Did it have spikes/spines on
Did it have spikes/spines on the carapace in beetween it's eyes easiest way to tell between native and Asian paddle crab. Nearly impossible to tell from that photo.

Please advise

Toxic and a danger to our prawn/crab fishery .

Update
So, rang fisheries Sunday and left details with call taker.
Had a call back within 5 minutes to go through more details, sent a picture through. Traded texts to say can't identify it from the photo but would pass on for Monday morning to be followed up.
Monday about 10 have a message on my phone to say they had reviewed the photo and confirmed it was not a paddle crab. Not 100 sure what it was but certain not a paddle crab.
Thanked me for reporting etc. Happy with the follow up and feedback I received. Good job. Message for me is to take more notice, better photo and if I can, catch crab for ID.
