Starfish encounters: An experimental study of its advantages

  • N. A. Sloan
Specialia

Summary

The predatory starfishCrossaster papposus exploits a chemically mediated escape response in another predatory starfishAsteria rubens when a common food resource is available to both species. Intraspecific avoidance amongC. papposus is strong and functions in dispersal. Responses to inter- and intraspecific encounters among starfish may be important to the predatory ecology of species in high positions in their food webs.
