THE REAL WORLD
The real Yellowfin goby
- Scientific name
- Acanthogobius flavimanus
- Japanese name
- マハゼ
- Group
- Ocean animals
- Order
- Gobiiformes
- Family
- Gobiidae
- Genus
- Acanthogobius
Its pelvic fins form a sucker-like disc, so it can stick to rocks and other surfaces.
With a mouth that is big for its body, it eats small crustaceans such as shrimp and crabs, as well as ragworms, on the seafloor.
How the Yellowfin goby lives
From autumn into winter, it moves to slightly deeper water. The male digs a burrow in the seabed. The female lays her eggs inside that burrow.
