They grow things big in the tropics sometimes.
Like this crab.
This pix shows what looks like a hermit crab, using a sea shell for a portable house, in the forest on the dive island of Sipadan. Small enough to cup in your hand.
But this is a baby coconut crab, and he outgrows childish things like protective sea shells…
See that little bit if grey peeking out from behind the shell on the left hand top? That is the end of a 14 cm (5.5″) marker pen lying on the sand.
This fellow is almost a metre across…
And he snacks on coconuts.
