Diving In Singapore: The Pyjama Nudibranch

Found right in our local waters at Pulau Hantu so you don't have to travel to Bali etc to see our friend!

  • Mexichromis mariei is a species of colourful sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Chromodorididae.

  • It is sometimes called the pyjama nudibranch.

  • They reach a maximum size of 60 mm (2.4 in) in length. Found in the intertidal zone up to 30m.

  • It has a tendency to form reddish purple-tipped rounded papillae on its back. The background colour ranges from translucent white or purple to a deep cream yellow. The mantle border usually consists of a row of orange or yellow spots, but can sometimes be a continuous band.

  • Mating behavior: Both individuals darts their penis toward each other to induce one to act as a male and the other as the female. The victorious one to penetrate the body wall is the dominant male.
