SEA Shepherd activists have rescued a number of crew who abandoned an alleged poaching vessel that has now sunk off the West African coast.
Some Thunder crew members are now onboard a Sea Shepherd ship, the Sam Simon, while others remain in life boats.

Another of the group's ships, the Bob Barker, had been tailing the Thunder boat for several months and received a distress call from the vessel early on Monday.
Bob Barker captain Peter Hammarstedt said the activists will give evidence of illegal poaching activities to Interpol.
They expect to reach an island port in the Gulf of Guinea today.
