Olinda Formosa

 – Flower hat jelly – 

 

Description:

Olindas formosa is a species of jellyfish characterized by lustrous tentacles, which coil and adhere to the rim when not in use. The flower hat jelly’s bell is translucent and striped with opaque bands, making it easily recognizable. This species can grow to about 15 cm in diameter. It lives circa 4–6 months.

Behaviour:

The venom of the flower hat jelly is highly potent against the small prey it prefers. After stinging the prey, the tentacles grasp it firmly. Olindas formosa possesses a uniquely useful adaptation. When food is scarce, its body will shrink to require less sustenance. When the abundance of prey increases, the body size will do the same.

Habitat:

Coastal waters, semi-benthic (spends time near the seafloor). Typically prefers kelp and seagrass beds.

Distribution:

Southern Japan, Argentina, Brazil and the Mediterranean.

Food:

Small fish and occasionally invertebrates.
