THE PRINCE OF WHALES: BLAINVILLE’S BEAKED WHALES IN ABACO
There’s a strange affinity between humans and whales. Humans seem to think so, anyway – and whales seem to tolerate them amiably, perhaps now that the decimation of their populations by humans is (largely) a thing of the past. The Bahamas in general and Abaco in particular are in the mainstream of progressive cetacean research, led by the BMMRO at Sandy Point.
One of the speciality research species is the Blainville’s Beaked Whale. These magnificent creatures are deep divers, and although they are found in many parts of the world, the Bahamas is one of only 3 locations with a significant population for study. Most of the whales here were photographed within sight of land (and a few with the Castaway Island Disney Cruise Ship visible on the horizon!).
I’ve been lucky enough to be on the BMMRO research vessel on a beaked whale outing – and luckier still that we were able to spend plenty of time with a group of them, including some males. The header image is of a mature male with his huge teeth that protrude upwards from the lower jaw, and in time become encrusted with barnacles.
The whales were quite undisturbed by our presence – indeed they behaved much like dolphins, circling the boat and swimming under it; moving away and returning. This was an opportunity to count the whales, to identify those that had already been recorded, and to document any new ones. Each whale has its own unique pattern of marks, striations and in some cases healed wounds. The pair below are a good example.
Also, the whales have individually distinctive dorsal fins, with nicks and tears that also act as a means of identification. These can often be made out from a distance with powerful binoculars or photographed with a long lens for later analysis (this ID method also works reliably for dolphins).
Beaked whales often bear the healed scars from the gouging bites of COOKIE-CUTTER SHARKS, a vicious little species that I recently featured. The distinctive circular scars on the back of the whale below result from encounters with these unpleasant creatures.
Finally, the photo below. It has no merit, photographically speaking, but I love the way that sometimes a ‘risk’ shot – into the sun, perhaps – produces rather magical effects. The unexpected ‘sea stars’ were a bonus!
