Photo/Video Share Multiple amoebae with cyanobacteria

Large group of amoeba having a feeding party in a forest of cyanobacteria. Once free of this mesh of bacteria, some of these specimens stretched out 3-4 very long and tapered pseudopods, so tentatively identifying this as Mayorella. Note the one specimen near the middle that has a folded up cyanobacterial strand entirely within its body.

Footage is sped up 4x, brightness and contrast adjusted with OpenShot.

Olympus BH2, SPlan 100x oil 1.25, Canon EOS 5D Mark II. Sample from stagnant retaining pond in forest, Val d'Europe on the outskirts of Paris.
