The Caspian star goby-tadpole is a small bottom-dwelling fish that lives only in the Caspian Sea. It has a large head, short body, and skin with sharp star-shaped tubercles.
The Caspian star goby-tadpole differs from other gobies with its star-shaped tubercles and very large head. It helps maintain balance on the sea bottom by eating small invertebrates and serving as food for predatory fish.
Immature form that undergoes metamorphosis before adulthood.
