DescriptionBrook Lampreys nesting - Lampetra planeri 1.jpg | This is my first Lamprey photo - at this stage there are only three of the group of five assembled at the nest site. A little predatory fish is hanging around hopefully but it didn't like me watching and soon left them alone. Immature lampreys are blind and live between three and seven years in burrows in the mud. They metamorphose into sighted adults, swim upstream, have a nesting party and die. They are some of our most primitive vertebrates: they have a cartilage skeleton like sharks but lack gill covers and jaws. In this shot you can see the row of seven gill holes behind the eye. They pick up stones with their sucker mouths and move them around to build a nest for their eggs. European Brook Lampreys - Lampetra planeri, 11th March 2011, in a brook beside the River Itchen at St Cross, just south of Winchester, Hampshire, UK. | ||
