Overview

Occurrence ID	LC000053000A329S
Basis of record	Human observation
Scientific name	Mercenaria mercenaria (Linnaeus, 1758) - Hard-shelled clam
Licence	CC-BY
Record Date	1966-06 (Month)
Locality	Lepe Beach; Hampshire.
Location	Grid Reference: SZ460985 Latitude: 50.784252028474 Longitude: -1.3488497950478
Recorded by	B. Lucas
Identified by	B. Lucas
Identification verification status	Accepted - correct
Occurrence remarks	One large nearly perfect double shell found towards Calshot. In 1966 these were found to have spread from the warm water given out by the power station at Marchwood (GR396114) to the Calshot area; But I think these are the first records for the Lepe-Calshot streach of shore. They have also spread across Southampton Water to Woolston; down to the Weston shore and on towards Hamble Point.
