They are common in nearly every freshwater habitat, where crem is found. Cremlings' appearance is not uniform. They are small and multilegged, bearing tiny claws and elongated bodies plated with carapace. Cremlings that display red claws indicate that they are poisonous.
The tiny creatures, which are commonly found in crem, are also known as "storm’s leavings." They scatter at the first sign of danger, retreating to their cracks and burrows. They are commonly used synchronously with "coward" as a derogatory term. Rotting wood and stagnant pools of water are good for growing cremling larvae.
