The longhorn cowfish is a small, boxy reef fish with two long horns above its eyes, like a cow's. It lives in warm waters across the Indo-Pacific, from the Red Sea to Japan and Australia. It is a slow swimmer that protects itself with a hard box-like body and a skin poison.1

Giftig deur 'n byt of steek, of giftig om aan te raak of te eet? Sommige diere spuit gif in met 'n byt of 'n steek. Ander is skadelik om aan te raak of te eet. Hierdie een is giftig om aan te raak of te eet.

Tuis

It mainly lives on coral reefs in lagoons, reef flats, estuaries, bays and protected seaward reefs, usually over sand or rubble bottoms. Adults are often solitary and territorial. It is found at depths of 1 to 45 m, and perhaps up to 100 m.1

6,5 cm tot 50 cm (2,6 in tot 1,6 ft)1

Gewig

12 g tot 156 g (0,4 oz tot 6 oz)1

omtrent 4 km/h (2,5 mph)

Swem, rowwe skatting

Wat eet dit?

It eats benthic algae, microorganisms and foraminiferans, which it strains from sediment. It also eats sponges, polychaete worms, molluscs and small crustaceans and fish. It feeds on animals living in sand by blowing jets of water into the sandy bottom.1

Hoe om dit te herken

Two long horns stick out from the front of the head, above the large eyes1
Its body is a solid, triangular, box-like shell made of fused plate-like scales, with the fins and tail sticking out1
The base colour is yellow to olive, decorated with white or bluish spots1
It has no gill cover, only a small slit or hole behind the head1
It swims slowly with its fins, so it looks as if it is hovering1

Gifkrag

Gif in sy vel

Sy vel is giftig. Dit is gevaarlik om aan te raak, te lek of te eet.

Wat doen sy gif as jy daaraan raak of dit eet?

When it is severely stressed, it can release a toxin called pahutoxin from the mucus on its skin. This poison is toxic to other boxfish and has properties similar to sea cucumber toxins.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: LigSoos 'n bysteek of minder. Basies onskadelik vir mense.

Wat doen dit as dit bang is?

Its hard box-like shell, its horns, which can be used to charge at predators, and its skin poison all protect it. If severely stressed, it may release its toxin.1

As iemand daaraan geraak of dit geëet het

As iemand dit geëet het of simptome kry nadat hy dit geëet het: bel dadelik jou noodnommer of 'n gifsentrum.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As jy daaraan geraak of dit geëet het: moenie jou oë of mond vryf nie, was jou hande en kry mediese hulp.

Dit is nie uit om jou te kry nie. Sy gif is net daar sodat niks dit eet nie. Meer oor veilig bly

die moeite werd om te weet

Feite

Its horns may have evolved to make it harder for predators to swallow it, and if damaged, they can grow back within a few months.1

It can make humming and clicking sounds using muscles connected to its swim bladder.1

It is slow and easy to catch by hand, and it makes a grunting noise when caught.1

On Pamban Island in India, a local belief says cows on the island turned into these fish when the land separated.1

It helps protect coral reefs by eating invertebrates that damage them, and it is also important to reef growth.1
