St.Lucia
Anole (Anolis luciae)

Lizards, lizards
everywhere; in our homes, work places and
yards. Do we consider them as nuisances or
treat them as another animal beautifully created
by God? Whilst going about our daily activities
we do come into contact with lizards but can
we tell the difference in the species?
Commonly known
as zanndoli, the St.Lucia tree lizard is endemic
to our island scientifically known as Anolis
luciae. Although there are two species from
the anole family their body markings differ
which makes them easier to identify. The male
anole may reach a length of 91mm from snout
to the base of its tale. There are many colour
variations from pale apple green to dark brown
depending on if its habitat is wet or dry.
The bark may or may not have dark markings
but no ring is found round the eye however,
the area around the eye may be white, blue,
or green. The underside is usually white or
yellowish. The dewlap or the bulge which forms
in the throat often used to intimidate predators
is sometimes grayish yellow or plain grey
to brick red with green scales.
The females
are shorter in length (63 mm) and duller in
colour to their male counterparts. The iris
is turquoise, blue or dark brown which brightens
the female.
The St. Lucia
Anole is not habitat specific and is widespread
on St Lucia and the offshore islets. The females
and juveniles tend to be found frequently
on the ground, where females lay and bury
one or two eggs in a shallow nest, whilst
the males perch higher.


In
this case we have good news. For once we have
an endemic which is not threatened or vulnerable
but it has been observed that the numbers
are fewer on plantations or in areas which
have been disturbed or degraded by human activity
or natural disasters.
The
zanndoli is deemed a predator to crawling
creatures such as spiders, grasshoppers, cockroaches,
ants and insect larvae off which it feeds.
They wait patiently for their prey which could
be caught on trees, walls and the ground.
The
Anolis co-exists with two introduced anole
species: A. extremus and A. wattsi from Barbados
and Antigua respectively, but it appears to
be resisting competition, and the two invasive
species are restricted mainly to areas around
Castries.
Though
this endemic species is not on the brink of
extinction, we should not let our guard down
when it comes to protecting and treasuring
species found on our island, creatures which
make our biodiversity rich and unique.
