Jellyfish

About

How jellyfish lives

Jellyfish drift through the water column using pulsing bells and stinging cells to catch tiny prey. Jellyfish have no bones, brain, or heart, yet some species can form huge blooms. Ocean animals navigate three-dimensional space, pressure, and constantly shifting currents.

Conservation

Status and habitat pressure

Stable populations still depend on habitat quality, food availability, and low human pressure. Protecting jellyfish also depends on keeping ocean, coast habitats healthy and connected.

Common species still depend on habitat quality, clean water, food webs, and low disturbance.
