Vampyrella spec.

 

This Vampyrella species attacks Mougeotia cells. It makes a large hole in the algal cell wall. The protoplast of the algae moves very fast into the Vampyrella cell. One specimen can feed on several algal cells before digesting it in a digestive cyst. The time between touching an algal cell and sucking up its protoplast can be within two minutes!
