I <3 you, blue ring octopus (Hapalochlaena lunulata). I love the fact that, despite being the size of a golfball, you contain enough venom to kill 26 humans. I love the fact that you have the balls to have no known antivenom, that the only known treatment it to immediately start artificial respiration beffore your victim becomes cyanotic, even if your victim appears to be utterly fine and hope for the best. Tetrodoxin. Octopamine. Dopamine. Acetylcholine. Hyaluronidase. Tyramine. Histamine. Tryptamine. 5-hydroxytryptamine. Mmmm.....
I adore you, iruknadji (Carukia barnesi). You're so cute, and tiny, and deadly! Just a-fucking-dorable! Your body is the size of my pinky nail and relatively invisible to the unwary eye, but you've got a meter of pretty pretty tentacles just waiting to sting the shit out of someone. I absolutely love the way you cause hypertension, anxiety and pulmonary edema in severe cases.
Oh, palythoas and zoanthids, how I love thee, let me count the ways..... 1.) You're sooo easy to keep that you're considering among the ideal beginner corals 2.) you're relatively cheap and easy to both harvest and propagate, making you commonly in the retail trade 3.) certain species of you produce palytoxin one of the strongest non-peptide toxins (second only in toxicity to maitotoxin). I mean, who doesn't enjoy a good case of tachycardia, respiratory distress, unstable blood pressure, and the slow destruction of red blood cells?
..... maybe I should specialize in marine toxicology, because I honestly find shit like this morbidly fascinating.
