Overall length. Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. This measurement excludes the length of the caudal (tail) fin. [1] Total and fork length of a fish. Total length (TL) is the length of a ...
Standard weight equation for largemouth bass [1] and burbot [2] (fish). Standard weight in fish is the typical or expected weight at a given total length for a specific species of fish. Most standard weight equations are for freshwater fish species. Weight-length curves are developed by weighing and measuring samples of fish from the population.
The largest fish of the now-extinct class Placodermi was the giant predatory Dunkleosteus. The largest and most well known species was D. terrelli, which grew almost 9 m (29.5 ft) in length [21] and 4 t (4.4 short tons) [22] in weight. Its filter feeding relative, Titanichthys, may have rivaled it in size. [23]

The world's smallest fish depends on the measurement used. [1]Based on minimum standard length at maturity the main contenders are Paedocypris progenetica where females can reach it at 7.9 mm (0.31 in), [2] [3] [4] the stout infantfish (Schindleria brevipinguis) where females reach it at 7 mm (0.28 in) and males at 6.5 mm (0.26 in), [1] and Photocorynus spiniceps where males can reach it at 6. ...
It eats mainly fish and frogs, but also small mammals and birds fall prey to pike. Young pike have been found dead from choking on a pike of a similar size, an observation referred to by the renowned English poet Ted Hughes in his famous poem "Pike". [29] Northern pike also feed on insects, crayfish, and leeches. [30]
This fish was first described in 1758 as Mullus barbatus by the Swedish zoologist ... The red mullet can grow to a standard length of 30 cm (12 in), but a more common ...
