Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail", usually hidden entirely under the thorax. These ocean critters predate the dinosaurs! [7] Like the two other species in the same family, the gonophores of females are exposed. Instead, they have what’s called amebocytes, which are feisty little cells that attack pathogens (the bad guys in the cellular world, which cause disease) by trapping them in what’s basically a wall of goo.

They are often seen in watering troughs. It is widely caught for food. In J. L. Munro. They are found in water or wet areas, such as in or alongside streams or puddles but they can occur in cisterns, livestock watering troughs or most open outdoor container with water. Often, horsehair worms occur in seemingly inextricable tangles of two or more individuals, especially during the breeding season, which is generally in the springtime.
