Question 499Navigation General

The correct answer is D) All of the above. Northern right whales can be identified by the following characteristics: 1) A "V" shaped blow that is easily visible from ahead or behind the whale. 2) Whitish patches of skin on the top of the head, called callosities. 3) The absence of a dorsal fin on the back. These three distinctive features make northern right whales easily recognizable and differentiate them from other whale species, which is why all of the answer choices are correct. The other options are not complete on their own, as they only describe one or two of the key identifying traits.
