In the top right is a rough sketch of an intelligent zero g crustacean.
At the bottom is a size comparison sketch of a six foot tall human and a /male and /female Burrabb. I haven’t altered the Burrabb body design much since I drew this sketch back in 1999. Most of the changes have been to the design of the head. The Burrabb are a two sexed species with one sex being substantially larger than the other. The Burrabb sexes don’t directly translate to human male and human female. The breeding process is rather different than ours. The social structure resembles what might develop if lions became civilized, a society in which group marriages are the biological norm. It’s not polygamy if everybody does it.
