This species of snail can be found at a depth of 2 - 10 metres.

The brown, beige and yellow spots look like fried eggs,

which is why they are also called Hoplodis fried eggs.

Different colour variants

This snail species has a particularly prominent horn,

which is said to contain a particularly large amount of the tasteless sponge venom.

This horn is intended to entice potential predators to bite

into it when attacked in order to protect the actual body.

The poison in the horn tempts attackers not to attack again.

The body of the snail appears long and narrow and can have different colours.

As the name suggests, this nudibranch is black.

Depending on age, it has different color variations, so very young animals are often pink or orange,

adult animals are black with or without white spots.

In the “intermediate stage” they have a more or less broad orange-red band around the mantle.

They can be found under stones, rocks, gravel, sand, coral rubble and in algae meadows.
