Lampetra wilderi (American lamprey)

The Lampetra Wilderi fish is a fish belonging to the Lampetra family. It is also known as Wilder's lamprey. It is a fairly small fish, measuring about 10 cm long. It has an elongated and serpentiform body, with well developed pectoral and pelvic fins. Its color varies from dark gray to brown, with lighter spots on the belly.

The Lampetra Wilderi fish lives mainly in rivers and mountain streams, where it feeds on small invertbrates and fish smaller than it. He is able to move in fast water thanks to his powerful caudal fin, which allows him to propel himself quickly.

The Lampetra Wilderi fish is endemic to a single river in Germany, the Rur, where it is threatened with extinction. Indeed, the destruction of its natural habitat, pollution and overfishing led to a sharp decrease in its population. The Lampetra Wilderi fish is currently considered a critical endangered species by the International Union for Nature Conservation (IUCN).

Unfortunately, little is known about the reproductive and life habits of the Lampetra Wilderi fish, due to its rarity and the difficulty in studying it in its natural habitat. However, it is believed that young lampreys feed mainly on insect larvae and small crustaceans, while adults feed mainly on smaller fish.

In conclusion, the Lampetra Wilderi fish is a fascinating fish, but unfortunately threatened with extinction. Its survival depends on the protection of its natural habitat and the reduction of pollution and overfishing in the river where it lives.
