There are also shrimps that are not good swimmers, and the big lobster spends most of its time crawling on the sand and rocks on the seabed.

Respiration and circulation: shrimp gills are located on both sides of the dorsal armor formed within the gill chamber, the gill chamber before and after the ventral surface and the outside world. Gills are mostly pinnate, *** 25 pairs, embedded in the chest side wall or the base of the thoracic limbs, the epidermis is very thin, blood flow through the gills when the gas exchange. Inside the gill chamber there is a jaw boat piece constantly oscillating, so that the fresh water flow from the back and the ventral surface into the forward outflow.

The circulatory system is open-tube. The heart is a flat, polygonal, muscular sac located in the pericardial sinus on the dorsal side of the cephalothorax, with four pairs of cardiac orifices, two pairs on the dorsal side, one pair on either side of the posterior end, and one pair on the ventral side of the heart near the posterior end, with valves to control blood flow.
