THE REAL WORLD
The real Grass puffer
- Scientific name
- Takifugu niphobles
- Japanese name
- クサフグ
- Group
- Ocean animals
- Order
- Tetraodontiformes
- Family
- Tetraodontidae
- Genus
- Takifugu
A pufferfish often seen along the coasts of Japan; it is common in bays and often burrows into the sand.
It often enters places where seawater and river water mix, and very rarely even goes into fresh water.
On spring-tide nights from early summer into summer, many gather at the water's edge to spawn.
How the Grass puffer lives
Females lay eggs between pebbles, and males release sperm over them. During spawning, sperm clouds the water’s surface white. The newly hatched young swim offshore with the spring tide.
