I concur with Yaipen-Llanos. There are three very evident ridges in the rostrum, typical of Bryde's whale. There are no bumps or tubercles on the head and the flipper -pectoral fin- is not particularly long (as in humpback whales). Blue whales have only one ridge in the head (as most Balaenopterid whales). This is a tropical area with relatively warm waters, right?
