The latest casualty is a 12-metre Bruda whale weighing about two tonnes washed ashore in Village 9 of Tambon Thongchai, Bang Saphan district of Prachuab Khiri Khan.
Thorn said that this latest Bruda whale which was not an aging whale appeared to have died from unnatural cause – an indicative that there was something wrong with the sea.
Earlier, one six-month old Bruda whale was found dead on the beach of Ban Kung Tanod in Tambon Khao Daeng, Kui Buri district of Prachuab Khiri Khan.
Two whale sharks which died in the Gulf and washed ashore in the past 70 days were entangled in ropes.
Since there are an estimated 100 whale sharks and about 50 Bruda whales in the Gulf of Thailand, Thorn said the deaths of two whale sharks and two Bruda whale in just 70 days were indeed a big shock.
