I read something that there is an enzyme akin to ammonia in the flesh of Architeuthis. Not sure about the colossal variety.

Squid are very interesting creatures. There is allot that is not known about them. When I was fishing and camping in Baja we encountered them frequently. One evening a large school of the Humboldt squid came in the cove we were camping at. The noise they made as the water boiled was unforgettable. Many of them beached themselves. The noise they made as they lay there squirting their last bit of water sounded like whales exhaling. It was a very bizarre scene. The beach was littered with their bodies the next day.
