Mantis shrimp/sea mantis are a popular Vietnamese seafood.
Locals call them tôm tít.
There’s not a lot of meat in them but they are a cheap-ish treat, and usually barbecued, steamed, or pan fried in coconut oil.
I don’t recomment the fried version as I find the oil too sweet, and extracting the meat is a hot, messy, oily affair.
But don’t let me stop you – give them a crack …
