Migration might be too strong of a term, but box jellies do demonstrate seasonal movement. During the spawning season (May - July) in Australia, box jellies congregate in the lower portions of freshwater rivers and mangrove channels. Their offspring then travel out to the coastal beaches during the wet season (Oct - Apr), where they grow to adult size and pose a serious threat to humans. Their life cycle completes when they travel back to the estuaries to sexually reproduce and then die.
There are dozens of box jelly species with varying life cycles and scientists are still largely unaware of the exact details, but the above description is generally true for the majority. Hibernation is not known to exist in these species.
The box jellyfish is motile (capable of motion). In fact, it can move more rapidly than other jellyfish thanks to its velarium that concentrates and increases water flow. It also has a more developed nervous system than most other jellyfish. In Australia, Hawaii, and Japan, among other areas, there are several species of extremely venomous jellyfish; people can die within a very short amount of time without treatment.

Are animalia motile or non motile?
they are sessile
How does the baby jellyfish change as it grows into an adult?
It starts as a sessile polyp like creature and then buds to form motile medusoid adults.
Is a jellyfish a sessile?
No, a jellyfish is not sessile. Jellyfish are free-swimming marine animals that use pulsations to move through the water. They are part of the phylum Cnidaria and have a simple body structure with tentacles for capturing prey.
Are ferns motile or non motile?
most people believe that plantae are motile
What is the opposite of a sessile?
The opposite of sessile is motile. Motile organisms are able to move or change position on their own, as opposed to sessile organisms which are fixed in one place.
Are plants motile or sessile?
dont no
What are fungi motile or non-motile?
Fungi are non-motile organisms, meaning they cannot move on their own. They rely on external factors like wind, water, or animals to disperse their spores for reproduction.
What is a sessile form of a jellyfish called?
POLYP
Is a amoeba motile or sessile?
Amoebas are motile, meaning they are able to move and change shape by extending and retracting pseudopods, which are temporary projections of cytoplasm. This allows them to move toward sources of food or away from unfavorable conditions.
Are most producers motile or sessile?
Most producers are sessile, meaning they are stationary and do not move from one place to another. This includes plants, algae, and some types of bacteria. These organisms generally rely on other means, such as wind, water, or animals, to disperse their spores or seeds for reproduction.
Sea anemone and sponge are sessile why are they group into animal?
Their larvae stages are motile stages.
Motile and sessile?
"Motile" refers to organisms that are capable of movement, such as animals and some single-celled organisms. "Sessile" refers to organisms that are fixed in one place and do not move, such as plants and some types of animals like sponges.
