This relative of the seahorse (Hippocampus) is an excellent mimic of the kelp seaweed. This specimen was washed onto the beach in NSW and I framed it with a seahorse and a pipefish
Southern half of Australia in kelp forests. Found washed up on the beach beside the Wollongong lighthouse
Whereas male seahorses hold their young in a pouch for brooding, sea dragon males attach their eggs to their tail and carry them around until they hatch. Seahorses are listed as vulnerable by CITES and import (eg Chinese medicine) is banned by participating countries like Australia. Dragons have never been very common but are probably quite secure since our kelp forests are well protected in many places.
