a) Chemical communication
b) Visual communication
c) Sonic communication
d) Thermal communication


Female mate assessment of courting male fiddler crabs primarily involves visual communication through various visual signals, such as claw size and waving behavior.

Female mate assessment of courting male fiddler crabs involves visual communication. These crabs partake in elaborate courtship rituals where the size of the male's large claw and his waving behavior are examples of visual signals intended to attract females. This type of communication is critical for reproductive success, as females are typically more selective when choosing mates.

Male bowerbirds, for instance, build elaborate nests to attract mates, which is also a form of visual communication. Similarly, male birds with colorful plumage use these visual cues to attract females. In the animal kingdom, such visual signals are often accompanied by other forms of communication, including pheromone signals, tactile signals, and aural signals such as songs or calls.

For example, male crickets chirp to attract females, which is a type of aural signal. Birds, whales, and frogs use songs and calls for the same reasons, communicating crucial information for mating and reproductive purposes.
