If you’re a little fish in an estuary full of birds, it’s best not to be caught out in the open. The mud-colored Arrow goby hides in the burrows of Ghost shrimps, Mud shrimps, and burrowing worms. It also uses these burrows as swimming holes during low tide. A goby does not make the best houseguest: it will eat its host’s young if it gets the chance.
This little fish will dive into another creature's burrow, such as a Ghost shrimp's, to escape predators.
What’s for Lunch:
Algae, protozoa, and the eggs of shrimps and other crustaceans
A borrowed burrow in the lagoon's sand and mud floor
