Colors and Some Morphological Traits as Defensive Mechanisms in Anurans
International Journal of Zoology, 2009 Anurans may be brightly colored or completely cryptic. Generally, in the former situation, we are dealing with aposematism, and the latter is an example of camouflage.

Frontiers in Ecology and EvolutionPhotorhabdus spp. are the only known terrestrial bioluminescent bacteria. We show that the bioluminescence produced by these bacteria reduces scavenging activity on the insect cadavers they colonize. Photorhabdus spp.

The evolution of imperfect mimicry in hoverflies [PDF]
, 2004 Ideas about the evolution of imperfect mimicry are reviewed. Their relevance to the colours patterns of hoverflies (Diptera, Syrphidae) are discussed in detail. Most if not all of the hoverflies labelled as mimetic actually are mimics.

Royal Society Open ScienceAposematic animals use conspicuous warning signals to advertise their chemical defences to predators. Selection by predators can favour conspicuousness and large pattern elements, which enhance predator avoidance learning.

Caudal Distraction by Rat Snakes (Colubridae, Elaphe): a Novel Behavior Used when Capturing Mammalian Prey [PDF]
, 1999 Caudal movement in snakes may serve either a predatory (e.g., caudal luring) or defensive (eg., rattling, aposematism) function. I describe a new behavioral pattern of tail movement in snakes. Gray rat snakes (Elaphe obsoleta spiloides) foraging on small
