scientists from james cook university have discovered two critically endangered species of sea snakes, 1 thought to be extinct, off the coast of western australia. it's the first time the snakes have been 2 alive and healthy since disappearing from their only known habitat on ashmore reef in the timor sea more than fifteen years ago.
 
"this discovery is really exciting, we get another chance to protect these two endemic western australian sea snake species," says study lead author blanche d'anastasi from the arc centre of 3 for coral reef studies at jcu.
 
"but in order to succeed in protecting them, we will need to monitor populations as well as undertake research into understanding their biology and the threats they face".
 
the discovery of the critically endangered short nose sea snake was confirmed after a western australia parks and wildlife officer, grant griffin, sent a photo of a pair of snakes taken on ningaloo reef to ms d'anastasi for identification.
 
 "we were blown away, these potentially extinct snakes were there in plain sight, living on one of australia's natural 4, ningaloo reef," says ms d'anastasi.
 
"what is even more exciting is that they were courting, suggesting that they are members of a breeding population." 
 
the researchers also made another unexpected discovery, uncovering a significant population of the rare leaf scaled sea snake in the lush seagrass beds of shark bay. 
 
the discovery was made 1700 kilometres south of the snakes only known habitat on ashmore reef.
 
 "we had thought that this species of sea snake was only found on tropical coral reefs. finding them in seagrass beds at shark bay was a real surprise," says ms d'anastasi.
