On the other hand, if a rat forages in the leaves and makes a sound that attracts a predator, the sound itself is a cue and the interaction is not considered a communication attempt.

In addition to camouflage and appearing larger in the face of a threat, squids use color, patterns, and flashing to communicate with one another in various courtship rituals. Caribbean reef squid can send one message via color patterns to a squid on their right, while they send another message to a squid on their left. [9] [10]
Squid are capable of rapid changes in skin color and pattern through nervous system control of chromatophores. [38] In addition to camouflage and appearing larger in the face of a threat, squid use color, patterns, and flashing to communicate with one another in various courtship rituals. Caribbean reef squid can send one message via color ...
Some male squids, mainly deep-water species, have instead evolved a penis longer than their own body length, the longest penis in any free-living animals. It is assumed these males simply attach a spermatophore anywhere on a female's body. [115] An indication of sexual maturity of females is the development of brachial photophores to attract mates.
The squid floats along the water upside down with one eye aimed at the ocean floor and the other looking above. Named for its bright red color, the squid has red-tinted photophores (light-emitting ...
Whistling is used by animals such as prairie dogs to communicate threats, with prairie dogs having one of the most complex communication systems in the animal kingdom. Prairie dogs are able to communicate an animal's speed, shape, size, species, and for humans specific attire and if the human is carrying a gun . [ 41 ]
Bigfin squids are a group of rarely seen cephalopods with a distinctive morphology.They are placed in the genus Magnapinna and family Magnapinnidae. [2] Although the family was described only from larval, paralarval, and juvenile specimens, numerous video observations of much larger squid with similar morphology are assumed to be adult specimens of the same family.
