Why do beluga whales have love handles?
J Thoendell stashed this in Science
Unlike many dolphins and whales, belugas lack a dorsal fin. Maybe it’s too cold to have blood running through such a thin exposed surface, or maybe it’s too dangerous to swim under ice with a dorsal fin. Whatever the reason, belugas are apparently making up for this absence with fat. Getting ready for a risky maneuver? Time to pooch the paunch. In the ever changing ice flows these whales call home, the extra stability these love handles provide may mean the difference between a clean getaway and a collision with an iceberg.
I never thought of the extra stability or lack of dorsal fin.
I always figured it was extra insulation.
