Arctic charr (Salvelinus alpinus) is generally considered an inferior piscivore compared to
brown trout (Salmo trutta). However, we demonstrate that a recently described profundal
spawning piscivore PP-morph of Arctic charr in a subarctic lake has evolved typical piscivore
traits (ie large jaws, robust skulls), similar to the co-occurring brown trout but different from
the sympatric littoral spawning omnivore LO-morph of Arctic charr. A few large-sized LO-
morph, most large-sized PP-morph and trout constitute the piscivore guild, but they differed …
