Porcupinefish - Porcupinefish Porcupinefish are fish of the family Diodontidae (order Tetraodontiformes). (Full-size image) They have the ability to blow themselves up by swallowing water or air when threatened. They are covered by long spines that stick out sharply when the fish is inflated. The porcupinefish is closely related to the pufferfish, which does not have spines..
Pufferfish - several times its normal size by swallowing water or air when threatened. The same adaptation is found in the related porcupinefish, which also have spines. Pufferfish accumulate the poison Tetrodotoxin from a symbiotic bacterium, which makes them highly poisonous even to humans. Despite this they are prized as a delicacy in Japan, where fugu (河豚 or フグ) is carefully prepared by removing the poisonous skin and organs and served as sushi or sashimi, or cooked in broth. In recent years, most fugu is produced from farmed pufferfish, where the bacterium is rare, and so the resulting fish are generally not poisonous. Apparently due to some unknown selection pressure, intronic and extragenic sequences have been drastically reduced within this family. As a result they have the smallest known genomes among the vertebrates,.
