In this article of the Animal Expert on the world’s largest Jellyfish we show you all the details about this giant inhabitant of our seas.
Its common name, jellyfish-leek comes from its physical appearance and the resemblance to the mane of a lion. Within this jellyfish, we can find other animals like shrimp and small fish that are immune to their poison and find in it a good food finte and protection against other predators.
The jellyfish-leeward has eight clusters where its tentacles are grouped. It is estimated that its tentacles can reach up to 60 meters in length and these have a color pattern ranging from crimson or purple to yellow.
This jellyfish feeds on zooplankton, small fish and even other species of jellyfish trapped between its tentacles, to which it injects its paralyzing venom through its stinging cells. This paralyzing effect facilitates the ingestion of their prey.
Habitat of the world’s largest water-life
The jellyfish live mainly in the cold and deep waters of the Antarctic Ocean, extending also to the North Atlantic and the North Sea.
There are few sightings that have been made to this jellyfish, because it inhabits the zone known as abyssal that is between 2000 and 6000 meters of depth, being very infrequently its approach to the coastal zones.
Behavior and reproduction
Like the rest of the jellyfish, its ability to move depends directly on ocean currents, limiting itself to vertical displacement and much less to the horizontal. Due to these limitations of movement it is impossible to carry out persecutions, with their tentacles being the only weapon to feed themselves.
In most cases, jellyfish bites are not fatal in people although they may suffer from severe pain and rashes . In very extreme cases, if a person gets stuck in their tentacles, this can be deadly due to the large amount of venom absorbed by the skin.
The jellyfish-damsel reproduces in the summer and fall. Although they mate, they are known to be asexual, producing both ovules and sperm without the need for a mate. The mortality rate of this species is very high in the first days of life of the individuals.
