Subfamily of primates
Loris
is the
common name
for the
strepsirrhine
mammals
of the subfamily
Lorinae
[1]
(sometimes spelled
Lorisinae
[2]
) in the family
Lorisidae
.
Loris
is one genus in this subfamily and includes the
slender lorises
,
Nycticebus
is the genus containing the
slow lorises
, and
Xanthonycticebus
is the genus name of the
pygmy slow loris
.
Description
[
edit
]
Lorises are
nocturnal
and
arboreal
.
[3]
They are found in
tropical
and woodland forests of India, Sri Lanka, and parts of
southeast Asia
. Their locomotion is a slow and cautious climbing form of
quadrupedalism
. Some lorises are almost entirely
insectivorous
, while others also include
fruits
,
gums
,
leaves
, and
slugs
in their diet.

Lorises, like most strepsirrhines, have a special adaptation called a "
toothcomb
" in their lower front teeth, which they use for grooming their fur and even injecting their venom.
[5]
Female lorises practice
infant parking
, leaving their infants behind in trees or bushes. Before they do this, they bathe their young with
allergenic
saliva
that is acquired by licking patches on the insides of their elbows which produce a mild toxin that discourages most
predators
,
[4]
though
orangutans
occasionally eat lorises.

Taxonomic classification
[
edit
]
The family Lorisidae is found within the
infraorder
Lemuriformes
and
superfamily
Lorisoidea
, along with the family Galagidae, the
galagos
. This superfamily is a sister taxon of Lemuroidea, the
lemurs
. Within Lorinae, there are ten species (and several more subspecies) of lorises across three genera:
