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

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

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

Eziokwu

1

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

2

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

3

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

4

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

5

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