Tidal pool
During travels, ended up at the seashore, at dawn, at low tide. Being from the desert, it was an utterly foreign environment. There were tidal pools everywhere, and on guard against the incoming tide we gingerly started clambering over rocks to look at the pools.

Suddenly, under a pile of kelp, something started twitching, and slurping, and thrashing about. It looked like it was big, but what could it be? My skin started crawling in fear.

Turned out to be a crab.
