Tatos the Terror Crab

Tatos is the local name, but we know it better as Coconut or Robber Crab (Birgus latro). It is reputed to be able to rip apart a whole coconut with its formidable claws; (they are very strong indeed, and the only way to get them to let go, is to tickle its belly, I'm told).

Its only real enemy here is human; this one was the first I've seen in 12 years on this island, and my first thought was to eat it.
This was brought to me a few days ago, and the next day, another smaller one.

This is a juvenile; its tail has not yet acquired its armour, and its two claws are not yet 'straight'. It betrays its youth, which was spent as a hermit crab, in a shell.



At first I kept them in an improvised cage made from two thicknessess of coiled chicken wire with a closure of a single thickness over each end. Hearing a noise later in the evening, I found the big crab halfway out of a hole it had cut in one end of the cage, so I up-ended the cage, and put a pastry board and a couple of heavy books on top of the hole.

That night at about 1:30am, hearing a scraping noise in one corner of the bedroom, I saw the big crab trying to climb the bedroom wall. I got it off the wall with the help of my large cooking spoon, and it faced me off about a foot away, so I whacked it on the head with my spoon. It ran, with astonishing speed, backwards under my bed. No way was I going to crawl under there in the dark, so it stayed there until 7:30 the next morning, when I'd accumulated enough courage to tackle it. (Or rather, I'd told Ron to pick it up).

An here's Uncle Dick breathlessly explaining the Coconut Crab.
