Ecrobia truncata, common name the truncated marsh hydrobia or minute hydrobia, is a species of very small aquatic snail, an operculate gastropod mollusk in the family Hydrobiidae.[1]
Distribution
This species can be found along the coasts of Virginia, Massachusetts and Canada , the Northwest Atlantic Ocean and along the coasts of the British Isles and Scandinavia and in the Mediterranean Sea.
Description
The maximum recorded shell length is 5.8 mm.[2] The small shell is elongate to ovate. Its color varies between pale brown and grayish with a glassy shine. The round whorls are smooth with deep sutures. The apex is in many cases eroded. The ovate aperture is characterized by a marked lip edge.
The dark brown to almost black head shows white spots on the tentacles and on the neck and a black spot in front of each eye.
Habitat
Minimum recorded depth is 0 m.[2] Maximum recorded depth is 3.7 m.[2] The minute hydrobia can be found on seaweeds and mud close to the banks of brackish marshes and estuaries.
Biology
The minute hydrobia is a secondary host of a parasitic fluke, Homalometron pallidum. This has a complex life cycle with the adult phase being found in a small fish, the mummichog, Fundulus heteroclitus.[3]
