AboutWith brown marking reminiscent of a compass, this jellyfish is really quite distinctive. A summer visitor to our shores, the compass jellyfish feeds on small fish, crabs and even other jellyfish. They give a nasty sting, so if you spot them during a visit to the beach – look, but don’t touch! Once they have stung something, jellyfish often leave the tentacle behind and can continue to sting using it even when not to connected to their body.
How to identifyA translucent yellowish-white jellyfish with brown markings around the fringe and on the top of the bell. Those atop the bell resemble a compass, with V shapes radiating out from a central point. They have a bunch of frilled oral arms below the bell and long thin marginal tentacles around the fringe of the bell.
Don't get too close to those tentacles though, they give a nasty sting.
