“Though the Kinabalu Giant Red Leech is called a leech, it doesn’t feed on blood”

The Kinabalu giant red leech definitely lives up to its name. This insect is bright reddish-orange in color and is twenty or more inches long. It’s found on a mountain in Borneo. Kinabalu giant red leeches are carnivores eating a worm that lives alongside it in Borneo.

Kinabalu Giant Red Leech Species, Types, and Scientific Name

Mimobdella buettikoferi is the scientific name of the Kinabalu giant red leech. While the word Mimobdella is the genus of the insect, the word buettikoferi is a reference to Johann Buttikofer. Johann Buttikofer was a naturalist who collected one of these insects for study.

Kinabalu giant red leeches belong to the Salifidae family. Leeches are identified by their slow, inchworm-like movements. The Mimobdella is a genus within the Salifidae family. The three leeches in this genus include:

  • Kinabalu giant red leech-Mimobdella buettikoferi
  • Mimobdella japonica
  • Mimobdella africana

Appearance: How to Identify a Kinabalu Giant Red Leech

The size of this insect is its most notable feature. It can grow to a length of 20 inches or longer. It has slimy bright reddish-orange skin. The narrow body of this insect allows it to fit into the crevices of rocks in its mountainous habitat. It slowly propels its segmented body across the wet soil in search of its prey. Four to six years is believed to be the lifespan of this leech.

When you think of the word leech, you may picture a slimy creature with a thicker, shorter body designed to latch onto its prey. The Hungarian leech is one example. It has a thick body with skin featuring a colorful pattern of green, red, and black. The Hungarian leech feeds on blood. The Kinabalu giant red leech looks more like a worm than a typical leech.

It’s tempting to compare the Kinabalu giant red leech to a nightcrawler you may see on the sidewalk. They are both slimy, segmented insects. But the biggest nightcrawler only grows to be a little over nine inches long. Plus, brown nightcrawlers can easily blend into their soil habitat.

Another difference between nightcrawlers and Kinabalu giant red leeches is nightcrawlers are not carnivores. Instead, they eat decomposing plants and vegetables. They may even be found in a backyard compost pile.

Kinabalu giant red leeches are vulnerable to predators because of their bright color. So, their only method of self-protection is to slide into rock crevices in order to stay hidden.

These leeches are solitary. They stay in rock crevices most of the time. In fact, they are only seen during heavy rainfall or just after a storm. This is when their Kinabalu giant earthworms are washed up out of their hiding places.
