Propuldiomysis

The Propuldiomysis is a descendant of Diomysa. Its tentacles fused into just two, horizontal tentacles. It is omnivorous and will eat whatever it can get its tentacles around. It swims by moving the fins on either side of it in opposite directions. It mates the same way as Diomysa did, although the larva will stay suspended in water until they develop fins. Their tentacles still have chemoreceptors but they rely more on their front facing eyes to find food. A large Propuldiomysis is pictured here about to feed on a bosseo magno plant.

Basic Information

Anatomy

While it may seem like Propuldiomysis is closely related to the species of Protomisanidae, this is in fact a convergent condition, and they are not very closely related. In this line the fins have paired off into two sets of two pairs, each set of pairs operates as a linked group and they are offset, with the anterior pair of the set being slightly raised towards the dorsal side, while the posterior pair in the set is lowered towards the ventral, this maximizes the amount of water that can be moved on the back stroke. The face appendages of the basal Dyomisa are merged into a single pair of feeding appendages. The interplay of muscles and ligaments within the joined appendages has created the beginnings of a hinge like joint about half way down the appendage. This increases the strength of the feeding appendages at the cost of flexibility.

Ecology and Habitats

As a generalist Propuldiomysis thrives in a wide range of environments in the waters between Natash and Ras al-Kalb, as well as the shallower regions south of Natash.
