Heterophrys marina Hertwig & Lesser (1874: 140)

Description

Cells spherical, densely covered with pseudopodia and organic spicules protruding through a gelatinous (spicule?) coating. Cell body (6–) 10–25 (–83) µm diameter. Pseudopodia 10–30 µm long. Spicules needle-like, 1–13 µm long, mostly arranged radially, the remainder forming a mat over the cell surface.

Distribution

Southern Ocean, south of Australia; Norway (Tobiesen, 1991).

Comments

Under LM, the spicules sometimes appear as an ill-defined halo around the cell. Heterophrys is distinguished from other heliozoea, e.g. Acanthocystis, by the absence of silicious body scales.
