Predators taking adult alpine newts are snakes such as the grass snake, fish such as trout, birds such as herons or ducks, and mammals such as hedgehogs, martens or shrews. Under water, large diving beetles (Dytiscus) can prey on newts, while small efts on land may be predated by ground beetles (Carabus). For eggs and larvae, diving beetles, fish, dragonfly larvae, and other newts are the main enemies.[13]:73–77
