Primates Observed

Non-Primate/ Animal

Saki Monkey

Western Gorillas

Orangutan

Ring Tailed Lemur

Humboldt Penguin

Locomotion

Leapers

Knuckle Walking

Arboreal Quadruped

Terrestrial Quadruped

Biped, Tobogganing

Often leaped from one branch to the other.

Mostly used its knuckles to move one place to the other.

The orangutan used its arms and legs to move from branches.

Some of them were on trees but most of them were on the ground socializing with one another.

Most waddled bipedally. To move faster, they slide on their bellies using their flippers to steer.

Inside or enclosed

The saki monkey moved through branches by leaping. Unless the branch is really far, they would just stay on the branches or move quadrupedally if food was near.

One male leaped by pushing its body off the ground with his hind legs and stretch his arms up a bit before landing on the branch with its feet.

Saki monkeys run/move really fast because they push themselves off the ground really well.

The western Gorilla supports its weight by its legs and knuckles.

You can distinguish males from females easily because females would sit with their offspring. While males usually knuckle walk around.

Their arms also look longer than their legs.

Males seem to have longer radius than humerus. It also seems their lower arm looks bigger/wider than their forearm/humerus.

Their arms look considerably longer than their legs.

They would reach branches from above with their hands and use their feet to help lifting itself off.

Their hands and fingers look really long which helps them grab or wrap their hands on branches firmly.

They also sat on their bottoms while they ate.

They can also hang on branches for several minutes.

They walk on all fours when on ground.

Their legs look longer than their arms.

This is observed mostly when they walk on all fours, due to their upper body being closer to the ground than their lower body.

When in trees, they leap from one branch to the other.

When they run on all fours, their hind legs seemed to be the primary source of force.

The humboldt penguin walks or waddles mostly on both feet.

The flippers help them keep balanced because when they walk, their flippers seem to be outward on its sides.

To move faster in the encloser, they would slide on their bellies then dive.

They also use their flippers to steer when they slide on their bellies.

Behavior

-At 12:30 pm (Partially sunny)

2 saki monkeys were ‘communicating’ with each other by making sounds at each other.

-At 12:36 pm

(Partially sunny)

2 saki monkeys were grooming one another.

-At 12:42 pm

(partially sunny)

1 saki monkey was able to sit on the branch firmly because of its long toes. (It tried to reach for more seeds from the keeper)

-At 12:56 pm

(partially sunny)

1 saki monkey was ‘leaping away’ from another saki monkey. Their long legs gave them the ability to leap really high from one branch to the other at a fast rate as well. It looked like they were flying.

Key Anatomical Features:

1. Long legs

2. Small stature (12-16 in.)

-At 1:18 pm

(Sunny)

1 gorilla is grooming another gorilla that was laying on its lap.

-At 1:40 pm

(partially sunny)

Some gorillas moved out from the shade and into the open space.

-At 1:55 pm

(sunny)

Gorillas that were out in the open were close to each other eating, sleeping or grooming.

Key Anatomical Features:

1. Arms are longer than legs

2. They have large or thick knuckles.

3. Big/large in stature.

-At 2:00 pm (sunny)

1 baby orangutan was hanging on a branch with both its hands while using its legs and toes to grab another branch that had leaves it munched on.

-At 2:15 pm (Sunny)

1 orangutan sat down on a table and started to crack a coconut it had on its hands several times until it could drink the juice from it.

-At 2:30 pm

(sunny)

1 orangutan (female) had an offspring wrapped around its body, breastfeeding. She was sitting down during this.

Key Anatomical Features:

1. Long arms.

2. Relatively shorter legs compared to arms.

3. Long fingers and toes.

-At 2:40 pm

(partially sunny)

Most lemurs were on branches using their hands to munch on leaves. Some went down by using their hands and feet to slowly move down logs or branches.

-At 2:55 pm (partially sunny)

Most lemurs on the ground walked on all fours. They usually walked in groups of 3 or 4.

-At 3:00 pm

(sunny)

They can also move along branches on all fours unless the branch that they’re trying to go to is far then they hop lightly.

Key anatomical features:

1. Shorter arms.

2. Longer hind legs.

3. Small in stature.

4. lightweight.

-At 3:25 pm

(at an enclosed area)

Most penguins were just standing and giving out calls.

-At 3:40 pm

A handful of penguins kayed on their bellies and started sliding away and diving into the water.

-At 3:40 pm

They’re able to penetrate the water and swim really fast. Their webbed feet serve as an engine for them.

Key Anatomical Features:

1. Beak

2. Flippers

3. Webbed Feet

4. Thick or dense, small feathers
