Jolly Jellyfish
From the Series At the Aquarium
The sea is full of jolly jellyfish! Tiny, boxed sea wasps have box-shaped bells and pack a powerful sting. Adult immortal jellyfish can turn back into a baby when they are in danger. And the bell of the compass jellyfish looks like (you guessed it!) a compass! Learn about these and more jolly jellyfish at the aquarium.
