Leptomyxa sp.

Diagnose: Slowly moving amoeba with a long tubular body with some lobopodia at both ends extending in several directions and also with subpseudopodia. During locomotion, it is one long monopodium, up to 3 mm! The cell is covered with a layer of small xenosomes collected from the environment. Nuclei numerous, small, spherical, 2.5-3.0 µm. The specimen was not sensitive to light.

Ecology: In the Gooimeer, a large freshwater lake in the Netherlands, between basalt rocks.

Remarks: I found this very large amoeba in 2021. I could observe it for some days in a wet mount. I have found only one specimen.
