The almost invisible league: crypsis and association between minute fishes and shrimps as a possible defence against visually hunting predators Neotropical Ichthyology
Carvalho,Lucélia Nobre; Zuanon,Jansen; Sazima,Ivan.
Camouflage is one of the most widespread defence modes used by substrate-dwelling animals, whereas transparency is generally found in open-water organisms. Both these defence types are regarded as effective against visually guided predators. We present here three assemblages of similarly-sized freshwater fish and shrimp species which apparently rely on camouflage and transparency to evade some of their potential predators. In one of the associations, there is a transition from cryptic colours and translucency to transparency of the component species according to the position each of them occupies in the habitat. The likeness between the fishes and the shrimps is here regarded as a type of protective association similar to numerical or social mimicry....
