Do blue whales reach the theoretical size limit for a vertebrate?
In other words, do blue whales the largest vertebrate animals can ever get?
Base on some of my understanding about bone, tissues and thermal regulation, I feel that Blue Whales had already pushed the parameters to the limit. If there exist an animal bigger, either their bones can't handle the weight, or the tissues can't contain their internal pressure or inadequate thermal regulation cooks the animals from the inside. #science source
