Excursion Apenheul 2021

Slide 1 - Diapositive

Write your names & class here.

Slide 2 - Question ouverte


Go to black-capped squirrel monkey



Don't forget to look around for other monkeys & apes!

Slide 3 - Diapositive

Black-capped squirrel monkeys can live in groups up to 200 individuals. Why is it an advantage to live in such a large group?

Slide 4 - Question ouverte

The squirrel monkey has a nasty habit. He pees on his own hands and feet! Then he smears the pee all over his body. His tail gets soaking wet. Its tail and its wet hands and feet leave a kind of stamp on the branches.

What do you think is the reason for this?

Slide 5 - Question ouverte

Watch the following video
If you are doing physical worksheet, go to YouTube and search for the following video:
'Doodshoofdaapjes springen

Slide 6 - Diapositive

Slide 7 - Vidéo

What do you think is the function of their tail after watching this video?

Slide 8 - Question ouverte


Go to the black howler monkey
(zwarte brulaap)

'Brulapen in concert'

Slide 10 - Diapositive

Slide 11 - Vidéo

It's all in the name: black howler monkeys can howl (brul) loudly. Their howl sounds like a loud burp and can be heard up to 2 miles (3 km) away!
The leader of the group starts and the rest joins in. As they howl, they often sit in a row.
What's the function of this roar? Name at least two reasons.

Slide 12 - Question ouverte

The body of a black howler monkey is adapted to be able to howl as loud as possible.
What adaptation do you notice when you look at his/hers body, that facilitates the loud howling?

Slide 13 - Question ouverte

Howler monkeys can seem a little lazy. Compared to other spider monkey species, they spend a large part of the day resting. They mostly eat leaves while other spider monkeys eat ripe fruits. Ripe fruits contain a lot of glucose, while leaves contain a lot less glucose.
Explain how the howler monkey's diet affects their daily activity and why.

Slide 14 - Question ouverte


Go to the bonobos

Don't forget to look around for other monkeys & apes!

Slide 15 - Diapositive

The bonobo is the closest to man of all apes.
Choose an active Bonobo and set a timer of 3 minutes:
write down what your monkey does in those 3 minutes.

Slide 16 - Question ouverte

Which of the things your monkey has done looks like the behavior of humans?

Slide 17 - Question ouverte

What differences between a bonobo and a human can you see? Write down differences in behavior (gedrag) as well as in appearance (uiterlijk).

Slide 18 - Question ouverte

Bonobos often have sex with each other. They do it to resolve a conflict (ruzie) or just to relax. Within a Bonobo group, everyone does it with everyone, except sons with their mothers.
This is quite different from most people. Why do you think people live in pairs of two people and are not as free as the bonobos?

Slide 19 - Question ouverte


Go to the ringtailed-lemurs



Don't forget to look around for other monkeys & apes!

Slide 20 - Diapositive

Ring-tailed lemurs are highly territorial.
What does that mean?
A
They defend their habitat against lemurs from other groups.
B
They do not tolerate any other animal species in their habitat.
C
Males and females only come together for mating.

Slide 21 - Quiz

The ring-tailed lemur's tail is longer than its body
A
True
B
False

Slide 22 - Quiz

Watch the following video
If you are doing physical worksheet, go to YouTube and search for the following video:
'Lemur stink fight Dudley Zoo'

Slide 23 - Diapositive

Slide 24 - Vidéo

Male ring tailed lemurs put smells, from glands in their bottoms, on their tail and wave it at rivals. It’s known as ‘stink fighting’!
They also use it to wave at the lady lemurs. What could be the function of this?

Slide 25 - Question ouverte


Go to the orangutans



Don't forget to look around for other monkeys & apes!

Slide 26 - Diapositive

Some adult male orangutans develop flaps of fatty tissue on both sides of their face - known as flanges - which develop when they're fully mature, at around 35 years old.
Find a male organgutan and take picture of him.

Slide 27 - Question ouverte

Orangutans find their food both on the ground and in the trees. Observe these monkeys for a while. Describe how they look for and eat food (which body parts and senses do they use for this)?

Slide 28 - Question ouverte

Compare the human teeth with those of the orangutan. Although the orangutan does not eat meat, it does have large canines (hoektanden). Why do you think this is?

Slide 29 - Question ouverte

Orangutans are smart animals. To challenge these monkeys, the Apenheul has added extra stimuli (prikkels) to the orangutan's enclosure. This makes them less bored.
What stimuli can you find?

Slide 30 - Question ouverte

Go to the gorilla's
Gorillas stick to a mainly vegetarian diet, feeding on stems, leaves and fruits. Western lowland gorillas, however, also have an appetite for termites and ants, and break open termite nests to eat the larvae. 

Slide 31 - Diapositive

Gorillas look a lot like us. Their digestive system (verteringstelsel) has a lot in common with ours. As you can see gorillas have big bellies. Their extra long intestines have to fit into them.
Why is it that they have such long intestines?

Slide 32 - Question ouverte

Gorillas live together in groups of 5 to 20 gorillas. There is one leader in the group, a male. He lives together with the females and their young. The gorilla leader makes sure there is peace in the group and protects them.
Observe the group gorillas for a few minutes and try to spot the leader. How can you recognize the leader?

Slide 33 - Question ouverte

Do you see any behavioral (gedrag) differences between the leader and the rest of the group?

Slide 34 - Question ouverte

Why is this useful when climbing?

Slide 36 - Question ouverte

What evolutionary benefit do spider monkeys gain from having a prehensile tail (grijpstaart)? 1

Slide 37 - Question ouverte

If you look closely, you will see a pink appendix (aanhangsel) in the females.
Search online for what this appendix is.
A
