Ancestor:Descendants:

The jet worm split from its ancestor. In the populated Somarinoa Coast, it was easily caught by predators so it evolved a way to escape; its fins have grown smaller (as predators usually went for these to catch it) and at the base of each fin, pores have opened up. The worm sucks sea water into these pores, which are connected to channels that lead to the segments of its abdomen. The channels are impermeable to water, preventing water loss to the salty sea water. The worm controls when and where the sea water is released from these pores, using them only when it needs to escape from a predator quickly. The result is the water is used as a jet to propel the worm away from harm.


It attaches its eggs to the purple sea bubbleweed; these eggs are colored purple for camouflage. Its tail has changed slightly because it doesn't use it as much for movement through the water. Its eyes have grown flat to help its streamlined shape.
