It grew to a length of 6.65 cm (3 in), and had a large bivalved carapace and a segmented body terminating into a pair of tail flaps. It was an active swimmer and likely a predator of soft-bodied prey. It is also one of the oldest animals with direct evidence of brood care.One Small Step for Arthropods. ... They had a long, sharp, spinelike tail—hence the name "sea scorpion"—but there is no indication that they could sting. They did have large spiny legs for grasping prey, and some had pincerlike claws. So these were probably the first predators that could efficiently feed on the hard-shelled trilobites ...Question marks indicate uncertainties regarding independent or common origin. Phototaxis is a kind of taxis, or locomotory movement, that occurs when a whole moves towards or away from a stimulus of light.

Jointed, segmented ventral appendages are the hallmark of arthropods, and they are thought to be a key innovation that has helped fuel the tremendous evolutionary success of this clade (Adamowicz etal. 2008).These arthropodized appendages have diversified in both form and function, contributing to core organismal activities including reproduction, feeding, sensation, locomotion ...Subphylum Hexapoda. The name Hexapoda denotes the presence of six legs (three pairs) in these animals as differentiated from the number of pairs present in other arthropods. Hexapods are characterized by the presence of a head, thorax, and abdomen, constituting three tagma. The thorax bears the wings as well as six legs in three pairs.ological body segment, like other arthropods.
