Mongooses and Meerkats both belong to
the family herpestidae but the Mongoose (known as a mangusto in Portuguese) is
the only one you are likely to see here in Portugal.
They are long, furry creatures with a
pointy face and a bushy tail and are not rodents, but a carnivore. (For those
interested, the correct plural of ' mongoose ' is not 'mongeese' but ‘mongooses
'. The reason? The two words mongoose and goose have completely different
origins, and therefore different plurals.)
The Egyptian Mongoose is confined to
southern Portugal and is a species native to the coastal regions along the
Mediterranean Sea between North Africa and Turkey, and Africa.
They move at a brisk gallop or a low
slink and are not easily seen as they make use of dense cover. Whether they
were introduced or native to the Iberian Peninsula is in some doubt according
to Wikipedia.
Some are solitary for nearly their
entire lives, and others live in large groups, which are known as packs, mobs,
or colonies, depending on the species. Often, large packs can number up to 50
individuals, and in large packs, group care of the young is often seen.
Humans have long admired mongooses for their
ability to kill venomous snakes. This trait was also famously dramatized by
Rudyard Kipling in his 1894 story "Rikki-Tikki-Tavi," in which a
mongoose saves a human family from villainous cobras.
They are formidable opponents for snakes
largely due to their speed and agility, which helps them launch quick attacks
when they sense an opening. But some species also have an extra advantage -
they've evolved a resistance to snake venom, allowing them to keep fighting
even after receiving a bite that would kill most animals their size.
They are not immune to the venom, but
thanks to special mutations in their system, the neurotoxin has difficulty
binding to their nicotinic acetylcholine receptors, rendering it less
effective.
They are mature between 9 months to 2
years of age and live from 6 to 10 years in the wild. They will stand erect to
look around for danger, which brings us to Meerkats, almost instantly
recognised by their ‘sentinel’ guarding behaviour.
Meerkats
Meerkats (in Portuguese, suricata) live
in all parts of the Kalahari Desert, in much of the Namib Desert and
south-western Angola and in South Africa, and they are the sole member of the
genus Suricata, a weasel-like animal that are also part of the mongoose family.
We know quite a bit about these cute
creatures, thanks to nature programmes where their lives have been documented
in detail, and a certain TV ad features them, which has made them instantly
recognisable.
The sentinel role is performed by a
helper or a non-breeder, and having remarkable eyesight, he or she is on the
lookout by constantly watching for possible predators and potential threats
while the group is away from the burrow, and will sound the alarm by producing
a distinct bark. This position rotates amongst different members of the group
in no particular order.
They are smart too. A study at St
Andrew's University, Scotland, found meerkats use complex coordinated
behaviour, which rivals that of chimps, baboons, dolphins and even humans. They
solve tasks with help from their ‘mob’ but also through independent thought,
and the study saw meerkats engaged in a wide variety of social and solitary
behaviours to solve tasks.
Meerkats may look adorable with their
big eyes and family orientated behaviour, but they have developed a technique
for handling the venom found in scorpions, which they eat.
Cleverly, the meerkat zeroes in on the
tail and bites off the scorpion's stinger and discards it. Without its tail the
scorpion can’t deliver their venom, but there is still venom on its
exoskeleton, and to combat this, meerkats have learned to rub scorpions in the
sand to remove any remaining venom.
Interestingly, despite living in the
desert, meerkats do not need extra water in their diets, getting all the
moisture they need from the insects and grubs they eat, whereas us mere mortals
would die within 3 – 5 days without additional water.

First time I saw mongooses was in Alvaiazere. Too big to be ferrets, too small to be a fox. Quick as well!
