Gymnosphaerid |
 | | The gymnosphaerids are a group of heliozoan protists, found in marine environments, and including both mobile and sessile forms. |
| | Gymnosphaerids tend to be roughly spherical, with radially directed axopods arising from an amorphous central granule. |
| | These are cell projections supported by hexagonally arranged microtubules, as in the centrohelids, from which the gymnosphaerids are distinguished by having tubular rather than flat cristae in the mitochondria. |
