Shrimp creeper's body is flat, about 15 cm long and 2 ~ 4 cm wide. It has a pair of mantis-like broadsword legs on its chest, and the hard shell on its back is evenly divided into 10 knots. The whole shrimp is covered with soft, hard, long and short bristles and strange legs, which are densely packed. When swimming, those bristles are constantly flapping, and the tail is like a small dustpan.
