False.
The photo is likely real: Apparently pork rectums are a delicacy in some parts of the world. And supposedly they have a consistency similar to calamari. But the notion that they could be swapped for calamari is hypothetical: the FDA responded to the hype by stating that there has never been a single case discovered of pork rectums being sold as calamari. And probably for good reason: they are pungent to prepare, and they have an external market demand.

You know what is delicious, though my friends think I am crazy, it is “Pho Noodle Soup with Tripe” (Tripe being cow stomach cut intot little strips) it reminds me a calimari for some reason and the Vietnamese Soup base witht he noodles and fresh basil and bean sprouts is just deliciouso!
