What do otters eat where there is no fish?

Abstract

Recently, Clavero et al. (2008) found a negative relationship between the stability of water courses and the occurrence of fishes in otter diet. We studied otter diet in a place of mainly temporary water in form of small ponds and streams strongly dependent on rainfall. Our results constitute the extreme of the gradient of water instability, where otters do not prey upon fish but depend on crayfishes and diving beetles to survive.
