Graceful – and gross!
Live Brittle Star
- Brittle stars are delicate starfish that live on the sea floor, often in great numbers.
- They have been around for over 500 million years, so they’re much older than the dinosaurs.
- Their five arms are ‘brittle’ – if one breaks off or gets eaten, they can grow another.
- Some brittle stars feed on dead animals. Others use their arms to filter the water for plankton.
- They don’t have an anus – they poo by spitting waste out of their mouths. Yuk!
- Brittle stars move rapidly by wriggling their arms to make snake-like or rowing movements.
- Some brittle stars can produce flashes of green or blue light to deter predators.
- See these beautiful brittle stars at Bridport Museum.
