These worms are found at the site of a "flish wreck", and are highly adapted for rapid growth inside the flish carcasses. They have three pairs of enormous jaws and are able to devour both the flesh and bones of the flish at a terrifying rate.
Grimworms reproduce by parthogenisis, which means that unfertilised eggs develop directly into identical larvae. Some develop into males, others are female.
When one of the females reaches the optimum weight of 10-15 gram she begins to devour her smaller siblings.
They have three pairs of enormous jaws to enable them to tear through the flesh and bones of the flish carcase.
After mating with a male from another flishwreck, she will then devour him, pupate and eventually emerge as a fully grown, pregnant Bumblebeetle.
