Shovelheads

Shovelheads are the basal group from which modern swarmers and shockers both evolved.

Evolution
Plents began from a photosynthetic unicelluar organism that bore two flagella. The organism then evolved many more cells, and became an organism that sifts the water for smaller organisms while photosynthesizing at the same time. Shovelheads never left the oceans. Shovelheads lead to the swarmer lineage.
