Yellow boxfish
The 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

Mmene ungaizindikirire
- 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
- Usually found alone, as it is a solitary fish1
Nthawi zambiri imasokonezedwa ndi: The spotted boxfish (Ostracion meleagris) has the same box shape and spots. The yellow boxfish is mainly bright yellow with dark spots, while the spotted boxfish is darker with white spots.1
Mphamvu ya poizoni
Khungu lake lili ndi poizoni. Ndi yoopsa kuikhudza, kuinyambita kapena kuidya.
Poizoni wake umachita chiyani?
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
Ngati munthu waikhudza kapena waidya
- Ngati munthu waidya kapena ali ndi zizindikiro ataidya: imbira nambala yadzidzidzi kapena malo othandiza pa za poizoni (poison centre) nthawi yomweyo.

Khala wotetezeka
- Usakhudze, kugwira kapena kuseweretsa nyama yakuthengo, ngakhale yaing'ono, ndipo ngakhale ikuoneka ngati yagona kapena yafa.
- Ipatse malo. Ukakumana nayo, khala chete, bwerera m'mbuyo pang'onopang'ono ndipo uilole ipite njira yake.
- Ngati unaikhudza kapena kuidya: usasisite maso kapena pakamwa, sambitsa m'manja ndipo peza thandizo la dokotala.

Mfundo
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
Kuthetsa nthano zabodza
Nthano yabodza: Boxfish are weak swimmers because of their boxy shape.
Zoona: Boxfish are surprisingly strong swimmers. Their shape creates swirling water patterns that help them steer through reefs and make sharp turns.1
