@mister_monster nice! What manner of beast are they?
@MrNarrow those are blue crabs. They're small for a crab but delicious and ubiquitous along the Atlantic coast of North America.
@mister_monster not the same beast though it seems https://en.wikipedia.org/wiki/Portunus_armatus
@mister_monster yeah I've caught them on the east coast of Australia but it appears they are all over according to that Wikipedia page.
@MrNarrow yeah very different, although they look possibly related beyond both just being crabs. Those are found in Australia and Indonesia right?
