Many jellyfish have symbiotic species, from fish to crabs to shrimp, that live on, in, or around the jellyfish.
Jellyfish can provide shelter for young fish or crustaceans, protecting the fish from predators within their bell or among their stinging tentacles until the fish are big enough to fend for themselves.
The beautiful honey-gold, amber or moss green colours of a Papuan spotted jellyfish are produced by its symbiotic algae.
