Sea Spiders

This is not Halicarcinus ovatus it is more likely Ozius deplanatus but the image quality is very poor but definitely not Halicarcinus ovatus the carapace shape the chelae shape is entirely wrong for that species

Why is this being mapped to sea spiders rather than Brachyura these are Brachyura, sea spiders are something different altogether again they are in the class Pycnogonida, this should be rectified as it is extremely misleading
