Regeneration time and morphology of the inhalant siphon of Fonax denticulatus linnaeus, 1758 (Bivalvia, Donacidae) after amputation

To study the process of regeneration and its effect on the morphology of the inhalant siphon of a tellineacean bivalve, Donax denticulatus, individuals were artificially amputated and placed in aquaria under laboratory conditions, in the absence of predators. After amputation, two individuals were s...

After amputation, two individuals were sacrificed twice a day (9 AM and 5 PM) during a 9- day period, and their siphons were examined in the microscope. Within the first 24 hours after amputation, the process was slow, and only the rudiments of the primary tentacles were visible. However, between the second and the third day a fast transformation of the siphon was observed, with regeneration of secondary and tertiary tentacles. The siphon was fully regenerated on the fifth day after amputation. One month later, the siphon showed the same aspect than at the fifth day. Despite the delay observed in the regeneration of the siphon within the first 24 hours after amputation, probably due to physiologic constrains associated with the lack of well developed tentacles, regeneration showed to be a fast process. Development of primary and secondary tentacles must therefore play an important role in providing basic functionality to the siphon, as well as to the whole organism. Fil:Penchaszadeh, P.E.
