dactylethra

One of several hollow fingerlike projections found on some bryozoans, used to absorb nutrients.

Erkosonea differs from that genus in the presence of dactylethrae instead of tergospores.

The dorsal is hardly convex; it is formed by a thick layer of dactylethrae closed by a thin calcareous lamella. The dactylethrae appear on the frontal at the birfurcations.

Instruments used in Stomatology: Bouglosson (tongue scraper or depressor), dactylethra (finger stall), lithanaboleus (parotid duct stone hauler), stomatodiastoleus (mouth opening instrument), sphenarion (wedge to keep mouth open),

The egg gauze was carefully collected from the field after 48 h of exposure and maintained within 10 ml glass dactylethrae.
