Most light-producing fish live in mid-water or are bottom-dwelling deep sea species. "A small gene pool can lead to inbreeding and poor health, which is sometimes seen in endangered species," says lead author Dr Catherine Attard, from Flinders University's Molecular Ecology Lab. It is starvation and starvation until it is attracted by the aroma of a womans pheromones. A fish has many .

By ingesting food and absorbing necessary salts in places such as the gills, fish actively take in enough to replace what's lost in urine. Its one of the proofs that natural selection does happen. At the bottom of the Mariana Trench there is 1,086 bars of pressure, the equivalent of 100 elephants standing on your head, according to Abbie Chapman, a researcher at University College London who has studied creatures living around hydrothermal vents. This allows the organism to resist the extreme pressure it is under. The goldfish in your aquarium may be producing a third or its body weight as urine every day [3].
