Yellow boxfish
Nsị n'akpụkpọ ahụ yaNri ya: Ntakịrị ihe niileNwere nsị n'ahụ, ọ naghị agba nsịThe yellow boxfish is a box-shaped fish with a hard, rigid body and bright yellow skin with black spots. It lives on coral reefs across the Indo-Pacific, from the Red Sea and east Africa to Hawaii and northern New Zealand. It is special because it can release a toxic mucus when stressed, which harms other fish nearby.1

Otú ị ga-esi mata ya
- Box-shaped body covered by a rigid, armoured shell called a carapace1
- Young fish are bright yellow with black spots all over the body1
- As it ages, the yellow fades and very old fish are blue-grey to black with faded yellow1

When stressed, it secretes a toxic mucus containing a neurotoxin called ostracitoxin, which attacks the nerves. This toxin is highly harmful to marine fish: it breaks down their red blood cells, which then clump together. Nearby fish may be killed when they are exposed to it.1

When threatened, it releases toxic mucus, and its bright yellow and black colours warn predators to stay away.1

Eziokwu
Engineers have studied boxfish to inspire designs for a concept car, bridge box girders and an airship.1
The carapace was once thought to help stability, but it was found to slightly increase drag and make the fish less stable.1
The fish can make humming and clicking sounds using the muscles of its swim bladder.1
The toxic mucus contains a bacterium, Vibrio parahaemolyticus, which may play a role in the fish's defence.1
Juvenile fish are brighter yellow than adults, and this bright colour is thought to deter predators early in life.1
Boxfish are strong, swift swimmers despite their stiff, box-shaped bodies.1
Onye na-ekpughe akụkọ ụgha
Akụkọ ụgha: Boxfish are weak swimmers because of their boxy shape.
Eziokwu: Boxfish are surprisingly strong swimmers. Their shape creates swirling water patterns that help them steer through reefs and make sharp turns.1
