Primates are phylogenetically divided into those with a rhinarium, the Strepsirrhini (the prosimians: the lorises, and the lemurs), and those without a rhinarium, the Haplorhini, (the Simians: monkeys, apes, and humans). In place of the rhinarium, Haplorhini have a more mobile, continuous, dry upper lip.
Do Old World monkeys have a rhinarium?
Nose. The external morphology of the nasal region in higher nonhuman primates is characterized by the lack of a rhinarium, lack of a primitive-type philtrum, and an upper lip which is continuous across the midline inferior to the nasal septum.
What animals have rhinarium?
Examples of mammals that have rhinarium include streptorrhines (i.e. lemurs, lorises, pottos, and galagos), cats, dogs, elephants, and walruses.
Do lemurs have a rhinarium?
Lemurs share resemblance with other primates, but evolved independently from monkeys and apes. … As with all strepsirrhine primates, they have a “wet nose” (rhinarium). Lemurs are generally the most social of the strepsirrhine primates, and communicate more with scents and vocalizations than with visual signals.
Which of the following primates have a rhinarium quizlet?
Includes lemurs, lorises. The prosimians have a rhinarium. suborder under primates. Includes tarsiers and anthropoids.
Do tarsiers have rhinarium?
However, it is now generally accepted that the tarsiers make up the earliest haplorhine group. … For example, their small body size and grooming claws are somewhat strepsirrhine traits, while the absence of a rhinarium is quintessentially haplorhine.
Do all primates have forward facing eyes?
All living primates have forward-facing eyes (Figure 1, Johnson, 1901, Cartmill, 1992). In this respect, primates more closely resemble cats and owls than many other mammals (e.g., squirrels or gazelles). Having forward-facing eyes gives primates a wide field of binocular vision (Heesy, 2004, 2009).

Do ring tailed lemurs have rhinarium?
Lemur hind legs are longer than the front, more pronounced in arboreal species. The muzzle has touch-sensitive vibrissae (whiskers) and the nose is a bare, wet rhinarium. … Unlike other lemurid species, the Ring-Tail has a tapetum lucidum.
Are tarsiers Platyrrhines?
Haplorrhines are split into three groups: 1) the catarrhines, old world monkeys, apes, and humans, 2) the platyrrhines, new world (South American) monkeys, and 3) tarsiers. Apes are found in Africa and South East Asia, and tarsiers are found only in South East Asia.
Is a sloth a primate?
Sloths are mammals, but they aren’t primates or marsupials – though the groups do share some similarities. Koalas, for example, are marsupials that live in trees, eat leaves and have slow metabolisms. But sloths and koalas developed these traits independently of each other. The two aren’t closely related.
Which of the following are hominoids?
Apes (Hominoidea) are a group of primates that includes 22 species. Apes, also referred to as hominoids, include chimpanzees, gorillas, orangutans, and gibbons. Although humans are classified within the Hominoidea, the term ape is not applied to humans and refers instead to all non-human hominoids.
What superfamily has Bilophodont molars?

Are tarsiers Frugivorous?
All tarsiers are totally faunivorous: they eat insects, arachnids, and small vertebrates such as snakes and lizards. There is evidence from both naturalistic and captive studies of considerable differences in social behavior among and within species (Gursky, 2011).
Are tarsiers quadrupedal?
bancanus able to leap over 5 m (16.4 feet) (Niemitz 1983). Other forms of locomotion include bipedal and quadrupedal climbing, quadrupedal walking, clambering and hopping (MacKinnon &, MacKinnon 1980, Niemitz 1984c, Crompton &, Andau 1986, Dagosto et al. 2001).
Are gibbons Catarrhines?
Catarrhines include gibbons, orangutans, gorillas, chimpanzees, and humans. Two superfamilies that make up the parvorder Catarrhini are Cercopithecoidea (Old World monkeys) and Hominoidea (apes).
Why primates have front facing eyes?
Forward facing eyes allow for binocular or stereoscopic vision, which allows an animal to see and judge depth. Predators need this depth perception to track and pursue prey. … Monkeys also have forward facing eyes that give them depth perception needed to swing and leap in their tree top habitat.
Which bird has eyes facing forward?
Owl has eyes in front of its head (like in humans).
Do all primates have grasping hands?
Primates have five fingers on their hand and five toes on their feet. … Most species have fingernails instead of claws and they have touch-sensitive pads on each of their digits. The hands and feet of all primates, except for humans, are designed for grasping.
What are convergent orbits?
Orbit convergence is isometrically related to binocular visual field overlap across mammals. In general, these data indicate that reorientation of the bony orbit such that they face the same direction is highly correlated with expansion of the size of the binocular zone of the visual field.
Do all primates have binocular vision?
Many primates have color vision comparable to our own. All have binocular vision with fields of view that significantly overlap, resulting in true three dimensional (3-D) depth perception or stereoscopic vision.
What is an eye orbit?
The orbit is the bony cavity in the skull that houses the globe of the eye (eyeball), the muscles that move the eye (the extraocular muscles), the lacrimal gland, and the blood vessels and nerves required to supply these structures.
