The mayfly is medium-sized insect that is found in a variety of habitats all around the world. The mayfly is one of the most short-lived animals in the world and is most closely related to dragonflies and damselflies.
There are 2,500 known species of mayfly generally found close to water, all around the world with over 600 species of mayfly natively found in North America. Mayflies are extremely sensitive to pollution and can therefore only be found close to water that is of a high quality.
Mayflies have long narrow bodies and large wings, with a second set of smaller hind wings behind them (in a similar way to butterflies and moths). This allows the mayfly to have greater agilit

Bycatch is the most critical extinction threat facing marine megafauna in coastal seas, including the world's most endangered dolphins, porpoises, seals, dugongs, sharks, and marine turtles. These vulnerable species share coastal waters with small-scale fisheries that employ 99% of the world's 50 million fishers. An estimate of global dolphin and porpoise bycatch indicates that more than 300,000 individuals are killed each year, with about 98% resulting from entanglement in gillnets and about 2% in trawlers and other gear, such as long lines.
A global review of marine mammal consumption by humans concluded that targeted hunts of small cetaceans have generally been reduced and capture
