Scientific name:
Lampetra planeri

Natural spread:
Europe

the small one hardly 15cm tall, small-finger-heavy brook-lampreys lives predominantly in small brooks and rivers.

It spawns from May to June. Both sexes beat oblong pits into the sandy reason when spawning. The female sets aside the eggs into these deepenings. The male soaks firmly at the head of the female and inseminates the eggs. The larval-time amounts about. 4-5 years. During this time, the larvae live mainly from organic rests. After conversion from the adult lamprey, the suction-organ develops. The digestive-section and the animal waste away on that occasion becomes sexually mature.

After the reproduction, the lampreys perish. On the basis of the long larval-time, that among other things means a continuous fight of the animals with environment-influences, the animals are endangered already in the continuance or even threatens from the extinction regionally.
