A gigantic, ancient relative of the newt, a drawing-pin sized frog, a limbless, tentacled amphibian and a blind see-through salamander have all made it onto a list of the world’s weirdest and most endangered creatures.
ZSL EDGE programme is highlighting some of the world’s most extraordinary creatures currently threatened with extinction. This year ZSL scientists have assessed all amphibian species according to how Evolutionarily Distinct and Globally Endangered (EDGE) they are.
“The EDGE amphibians are amongst the most remarkable and unusual species on the planet and yet an alarming 85% of the top 100 are receiving little or no conservation attention and will become extinct if action is not taken now.” Helen Meredith, EDGE Amphibians coordinator, commented. “These animals may not be cute and cuddly, but hopefully their weird looks and bizarre behaviours will inspire people to support their conservation.”
ZSL has identified and is starting work to protect ten of the most unusual and threatened EDGE amphibian species this year, including:
Dr Jonathan Baillie, Head of the EDGE programme, commented, “Tragically, amphibians tend to be the overlooked members of the animal kingdom, even though one in every three amphibian species is currently threatened with extinction, a far higher proportion than that of bird or mammal species. These species are the “canaries in the coalmine” – they are highly sensitive to factors such as climate change and pollution, which lead to extinction, and are a stark warning of things to come. If we lose them, other species will inevitably follow. The EDGE programme strives to protect the world’s forgotten species and ensure that the weirdest species survive the current extinction crisis and astound future generations with their extraordinary uniqueness.”
EDGE (Evolutionarily Distinct and Globally Endangered) animals are those with few close relatives and are highly distinct genetically. These animals are also extremely endangered and desperately in need of immediate action to save them from becoming extinct. By mathematically combining a measure of each species’ unique evolutionary history with its threat of extinction, the scientists are able to give species an EDGE value and rank them accordingly. In January 2007, the EDGE team assessed all mammal species and released the list of the top 100 EDGE mammal species. The scientists have now done the same for all amphibian species (frogs, salamanders and caecilians) and have found that 85 of the top 100 are receiving little or no conservation attention.
Amphibians are declining as a result of a range threats including habitat destruction, pollution, climate change and disease. Scientists at the Zoological Society of London (ZSL) are currently researching the diseases affecting amphibians, with particular focus on the chytrid fungus, which is implicated in mass mortality events globally.
