Upside-down jellyfish breed at zoo
A smack of upside-down jellyfish has arrived at Bristol Zoo.
Experts say the jellyfish, which get their name from their upwards facing tentacles and mouth, have begun to breed at the centre.
The invertebrates eat small plankton but also have algae living inside their bodies to provide energy through photosynthesis.
Mark Bushell, assistant curator of invertebrates at Bristol Zoo, said: "We're really excited to welcome this unusual species to the zoo.
"They've settled in well and recently started breeding off-show where we hope to have many more baby jellyfish appear."
Upside-down jellyfish predominantly live in the Caribbean and depend on mangrove forests and shallow lagoons.
Coastal development and pollution mean these habitats are some of the world's most threatened ecosystems.
The 19 jellyfish at Bristol Zoo have arrived from ZSL London Zoo, Liverpool Aquarium and Bug House.
