Nocturnal

Luminophobos

Nightipherous

Nicturian

NEXT>

2. Another type of animals that prefer the dark are troglobites. What is a troglobite? Hint

An animal that eats in one bite

An animal that lives in caves

A venomous animal

A very common fossil animal

NEXT>

3. Deep sea creatures also live in the dark. So a deep sea creature is a creature that lives where? Hint

On the ocean floor

Only on oceanic trenches

Below one hundred meters

Below the photic zone

NEXT>

4. Which is not an advantage of being nocturnal? Hint

Higher reproduction rate

Lower resource competition

Avoiding predation

Water conservation

NEXT>

5. Better eyes, better ears and better noses - nocturnal animals usually have highly developed senses.

True

False

NEXT>

6. Troglobites have highly developed eyesight.

True

False

NEXT>

7. Another adaptation seen in troglobites is to do with colouring. How are most of them coloured? Hint

They mostly have no pigmentation

As colour does not matter they are any colour

They are black to blend with their surroundings

Most of them shine in the dark

NEXT>

8. Deep sea creatures live in a very harsh environment. Which is *not* a problem that these creatures must overcome? Hint

Extreme pressure

Lack of resources

Lack of light

Great variations in temperature

NEXT>

9. A very common characteristic in deep sea creatures is that a lot of them create light. What is this called? Hint

Quiz Answer Key and Fun Facts

1. An animal who is more active at night is described as what?

Answer: Nocturnal

Nocturnal animals are active during the night and resting during the day.

2. Another type of animals that prefer the dark are troglobites. What is a troglobite?

Answer: An animal that lives in caves

Troglobites are animals adapted to living in the dark parts of cave systems.

3. Deep sea creatures also live in the dark. So a deep sea creature is a creature that lives where?

Answer: Below the photic zone

Deep sea creatures live below the photic zone of the oceans, defined as the zone where there is sufficient sunlight for photosynthesis to occur.

4. Which is not an advantage of being nocturnal?

Answer: Higher reproduction rate

Avoiding or enhancing predation, water conservation in arid biomes and using niche differentiation as a form of resource competition are all advantages of nocturnal life.
A higher reproduction rate has no bearing as to whether an animal is nocturnal or not.

5. Better eyes, better ears and better noses - nocturnal animals usually have highly developed senses.

Answer: True

In poor light conditions you can choose your menu. You can mix any amount of better eyesight, better hearing and better smelling or else you're in the menu.

6. Troglobites have highly developed eyesight.

Answer: False

Where there is no light there is no sight. Most troglobites are either eyeless or with only vestigial eyes.

7. Another adaptation seen in troglobites is to do with colouring. How are most of them coloured?

Answer: They mostly have no pigmentation

Loss of pigmentation is one of the most common characteristics of troglobites. There is no need for colour when colours can't be seen.

8. Deep sea creatures live in a very harsh environment. Which is *not* a problem that these creatures must overcome?

Answer: Great variations in temperature

Extreme pressure, lack of light and lack of resources (food and oxygen are scarce due to lack of photosynthesis) are the major obstacles for deep sea creatures. As for variations in temperature, most deep sea environments are very stable in terms of temperature, even when these temperatures are extreme.

9. A very common characteristic in deep sea creatures is that a lot of them create light. What is this called?

Answer: Bioluminescence

Bioluminescence is the ability to create light. This is done to attract prey, mates or simply light the way.

10. Of the lists of animals below, which one is only composed of animals that live in the dark?

Answer: Humpback anglerfish, naked mole-rat, eyeless huntsman spider

To make this explanation short, just the wrong ones:
Hyenas are crepuscular not nocturnal, blue whales are not deep sea creatures and the cave swallow is not a troglobite.
