communication
In biology, the signalling of information by one organism to another, usually
with the intention of altering the recipient's behaviour. Signals used in
communication may be visual (such as the human smile or the display of
colourful plumage in birds), auditory (for example, the whines or barks
of a dog), olfactory (such as the odours released by the scent glands of
a deer), electrical (as in the pulses emitted by electric fish), or
tactile (for example, the nuzzling of male and female
elephants).

Annelid Worms
The earthworms use touch to communicate and influence each other's behaviour,
according to research published in the journal Ethology.
By doing so the worms collectively decide to travel in the same direction as
part of a single herd.
The striking behaviour, found in the earthworm Eisenia fetida, is the
first time that any type of worm, or annelid, has been shown to form active
herds.

insects
Numerous animals use vibrations propagating through a substrate to communicate
with conspecifics, predators or prey. This mode of communication has reached
extraordinary heights in insects and spiders, where it is both highly
sophisticated and remarkably diverse in function.

Frogs
and toads
produce a rich variety of sounds, calls, and songs during their courtship and
mating rituals. The callers, usually males, make stereotyped sounds in order to
advertise their location, their mating readiness and their willingness to defend
their territory; listeners respond to the calls by return calling, by approach,
and by going silent

is any transfer of information on the part of one or more animals that has an effect on the current or
future behaviour of another animal. The study of animal communication —
sometimes called zoosemiotics (defined as the study of sign communication or semiosis in animals; distinguishable from anthroposemiotics,
