The fishes of the order Syngnathiformes (pipefishes, seahorses, and trumpetfishes) are some of the most visually bizarre and strangely adapted fishes on our planet and yet most of them look downright conventional when compared to those members of the family that look more like plants than fish. In what is certainly a textbook case of mimicry, the weedy and leafy seadragons have evolved to look like the kelp and seaweed fronds they live amongst.
