How well do you know South Africa V?

Question

Ready or not, here's the next batch. The previous lot was a bit easy (for some), so I had to make it a little harder this time...

1. The female of which invertebrate found along the SA coast, looks after her her eggs until they hatch?
2. Who was a mission teacher before greater claim to fame?
a) Olive Schreiner
b) C.J. Langenhoven
c) Albert Luthuli
3. What is the connection between the saw-edged jelly weed found along the SA coast, and ice cream?
4. Which 2 inventors from KwaZulu-Natal developed the world's first automatic microwave popcorn vending machine?
5. Which lightweight mammal, found in SA and weighing in at 3-4 grams adult weight, is a contender for the world's smallest mammal?

Blouspook, if I just told you the answers, it wouldn't be a question now would it. The "insane" people who would know no.1 are probably those who have an interest in life that stretches a little further than their dog and the people in the Huisgenoot.
If you don't like the question, then don't answer it. Some do.

Answer 5

Hey, Vango, you evidently know all the answers, so why not just tell us and in that way brag with your superior knowledge?
The shrew ( skeerbekmuis) is the answer to 5. Any one of question 2 could fit the bill.
The answer to 3 could be awe inspiring and why any sane person would know the answer to 4 is beyond me. Pray tell.
