There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

@Tshokwane

About #78 and #79: why is there this kind of hairs concretion at the end of the front leg/paw ? To mask the claw ? Or because of the ground nature ?

Very impressive photo, a little bit scary (if they were bigger...).

Those are called pedipalps.

They look like little legs and are tactile organs; they feel the ground with them, they manipulate food with them and, for males, those are very important organs, because they use them for sex.

That's why you'll see that males have larger pedipalps; when they're copulating, the male has to be quick because most females are not only bigger than them, but extremely agressive and many times use them for food. So, when he's busy trying not to get killed while they copulate and he says to her ooh lala mon chérie, the male lets out a blob of semen, catches it with a pedipalp and the introduces the semen inside the female's genitalia.

So it's a very, very important organ for a male.

Here, look at the difference between the male's and female's pedipalps.

This is the female

and this is the  male.

@Tshokwane :

1) Thank you very much for yours explanations, great !
I see there isn't only the praying mantis females to eat the males among insects and arachnids !
Does the female kill the male or does the female put the male to sleep in order to give and feed it to the spider childs (as the praying mantis female does) ?
I remember the word "pedipalps" (pédipalpes in french) when I studied the animal biology at the university. But I want to be sure: are these kind of hairs concretions (at the end of the pedipalps) a sort of spoon with which they take a blob of semen in order to introduce it into the female's genitalia ? If yes, I find that fantastic !

2) Let me say:
the male tells "Oh là là MA chérie don't move so much !".
The female answers "Oh là là, MON chéri, you are such a god, I cannot stand still any longer !".

Indeed they are, and they look different according to the species, for Deinopsis it looks just a you described.

Duly noted, Spalea. My french is very much still in the works, but I couldn't resist giving it a try, I'll remember it for next time, thanks!.

Jumping Spider with Boxing Gloves, Amycus sp. (ID by Leonel Martinez) from Ecuador Megadiverso, watch my VIDEO: https://rumble.com/v6ssfj

Its pedipalps end in two bulbs which look like a pair of boxing gloves but are actually the male genitalia.
