Waptia revisited: Intimations of behaviors
2016, Arthropod Structure and DevelopmentCitation Excerpt :Here I suggest these structures were sensory, providing information to abdominal flexor and extensor circuits, as do segmental mechanoreceptors of the abdomen of the crayfish Pacifastacus leniusculus, thereby controlling abdominal posture (Leise et al., 1987). Tail-flip behavior would imply that associated giant fiber neurons driving this action (see Olson and Krasne, 1981) would have existed for at least 508 million years. Fossils of bent but unruptured Waptia abdomens, which may have tumbled about during burial, show curvature that suggests flexion of as much as 45° from horizontal could have been achieved, enough to provide an escape reaction and certainly enabling escape swimming, as occurs in shrimps today.
