THE REAL WORLD
The real Clark's anemonefish
- Scientific name
- Amphiprion clarkii
- Japanese name
- クマノミ
- Group
- Ocean animals
- Order
- Blenniiformes
- Family
- Pomacentridae
- Genus
- Amphiprion
A fish that lives in partnership with sea anemones, each helping the other. It rests among the anemone's tentacles and lays its eggs right beside it.
Sea anemone tentacles carry venom, but this fish covers its body with a special slime, so the venom does not harm it.
It is neither male nor female when it hatches. As it grows it becomes male, and later it changes into a female.
How the Clark's anemonefish lives
It is active during the day. It mainly eats zooplankton and algae. The male does most of the egg care. After hatching, the young drift in the sea before finding an anemone to live in.
