Phycologist humor - lorica evolution? Why have a lorica or shell? The lorica or shell likely evolved as protection against predation by other protists such as dinoflagellates and radiolarians who use feeding tubes and pseudopodia. The seemingly odd morphologies of planktonic organisms are the result of "Watery Arms Race" pitting prey against predator according to Victor Smetacek.
