The Sandswimmer is another dual-habitat animal in the course of its life cycle.

From birth through the first year of life, the baby Sandswimmer is exclusively aquatic. They are akin to the piranha from our archives, travel in schools, and attack prey far larger than any one of them could individually. The concurrent oxygen transport mechanism below their skin does not develop until the second year, accompanied by the hardening upper “shell” of this water borne terror. The Sandswimmer can only leave the water for prolonged periods of time, estimated in weeks, when these development milestones have been taken place.
