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

Nola ezagutu
- 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
Askotan honekin nahasten da: 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
Pozoi-indarra
Bere azala toxikoa da. Arriskutsua da ukitzea, miazkatzea edo jatea.
Zer egiten du bere toxinak?
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
Norbaitek ukitu edo jan badu
- Norbaitek jan badu edo jan ondoren sintomak baditu: deitu berehala zure larrialdi-zenbakira edo intoxikazio-zentrora.
Deitu beti lehenik zure larrialdi-zenbakira (112, 000, 911). Lehen sorospenei buruzko orientabide orokorra da hau, ez mediku-aholkua. Lehen sorospenen oinarriak
Egon seguru
- Ez ukitu, ez harrapatu eta ez zirikatu inoiz animalia basati bat, txikia izan arren, eta lo edo hilda dagoela badirudi ere.
- Utzi tartea. Bat aurkitzen baduzu, egon lasai, egin atzera poliki eta utzi bere bidetik joaten.
- Ukitu edo jan baduzu: ez igurtzi begiak edo ahoa, garbitu eskuak eta lortu mediku-laguntza.
Ez dabil zure atzetik. Pozoia ezerk jan ez dezan baino ez du. Seguru egoteari buruz gehiago

Datuak
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
Mito-hauslea
Mitoa: Boxfish are weak swimmers because of their boxy shape.
Egia: Boxfish are surprisingly strong swimmers. Their shape creates swirling water patterns that help them steer through reefs and make sharp turns.1
