I was surprised that most people guessed over $10,000.* If you had asked me, I could not think of any invertebrate that could command that sort of price tag.
I polled because I had read about this crayfish, named “Chao Khun Chang.” It’s an unusual colour morph, but otherwise, it is the ubiquitous Louisiana red swamp crayfish, Procambarus clarkii.
As far as I know, it was sold for the highest price ever paid for a crayfish, and possibly for an invertebrate:
It sold for 1 million baht in Thailand, which is in the neighbourhood of US$28,500.
By way of comparison, I’ve been examining the price of crayfish in the North American pet trade for several years now (Faulkes 2013, 2015). The average sale price is $5 to $25 (depending on species). The highest asking price I’ve ever seen for a crayfish was $80, and the highest price paid (including shipping) was $65 (Faulkes 2015).
This crayfish is the invert arowana. It’s amazing.
