Algaeworms are large invertebrates native to Thanatos. Unlike most wildlife on Thanatos, these are omnivores, and half of their diet consists of the algae that clogs up the planet's oceans and rivers.
Algaeworms resemble sea cucumbers, but are much larger, at a length of up to 30 feet long and 1 ton. They are crimson red in color, with a black underside.
Algaeworms are omnivorous, feeding on algae, fungi and aquatic worms.
