Observations on the burrows and burrowing behaviour of Brachynotus gemmellari and on the burrows of several other species occurring on Squilla grounds off Ancona, Central Adriatic

Abstract

The paper presents information on the burrows of a number of species that occur on Squilla grounds in the coastal Adriatic off Ancona, Italy. The burrows and burrowing behaviour of Brachynotus gemmellari are described for the first time. For Upogebia tipica, Solecurtus strigilatus and Gobius niger, the observations add to sparse burrow information in the literature. Little is known of the burrows of Echiura in the Mediterranean: those of two species are briefly described from surface features.
