Larvae of Moor frog Rana arvalis

  • no external gills (tadpole)
  • eyes not prominent
  • underside not black to grey, belly often copper dotted
  • tail fin not reticulated
  • back without tranparent edge
  • the colour of the back varies, usually dark with tiny metallic dots
  • upper crest extends up to about the middle of the trunk, without big black spots
  • From a length of approximately 10 mm in the mouthparts the three lower rows of labial teeth are recognizable in the mouthparts with a strong lens (photo) so distinguishable from Common frog.
    In order to see these separately a carefully dabbed drop of saliva can be of help.
  • Total length:
    up to about 45 mm
