The Bulbocula Class makes up the bulk of large animals on Odin’s surface. The jointed, articulate mouthparts possessed by their ancestors have evolved into limbs whose primary purpose is locomotion. In addition, they have adapted the flexible olfactory antennae/tendrils present in most Odifauna into muscular paraglossae designed to move food toward their mouths. Bulboculae are extremely diverse and inhabit a range of environments.
The life cycle of the Parallos Order is made up of five stages: egg, nymph, mobile adult, pupa, and sessile adult. The rubbery, translucent eggs are laid in water, and eventually hatch into a nymph that spends the majority of its life in water. When it’s gradual change into the mobile adult form is complete, it is able to crawl out onto land and breathe air, though it stays close to the water. Parallos species keep their reproductive display appendages year-round, but the color gets more intense during the mating season. Once they have mated, they metamorphose into a pupa and in a matter of weeks emerge in their sessile adult form. At this stage of their life, they feed by sifting particles out of the seafloor or coast, and spend their time growing eggs which are then flung out into the water.
