I was reading a bit of J. Scott Turner's The Tinkerer's Accomplice last night that brought up using ammonia for buoyancy in squids (which was great, more popular science books need to discuss comparative buoyancy in Cephalopods) but I was surprised that Loligo was brought up as the ammoniacal squid example; I thought Loligo was non-ammoniacal and negatively buoyant... I can't find a good reference except a paper in a journal I don't have access to; anyone got
Voight J.R., Portner H.O. and R.K. O'Dor 1994. A review of ammonia-mediated buoyancy in squids (Cephalopoda: Teuthoidea). Marine and Freshwater Behaviour and Physiology. 25 : pp.193-203
handy? Or just know the answer and want to tell me?
I had thought that most squids we humans can eat are negatively buoyant and just have to swim a lot (although I seem to remember from Dr. Gilly's TONMOcon I talk that Dosidicus gigas is "seasonally ammoniacal" in that it's inedible from ammonia some times of year but not others.)
