It is of commercial importance as a food fish in its native range. [2] In addition to being fished, it may be threatened by siltation from deforestation and agricultural activities, pollution and habitat change by hydropower and dam development. The exact population is unknown. It spawns once during the rainy season from May–July. [1]
The electric rays are a group of rays, flattened cartilaginous fish with enlarged pectoral fins, composing the order Torpediniformes / t ɔːr ˈ p ɛ d ɪ n ɪ f ɔːr m iː z /.They are known for being capable of producing an electric discharge, ranging from 8 to 220 volts, depending on species, used to stun prey and for defense.

Fish are first speared and the snake-like neck emerges above the water to toss and swallow the fish head-first. The Oriental darter is like all other anhingas, a cormorant-like species that has a very long neck. The structure of the neck is as in other species of darter with strongly developed muscles about a kink in the neck at the 8th and 9th ...

Needlefish (family Belonidae) or long toms [2] are piscivorous fishes primarily associated with very shallow marine habitats or the surface of the open sea. Some genera include species found in marine, brackish, and freshwater environments (e.g., Strongylura), while a few genera are confined to freshwater rivers and streams, including Belonion, Potamorrhaphis, and Xenentodon.

Slimeheads store energy as extracellular wax esters, which aid the fish in maintaining neutral buoyancy. Slimehead behaviour is not well studied, but some species sporadically form dense aggregations. In the case of the orange roughy, these aggregations (possibly segregated according to sex) may reach a population density of 2.5/m 2;.
Ogcocephalidae is a family of anglerfish specifically adapted for a benthic lifestyle of crawling about on the seafloor. Ogcocephalid anglerfish are sometimes referred to as batfishes, [1] [2] deep-sea batfishes, [3] handfishes, and seabats. [4]
