The okapi is doing the same? what is the ratio of his neck and leg lenght?
I thought the giraffe had to splay its legs because the neck is to short. Might that be possible in the okapi?


As far as I know Jaap, that is the case. Because of the sloping back,
the ratio of neck and leg length, also the narrow shoulders, forces the
Okapi to splay it's legs whilst drinking as well.

Perhaps someone else can add to this.

Jaap, my understanding is the same as Siobains. In terms of drinking the giraffe and the okapi are perceived to actually have necks that are short relative to their legs and chests thus forcing them to splay or bend their legs to reach the ground.

BTW, thanks for this question as it has led me to some interesting insights into the giraffe and okapi :thumbs_up:

The trees might just work that way.. but why? Normally there should be a reason right? Like flowers need to be good visible and easy to get to. The leaves will have to come shortly after to help providing the new growing fruit/seeds with 'food'.


Sorry - you're quite correct Jaap. The reason that many decisous trees flower before leaf appearing appears to be to increase pollination rates either through wind because the flowers are more open or because the flowers are visible to insects as there is no leaf cover.

Here a new question on the same subject and a hypothese.

Do Okapis shake their heads also after drinking? Do they have a same build of their head as the giraffe (long and narrow)

I have seen impalas drinking water and afterwards licking their lips.
Elephants will swing the tip of their trunk to get rid of the last bit of water.
We humans use our hands to wipe after drinking...
Now here the hypothese:
The long muzzle of the giraffe does not allow for the giraffe to suck up the last bit of water in the muzzle when stopping with drinking. They shake their heads to get rid of the remaining water. They can probably swallow the water only when they lift their head above horizontal..

I know its a long way to suggest.... But what else could it be... :huh:

Jaap, following on your hypotheses why would the giraffe not just use its tongue to rid itself of the last bits of water?

The okapi head looks remarkably similar to the giraffe and they even tend to browse the same way, Again, I don't have any facts on whether they shake their head after drinking - might be worthwhile dropping an email to the research centre!

:hmz: Point taken...
Maybe they just like to toss the water all around. :mrgreen:

I'm beginning to think the same - just like a dog likes to shake it's head.

I wonder if we're trying to read too much into every little bit of animal behaviour - the human need to know why each time we see something different? :hmz: :huh:

Jambo Formites,
How are you all?
This is my question concerning about an ant-lion. They live in two stages, larvae + adult stage. At what time do they lay the eggs in adult stage? Do they take care of the youngs? (parental care) because they dont have longer life in adult stage.
thanks a lot Formites

Hello Furahini, good to have you back. :D

The average lifespan of an adult antlion is between 20 to 25 days, some
may live longer.

After the adult antlion emerges from it's cocoon it's sole
purpose is to reproduce, they eat very little, if at all. They cannot fly
at first, so they usually climb a plant or tree and wait for their wings to
expand and harden which usually takes about 20 minutes, she will then
find a mate, once this has successfully been done, she will lay her eggs
in the sand, she lays about 20 eggs each one separately. When she is
finished she will often find another mate so she can lay eggs once more.

There is no parental care. What sometimes happens is, when laying her eggs
she does so near other active larvae pits and could be captured and eaten
by the larvae.

Jambo Fuharini, Eric and all the guides of Selous, I am very well, thank you for asking. :D
I always enjoy talking to you, so it is a pleasure to answer your questions as best I can. :thumbs_up:

Perhaps when you have the time, you could tell us all a little more about the work you
do at the Selous Reserve, it would be really nice to know more about you all.
:D

Jambo Guides, One day I'd love to visit Selous. May I go back to the very first question on this thread, about not seeing baby baobabs?

This is a standard way of fooling visitors much enjoyed by guides in Limpopo Province, South Africa, and I'm surprised nobody brought up the obvious answer. Which is that a baby baobab doesn't look anything like a big one. Until the tree is about 2 or 3 m tall it will only have juvenile leaves, which are simple (all-in-one-piece); it then develops a few 3-fingered ones and only later develops the normal 5-fingered ones you know so well. Also, at a height of about 2 m the main trunk of a baobab is about the diameter of a pencil -- it only fattens out when it's about 40 years old and up.

And then about flowering times. Yes, what the others said about being visible to pollinators is surely right, but I suspect there's more to it than that. If the plant can set seed before the rainy season, it then stands a chance of ripening and distributing them when there's plenty of food and water for the newly-germinated seedling. But to the best of my limited knowledge, there's been very little work done on these aspects of plant ecology in Africa. Wouldn't it be great if we could find some enthusiasts in Selous do the experiments, and elsewhere to help design them -- this would certainly put Tanzania on the world research map!
