Nudibranch Basics

Scientific Names Explained

Common names are fun, but scientific names are the clearest way to identify nudibranchs accurately.

Common names vary between dive guides, countries and websites. Scientific names give divers and photographers a shared language.

How a scientific name works

Chromodoris willani
Genus

Chromodoris

The broader group. Think of it as the family name.

Species

willani

The individual species within that group.

Common names can overlap

Names such as polka dot, black and white or pyjama can describe more than one animal.

Scientific names travel well

A scientific name can be understood by divers, photographers and researchers around the world.

Photos still matter

Correct identification also depends on body shape, colour pattern, rhinophores, gills and location.
