The mantis shrimp “spearing” the
head of a fish. Mantis shrimp wait for fish to swim near their burrow
and then strike with their claws and drag them into their burrows. Their
strikes are so strong that they have been known to smash aquarium
glass.

Fish Using Jellyfish as Shelter

Jellyfish serve as a habitat to many ocean creatures…
Jellyfish play a critical role in the lives of different marine
creatures. While they are used as a direct food source for many, some
use them as shelter (juvenile fish), some as a means of travelling from A
to B and some have a combined interest of travelling while snacking on
the microscopic parasites attached to the Jellyfish.

These symbiotic relationships are very intricate and are being
investigated by scientists. [source]

In a never-before-seen phenomenon, a fish commandeered the body of a
jellyfish for protection. Although it is common for fish to swim through
jellyfish tentacles to avoid predators, this particular defense
mechanism has never been seen before.

“I
came across this fish (presumably a juvenile trevally) while snorkeling
along Double Reef on Guam in 2013. The fish swam in and out of the
crown of the jellyfish multiple times over the course of several
minutes. The fish was able to steer the jellyfish as it swam inside,
often turning away from me as I followed. It has been postulated that
the fish is using the jellyfish as a shield to protect itself as it
swims in open waters.”
