16: I saw this one on the floor of the bathroom just before offloading some liquid cargo. This was the ideal time to spot it, because otherwise I'd've been rooted in place for I-don't-know-how-long while I finished my business, which would've been potentially disastrous. As it was, I was able to smash it in some toilet paper and deposit it in the bowl before giving it a burial at sea. It was about a nickel's diameter and halfway between scarily compact and spindly-looking; considering the previous spider, I wasn't in a take-chances mood. When am I ever?
