Hydrozoan

Agalma okenii

• Group: Other
• Typical depth: 0–1000 m

A drifting colony rather than a single animal, this siphonophore strings together specialised bodies into a chain that hunts as one through the open water. It hangs in the dark midwater from the surface down to around a thousand metres, trailing stinging tentacles to snare passing prey.
