Hydroid

Clytia hemisphaerica

• Group: Other
• Typical depth: 0–1135 m

A colonial hydroid that grows as a low creeping turf, it settles on mangrove roots, ledges and floating weed from the surface to over a thousand metres. It releases tiny medusae that drift off to spawn, a stage scientists study closely in the lab.
