Abstract:
ClevBlandj.a ,io!,! is a small estuarine teleost which inhabits the burrows of the Thallassinid crustacean, Callianassa californiensis , presumably to avoid predation and desiccation at low tides. Field observations and laboratory experiments were undertaken to determine the relationship of Clev~landi£ ~ and Callianassa californiensis, whether it be commensalism, mutualism, or parasitism. ~ iDS and ~ californiensis were found to be negatively associated under field and laboratory conditions. In addition, the arrow gobies were found to inhabit the ghost shrimp burrows only during the spring and summer months. Thus, these two species are facultative associates. Many authors believe these species may be evolving toward an obligate commensal rel8tionship~
