Friday Fun: Five Gross and Goofy Body Facts

1. The word arm comes from the Latin term arma, which means “tool.”

2. A sea star’s feet are on the underside of its arms

3. An octopus uses its arms to grab prey and to jet through the water.

4. Lobsters, crabs, and scorpions fight off enemies and grab prey with clawlike pincers on their front limbs. Are those limbs arms or legs? It depends on who you ask.

5. Most dinosaurs walked on four legs, but not T. rex. It had two tiny arms with sharp claws. How did the massive meat eater use its little limbs? Nobody knows. They were strong enough to hold prey but too short to reach T. rex’s mouth.
