🤔 Guess first

Which one is REALLY true about the Coconut Crab?

The short version

The coconut crab is the largest land-living crab, stretching up to three feet claw to claw. It climbs palm trees, drops coconuts, and tears through the husk with a pinch rivaling a lion's bite force. Though it starts life in the ocean, an adult has lost the ability to swim and will drown in deep water. It can live around 60 years.
