Social Behaviour and Communication in Elephants - 3
Memory and Recognition
Elephants living in big social organisations require good memory and recognition capabilities
due to the fluid society in which they live. This is because they are constantly separating
from the family unit and at the same time, meeting family and non-family members on a daily basis,
so need to be able to recognise kin from non-kin; Carol Buckley witnessed two individuals that
reunited after 23 years of being apart. (Granli et al 2006)

Elephants have large brains and their cerebral cortex is highly developed which enables them to
achieve a greater potential of learning and retaining this information for long
periods of time. (Granli et al 2006)
This gives the elephant a level of intelligence which
other land mammals may not have. They are also able to see their reflection in the mirror, a skill
that only humans and some primates are able to do. (See Fig 6)
One important aspect of recognition and memory in elephants is to avoid inbreeding depression
from occurring. Apparently, elephants are able to distinguish paternal kin from non-kin by phenotype
matching using olfaction, but the mechanism is still unknown.
The dispersal of one sex in elephants,
usually males, is vital to prevent inbreeding depression in addition to their ability to
recognise kin and avoid mating with them. (Moore, 2007)
Elephants' efficient sense of smell is also used to allow them to make mental maps of their
conspecifics' whereabouts and thus track the location of their family members simply by sniffing
their urine. (McKenna, 2007)
One study presented African elephants with urine samples that were either kin or unrelated individuals,
situated in locations that were either unexpected or predictable. The elephants' behaviour and reactions
to these cues illustrated that they could recognise up to 17 females and 30 family members. (Bates et al 2008)
Not only do their senses provide the means for recognition and memory, but their family unit supplies the
teaching blocks for young elephants. Calves watch their mothers and older sisters during their days in the bush
and learn from them with regards to finding food and water i.e. using their trunk to dig into the ground to
reach the water table.
They also make note of how the adults react and behave towards different individuals and they retain this
information as a guide during their adulthood. Most actions observed by elephants have been learned during
childhood which illustrates their good memories.
One can conclude therefore that elephants are extremely intelligent mammals due to their
very advanced sensory systems and social structure.
If elephants did not have such powerful sense of smell, touch and the like, their social organisation would not
be as specialised as it is today with regards to communication and dispersal.
It is also their ability to
learn from interacting with individuals in their intricate social grouping and to recognise important cues
for long periods of time which further adds to their intelligence and complex social network.
