Leafy Seadragon

Found singly, or in pairs, anchored with their tails, in kelp beds, and over sand patches, close to reefs, also, sometimes off-shore, attached to drifting seaweed rafts.
They feed on crustaceans which they suck whole into their mouths.
Eastern Indian Ocean - Southern Australia

Pipefishes and Seahorses are unique in that the male gives birth! The female deposits their eggs after fertilisation into the males pouch to incubate the eggs for one month before giving birth.
They attach to anything they can get their tail around, even each other usually close to the bottom to blend in with their surroundings.
Seahorses are a threatened species because it is sought after for Chinese medicine.
