Trumpetfish are piscivores - which means they eat fish. I thought that their peculiar appearance of standing on their heads was to disguise themselves. I guess in a sense it is, but only because they are waiting for fish to appear and I think they are hiding from the intended meals.
They will hang until a fish appears and then lightening fast they will expand their mouths widely and swallow the fish. When they do, the mouth appears much like a trumpet. Hence the name trumpetfish. . |
