Do You Know?
Jellyfish are soft and boneless creatures made mostly of water. They’ve existed for millions of years and are known for their unique and drifting movement.
No Skeleton Structure
Jellyfish lack bones and are composed of 95 percent water, which makes them buoyant. This unique structure allows them to float effortlessly.
Efficient Ocean Movement
Jellyfish move with little energy because of their soft, jelly-like bodies. They are well-adapted to the ocean's constant currents and tides.
Nervous System
Jellyfish have no brain but use a nerve net to sense surroundings and respond. This simple system guides them to food and away from harm.
Ancient Marine Lifeform
Jellyfish have existed for over 500 million years, making them one of the oldest marine creatures. They survived through major Earth changes.
Adapted to Aquatic Life
Without bones, jellyfish easily adapt to ocean temperature and pressure changes. This flexibility allows them to thrive in different ocean regions.
Hunting
Jellyfish catch prey with stinging tentacles, functioning well despite their soft, simple anatomy. They rely on stinging cells to immobilise prey.
