Lake Constance (47° 38' N, 9° 22' E) is a deep (max. depth 251m) and large (surface area 536 km ) postglacial lake in Central Europe. Originally, it harboured two charr species - Salvelinus umbla and S. profundus. The first is a medium-sized, colourful, winter spawning charr, which is widespread across Central European lakes, the second a small, pale, summer spawning, deepwater charr, which is endemic to Lake Constance (Schillinger 1901, Kottelat and Freyhof 2007). S. profundus has exceptionally large eyes and the upper jaw strongly overlaps the lower jaw.
