Biology:Hyolithida
From HandWiki
The Hyolithida are lophotrochozoans, one of the two orders of hyoliths, the other being the Orthothecida. Most of our knowledge of the hyolithids comes from studies on the Hyolitha.[1] Both orders had an operculum that was not hinged to the conch. However, the Hyolithida are distinct from the Orthothecida in having additional paired, curved, tusk-like appendages. The Hyolithida were probably bottom feeders living in shallow water, and had tentacules.[1]
