuma, who was first spotted in 1992, has been seen hunting other elasmobranch species such as the Munk’s pygmy devil ray, which is 1 meter (3.2 feet) wide, bull sharks and stingrays.
The Great Barrier Reef is the world's largest structure composed of living entities, stretching 2,000 km (1,200 mi) but contains many organisms of many types of species. When considering singular entities, the largest organisms are clonal colonies which can spread over large areas.
A fisherman in northern Cambodia hooked what researchers say is the world’s largest freshwater fish — a giant stingray that scientists know relatively little
Most oceanic species (78 per cent, or 44 per cent of all fish species), live near the shoreline. These coastal fish live on or above the relatively shallow continental shelf. Only 13 per cent of all fish species live in the open ocean, off the shelf. Of these, 1 per cent are epipelagic, 5 per cent are pelagic, and 7 per cent are deep water. [16]
