The Flower Hat Jellyfish is a highly colorful species of jellyfish principally native to a small area in the Western Pacific Ocean, just off the coast of Japan, in Asia. Only random individuals have been found in other locations and that may be due to accidental relocation by human activity.
The species remains popular for its flamboyantly colored tentacles which it keeps coiled near its body when not in use.
The Flower Hat Jellyfish rarely interacts with humans. Generally, this interaction only occurs when the individuals have grouped together in large numbers. Science calls these groupings blooms.
Flower Hat Jellyfish Habitat and Physical Description
The Flower Hat Jellyfish is endemic to only one restricted area of ocean. Yet random sightings of individuals have also occurred near Argentina and Brazil.
They prefer to dwell near the ocean floor. There, they typically will remain near seagrass and kelp growths.
The species attains a maximum diameter of around 6 in (15 cm). Their lifespan ranges from 4-6 months. The sting of an individual is painful, but not harmful to humans. Only in their blooms are they dangerous to humans.
Flower Hat Jellyfish Diet and Behavior
The Flower Hat Jellyfish primarily feeds upon a variety of species of small fish. They will also occasionally consume small marine invertebrates which they typically scoop from the ocean floor. Their tentacles serve a dual function for feeding.
The jellyfish’s venom is highly potent against the small prey they prefer. After stinging the prey, the tentacles then grasp the prey firmly.
It possesses a uniquely useful adaptation. When food is scarce, their bodies will actually shrink to require less sustenance. When the abundance of prey increases, their body size will also increase.
