The real Splendid alfonsino
- Scientific name
- Beryx splendens
- Japanese name
- キンメダイ
- Group
- Ocean animals
- Order

- Family
- Berycidae
- Genus
- Beryx
A deep-sea fish that lives around rugged, rocky areas in deep water. As it grows, it moves farther offshore into deeper water.
Its golden eyes, which give the fish its Japanese name, have a mirror-like layer that reflects light, helping it make the most of dim light.
Its body is bright red. Red is very hard to see in the deep sea, so this color helps it stay safe from enemies.
How the Splendid alfonsino lives
Young fish live near the coast. They eat lanternfish, shrimp, squid and other animals.
