Think about external fertilisation.
What do you think might be some of the problems associated with external fertilisation?
When the animals release sperm and eggs into the water, some of the eggs never get and much of the sperm goes to . The developing eggs and the young animals are vulnerable to being by predators.-

Question 4 of 9
4. Question
To overcome some of the problems associated with external fertilisation, many animals have adopted internal fertilisation.
However, mammals have gone one stage further and the male has developed an organ that actually introduces the sperm inside the female.
What is the name of this organ?
The male mammal has developed a which passes sperm right inside the female’s body.-

Question 5 of 9
5. Question
Some animals face a particular problem when they come to reproduce.
For example, reptiles lay soft-shelled, air-breathing eggs. That is a problem for a particular marine reptile – it has to leave the sea and clamber up the beach to lay its eggs. That leaves both the adult female and the eggs vulnerable to predation.
Then, once they’ve hatched, the young have to try to reach the sea without being caught.
Any idea what this marine reptile might be?
The tracks in the picture are made by a female as it clambers up the beach, digs a hole for its eggs, and tries to return to the sea.-

Question 6 of 9
6. Question
We’ve looked at whether animals choose internal or external fertilisation, but what about their young?
Some develop outside the body (and hatch from eggs) and some develop inside the female and are born.
Try to sort out these youngsters into ones that ‘hatch’ and ones that are ‘born’.

Question 8 of 9

Many male animals develop special colours or adaptations (like a stag growing antlers) to encourage females to breed with them.
They often perform elaborate dances or fly in a special way.
Do you know what this behaviour is called?

Question 9 of 9
9. Question
Let’s wrap up this activity by sorting out animals according to where they develop.
What you have to do is to match each animal with the way in which its eggs are fertilised (internal or external) and also whether the young develop inside or outside the body.
[Hint: you’d match ‘frog’ with ‘external fertilisation & external development’.]
