Sapocribrum chincoteaguense, microscales – From Lahr et al, 2014

Genus Sapocribrum  Lahr et al, 2014

Diagnosis: Amoebae bounded by a continuous thin, somewhat flexible, envelope separated from the plasma membrane and having oval scalelike substructure within a denser matrix; small pores penetrate the envelope, allowing subpseudopodia to protrude for very slow, occasional locomotion; locomotive cells flattened, oval, rounded or irregularly triangular.

Type species: Sapocribrum chincoteaguense n. sp. (Monotypy)

Sapocribrum chincoteaguense, filopodia – From Lahr et al, 2014

Sapocribrum chincoteaguense Lahr et al, 2014

Diagnosis: Amoeba with characters of the genus, less than 5 µm (more usually 3-4 µm), with typical locomotive angular form that moves infrequently, and when sedentary emits only one to a few long filose pseudopods at a time. Pseudopods may bifurcate. Pseudopods 4.42  0.28 µm, varying from 2.5 to 9 µm. During brief periods of locomotion, the body remains contracted and angular in shape moving in a meandering path in the direction of the extended adhesive pseudopodia, that appear to adhere to the substratum and pull the amoeba forward. Surface contains microscales (~150 X 100 nm in mean length and width, respectively).

Ecology: bottom sediments, marine
