5 Interesting Facts About Red Triangle Slugs

Red Triangle Slug, Triboniophorus graeffii

This is a red triangle slug crawling along the ground

Today I want to write about a very strange looking slug called the red triangle slug.

Here are five interesting facts about them:

  1. These large slugs grow up to 15 cm long, making them Australia’s largest native slug.
  2. They come in a range of colours, including white, yellow, grey, beige, pink, red, orange or green, and every colour combination has the red triangle on its back that gives them their name.
  3. The red triangle has a hole that they use to breathe from.
  4. They hide under bark during the day and come out at night to eat the lichen off trees and rocks, leaving a very distinctive trail of small circle behind.  They sometimes even come inside houses to eat the mould from bathrooms.
  5. Red triangle slugs are found in forests and backyards along the east coast of Australia.

I hope that you found these facts interesting and learned something new.

Are there any other interesting facts that you would like to share about red triangle slugs?
