The Icealos hand has thinner bones and a extra joint.
The bones and fingers are thinner because before they developed technology (like before we did) they used these thin fingers to pry bark and rocks. They could work them into crevices and use their strength to pull whatever it was apart.
The claws are very hard, and very sharp. Capable of gouging steel.
The 4 fingers have 4 joints and the thumb has 3.
The nails are rather long, but they have adapted to them. They are capable of everything that we are.
The extra joint evolved to give a Icealos a firmer, more solid grip on a branch or the like while climbing.
The J. stands for joint.
I put a line around the bones where there flesh would be so you could get a idea how big their fingers are.
Icealos species belongs to me.
