The crucifix goby is a small marine fish up to 15 centimeters long. Males have a noticeable fleshy crest on their head, which is why the fish got its name.
The crucifix goby differs from other gobies with a well-noticeable fleshy crest in males and a sucker from the pelvic fins. It helps keep the sea floor clean by eating small animals and serves as food for larger fish.
Immature form that undergoes metamorphosis before adulthood.
