Catfish are a group of bottom-feeding fish that are found in freshwater habitats and coastal regions on and around every continent in the world with the exception of Antarctica. Catfish are most easily identified by their flattened broad heads and the long whisker-like barbels that protrude from the mouth of the catfish.
The long barbels of the catfish contain the taste buds of the catfish and so are often most commonly used for smelling and therefore sensing what is about to eat (and to hide from) in the surrounding waters. Despite the name however, not all catfish species have prominent whisker-like barbels.
There are nearly 3,000 known species of catfish in the world but it is
The Giraffe is a long-necked, hoofed mammal that is natively found grazing in the open woodlands of sub-Saharan Africa. The Giraffe is the tallest living animal on land and despite it's height is mostly closely related to the much smaller and solitary Okapi, that is found elusively dwelling in the dense tropical forests. There are nine recognised sub-species of Giraffe that are found in differing geographic locations and vary somewhat in the colour and pattern of their spot-like markings. Although the Giraffe would have once been found across sub-Saharan Africa and even in parts of North Africa, today they are extinct from much of their historically vast natural range with only small, isolat

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
