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
The avocet is a type of wading bird that is found across mudflats in the world's warmer climates. There are four different species of avocet which are the Pied avocet, the American avocet, the Red-necked avocet and the Andean avocet.
The avocet is generally found in watery habitats close to the coast including marshland, wetlands and swamp. The exact habitat of the avocet is dependent on the species as the Pied avocet is found in Europe and Asia, the American avocet is found on the Pacific coast of North America, the Red-necked avocet in Australia and the Andean avocet is natively found nesting high up in the Andes Mountains.
The avocet is a very distinctive looking bird due to t

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
