3rd Instar!

4 scorplings have molted into 3rd instars. These are the skins. They're just about 2cm long.

Here's a closeup of one. It probably just finished molting a few hours ago. The telson(venom bulb) is still white but will turn a yellowish-brown later. The four eyes (2 near the mouth, the other 2 are quite close together so it looks like there is only one eye) can be seen very clearly. The armour/exoskeleton will also turn dark green/black later.

edit: the 2 eyes near the mouth are the lateral eyes. The other two are the two median eyes.
