Ecology of Pestarella tyrrhena

Main Ref.	Holthuis, L.B., 1991
Remarks	It is found from the mesolittoral zone to a depth of a few meters (there are records of depths to 70 m). It burrows in bottoms with well-sorted fine silicate sand with abundant interstitial foraminiferans and diatoms or sand and mud covered by dense meadow of Cymodocea nodosa (Ref. 86850). The burrows have several exits (Ref. 4) which are made up of plant debris and coarse sediment and may be as deep as 62 cm (Ref. 86850).
