Jelly Nanny

Songda Cai's Image

A trevally stared out from inside a jellyfish. Far from being trapped, the young fish was exactly where it wanted to be: swimming under a jellyfish’s bell to seek refuge from predators deterred by its host’s sting. Songda spotted this couple while night diving and captured their vibrant colours against the darkness.

At least 80 species of fish turn to jellyfish for protection; the jellyfish do not usually suffer or benefit from this practice. However, if seawater grows more acidic, as is predicted with climate change, it could affect the senses of the fish, causing them to become less attracted to their hosts. They may then spend more time in the open, exposed to predators.
