Herodotus describes certain dwellings of this kind on Lake Prasias in Thrace as being approached by a narrow bridge, each habitation having a trap-door in the floor, giving access to the water beneath, through which fish were caught. The remains of a great number of such dwellings, some of them o to prehistoric times, have been met w on Europe, among the first having been discovered in 1839 in the small lake of Lagore, in the county of Meath, Ireland, in which country they are styled crannogs or crannoges.

The animals are protected by a lateral bivalve shell, the two valves of which articulate over the back, and are opened by an elastic ligament and closed by one or two adductor muscles. The shell is secreted by a prolongation of the integument called the mantle or pallium, which laps round the body, its halves being either free or united so as to leave only three apertures for the inlet and outlet of water for respiration, and for the protrusion of a fleshy organ called the foot, when it is present.

Respiration is effected by two pairs of lanellated gills (whence the name), occupying a large portion of the interior of the shell on each side. The mouth is a simple jawless fissure, furnished with one or two pairs of soft palpi, the food being conveyed to it by cilia on the gills.
