Mother turtles find their way back to nesting beaches by looking for unique magnetic signatures along the coast, according to a new study published in Current Biology.

Strange marine animals found around the Canary Islands

Marine conservation group Oceana finds amazing array of marine life in Canary Islands expedition, from shallows to down to 1000m. Using ROVs (remotely operated underwater vehicles) as well as scuba divers to shallow depths, they documented large colonies of deep-sea white coral, crystal aggregations of sponges, dense forests of black corals, oceanic puffers, giant foraminifera, carnivorous sponges and sharks, as well as many other biological communities and species in the south of the El Hierro Island.
