Scientists working on the Ashmore Reef in Western Australia were the first humans to see a short-nosed sea snake in more than two decades last week. The reptiles, which are olive-colored and highly endangered, have been considered extinct in the region for 23 years.

Deadly Sea Snake

According to Sanders, the position indicates one of two scenarios. In the first case, the original short-nosed sea snakes have been living on the coral for a long time, at distances outside human control. The coastal snakes have simply extended their territories in the second.

"Is it possible that they recolonized from the coast? That is an extremely significant issue," Sanders stated his opinion. "If the coastal population recolonizes, it suggests that we've missed the historical richness that used to exist on Ashmore."

Testings will soon be conducted.
