Hoopfish

Small, school-mentality prey fish with a unique method of propulsion, and a distant relative of the bladderfish.

1. Antennae

Rather than swimming, this lifeform uses the fine green antennae which encircle its body to alter the composition of the water in front of it, allowing it to 'sail' into the low density space created.

2. Purple/Green Coloration

May be a camouflage adaptation for mid-range light wavelengths, possibly indicating the hoopfish is more active at dawn and dusk.

3. Behavior

While schools of hoopfish will form periodically and evade predators en masse, this behavior is more social than it is defensive, and lone hoopfish are often found hunting for food and displaying generally curious behavior. Assessment: Edible
