Saw one (perhaps two on two different occasions), off Gladden Spit, locally known as the Elbow, 17 miles out from the town of Placencia. He was about twenty feet long. They have huge heads, graceful tapering bodies, huge tails. They are dark grey with white spots. This guy was somewhat curious, and veered rather close at times.
He was impressive, slow, and conscious of his size–like a senator. But he seemed neither arrogant nor timid, unlike a senator.
