A similar strategy has been employed by fish in the presence of large reef sharks, as they use the larger animal as a tool to ambush prey. [46] The opportunistic nature of giant trevally has also been made evident by studies on the mortality rate of undersized or egg-bearing lobsters released from traps at the water's surface of the Hawaiian ...

As eels migrate long distances, overfishing and pollution in one location may endanger the population and little is known of all possible causes for the diminishing population. [4] The eel is a popular dish, especially in southern Sweden, and is economically of importance with catches of around 1,000 tonnes (1,200 in 1983).
Fish of the order are found in oceans worldwide, at depths from 120 to 4,900 metres (390 to 16,080 ft). They are elongated fish, although not as much so as the true eels , and have various feeding strategies, like hyperbenthic and detritus feeders, epifaunal browsers, and megafaunal croppers. [ 3 ]
