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.

It has a white, transparent mantle, often with small,

irregularly distributed red dots.

However, these dots can also be completely absent,

so that the mantle is uniformly white.

The edge of the mantle is surrounded by a two-coloured band,

red on the outside and yellow on the inside.

Gills and rhinophores are transparent red

Photo 1 Johnny: Lembeh Strait North - Sulawesi

 Maximum length: 50 mm

The tubercles have orange to red tips with white edges.

The gills and rhinophores have small dark brown spots.

This snail has variable body colours, which can be orange, yellow,

yellow-brownish, reddish or dark brown.

Its uniform, radial pattern always ends in a point.

These strongly pronounced tips distinguish them from other Halgerda species.

Photos 1 - 2 Johnny: Bangka Island North Sulawesi

 Maximum length: 15 mm

This snail has a reddish-brown, dark grey to sometimes,

almost completely black body colour with small white dots.

Its rhinophores are always the same colour as its body, except for the tips,

which are always white.

Although they are said to grow up to 15 mm in size,

almost all specimens found are smaller than 1 cm, even this one was smaller.

Maximum length: 600 mm

Many divers know this beauty.

Its ability to swim with graceful undulations of its mantle edge has earned it its name.

They are usually only seen at night,

but this year I was lucky enough to see one dancing near the surface during the day.

A picture you won't forget in a hurry.

Photos 1 - 2 show the clutch of the Spanish dancer.
