Spiders are not realy my speciality but I can help on Nos. 2 & 3.

The second photo is actually a whip-scorpion (fearsome looking, but harmless). I am not sure on the species.
No. 3 is a Nephila species (Orb-weaver spiders). It is difficult to say which one, as you have taken a photo of the underside. However, I think it should be Nephila pilipes.

Cheers
Les

Hi Malamala,

Positively identifying spiders is notoriously difficult but here goes:

The first one might be a Wall Crab Spider (Selenops radiatus), found in tropical and sub-tropical regions. Sometimes called "Flatties" because of the extreme flatness of their abdomen which swells when feeding. They are fast moving hunting spiders well adapted to life in caves. They tend to sit still but when they have had enough they dart sideways for cover.

The second one is not a spider but a relation. It is an Amplypygi or more commonly known as a Whip Spider. A Whip Scorpion (Uropygi) are slightly different with tails. Your one is probably of the genus Phrynichus which has 14 species and found throughout the Far East, India, Sri Lanka, the Seychelles and Africa. It is harmless. You can tell the approximate age of the animal by the spines on the raptorial palps. These spines are used for ensnaring prey so when young there are more spines. When older and mature, fighting rivals and mating is more important so they have less spines.

I agree the third is a female Nephila pilipes, the males are much smaller and brown. Harmless to humans though can give a nip.

Hope this helps - Ed
