Yes, they blow up. At least in rare cases.
I came across this article while reading about explosives, and saw a link that said "Exploding Animals". Had to check it out.
Some Whales explode after being washed up on the beach, due to build up of methane gases in their body caused by the bacteria that decompose them. A species of Ants has a function where it tenses up and "blows open" its body, expelling a bunch of disgusting chemicals.
But the most interesting thing I read in the article was about the exploding toads. They usually puff themselves up with air to make themselves look bigger as a defense mechanism, which usually is effective. But their predators happen to be some of the smartest animals on the plant: Crows. After an influx of predatory crows in the area, around 1,000 toads died by blowing themselves up. Berlin veterinarian Franz Mutschmann proposed a theory as to why this was happening. After observing the behavior of Crows in the area, he proposed that the Crows figured out how to make the toads do this. You see, the toads will keep puffing themselves up until a threat is no longer present. So apparently, the Crows taunt the toads until they take in too much air and then pop them like a balloon, resulting in an easy kill. Oh, and the toads actually live for a short amount of time after the explosion.
I've heard of a similar sensation happening to Puffer Fish, but this seems more odd.
Am I a bad person for laughing at this?
