A personal blog from a Canadian Comparative Physiologist. May include topics from Evolutionary Physiology to Conservation Physiology to basic animal physiology. Ramphastos is the genus name of the Toco Toucan, an animal that signifies everything I find fascinating about animal evolution.

Some like it hot...
In theory, I could post a complete thermal image library of Galapagos fauna, but I'm saving that for my big 'coffee table thermal image book' that will make me millions. Meanwhile, here are a few crabs basking/avoiding the sun.
What I find incredible here is how fast things heat up in the sun. These crabs were moving quite a lot, yet you still see how the little bit of shade offered along a rock wall affords them the ability to alter temperature quickly.
You heard it here…anytime someone says that ectotherms/cold blooded animals simply conform to the temperature of their environment you can tell them 'nope'!
Bask away crustaceans. Those of you who like to eat crabs are probably salivating right now.
