Male-biased predation of a fiddler crab
Article Abstract:
Research is presented concerning the investigation of the predation of fiddler crabs by great-tailed grackles through observation and predator models. The reason behind the male-biased predation of the birds is discussed.

Attractiveness of sand hoods built by courting male fiddler crabs, Uca musica: test of a sensory trap hypothesis
Article Abstract:
Mate-searching females may approach hoods because they resemble (mimic) other objects that crab approach to reduce their predation risk and two experiments were conducted to test this sensory trap hypothesis. Whether sexually receptive and nonreceptive female U. musica and nonreceptive female U. stenodactylus, a species that does not build structures, spontaneously approach hoods (replicas), stones, pieces of wood and shells is determined.

Hiding behavior in fiddler crabs: how long should prey hide in response to a potential predator?
Article Abstract:
A study was conducted to test whether males hide for longer when a predator-like stimulus approaches them directly rather than tangentially. The result reveals that prey can use stimuli prior to hiding to predict predation risk on re-emergence.
