Summary

Description

Lampreys belong to a group of vertebrates known as Agnatha which means 'jawless fish'. Their mouth is a toothed circular sucking disk. They have long elongated eel-like bodies. They can also be recognised by their gills which open directly to each side of the head in the form of a line of seven gill holes behind the eye. The back and sides of Lampetra fluviatilis have a uniform colour pattern consisting of a brown dorsal colouring, golden yellow sides and a white ventral colouring. It may reach up to 30-40 cm in length.

Recorded distribution in Britain and Ireland

Occurs close to the coast throughout the UK and Ireland, migrating upstream many British and Irish rivers in August to spawn .

Habitat

Lampetra fluviatilis is a demersal and anadromous species found in a wide range of riverine and coastal habitats.

Identifying features

  • Long eel-like body up to 30-40 cm in length.
  • Brown dorsal colouring, golden yellow sides and a white belly; no marbled colouring.
  • Circular sucking disk for a mouth with sharp teeth.
  • Seven conspiculous gill holes in a line behind the eye.
  • Scales, paired fins and gill covers are absent.

Additional information

Relatively easily distinguished from the sea lamprey Petromyzon marinus by its considerably smaller size and uniform colour pattern. It can be distinguished from another species, the brook lamprey, Lampetra planeri by its much larger size (the brook lamprey rarely reaching over 18 cm in length) and the two distinct dorsal fins (the brook lamprey only having one continuous dorsal fin). Schreiber and Engelhorn (1998) however, found very little difference in the DNA content between both species suggesting Lampetra fluviatilis may just be an anadromous form of Lampetra planeri.
