I think I can get away with claiming this belongs in my blog under the “Nature” category. A previous post (Roatan) was fairly popular so thought I would share a bit more. Many of these photos were provided by Anthony’s Key/Roatan Institute for Marine Science or professional photographers.
There are many different species of dolphins – those shown here weigh upwards of 400lbs (they are larger than porpoises). We love them for their intelligence, their often friendly appearance (that “smile” of theirs) and their playfulness.
Like whales and porpoises they are mammals. As a matter of fact – here’s the interesting bit – they are descended from land mammals! We knew mammals came out of the water way back in geologic time, but here is a mammal whose ancestors (re)entered the seas roughly 50 million years ago.
Dolphins communicate with whistle-like sounds as well as clicks for echolocation.
I’m toying with the idea of a marine biologist as a character in my next novel. What do you think? (In the recent one, the protagonist was a rain forest biologist and her lover was a geologist – they made an interesting couple.)
