The lanceshark is a small aquatic omnivore/eater that is native to Mer (Reavers' Deep 2414). It is a highly palatable form of seafood that has caught on quickly.
The lanceshark is a migratory creature, whose schools can cover half the globe in the course of a lifetime. With a high reproductive rate, the harvesting of these schools by the raft communities has not significantly damaged the lancesharks. The main competition for the raft communities for these schools is the large, stupid, but dangerous gulperwhales.
