Contributions to the Biology of Carapid Fishes (Paracanthopterygii: Gadiformes).
Parmentier and Vandewalle (2005) found that the time required for carapids to die when exposed to holothuroid saponins is 2 to 16 times longer than for other fishes and suggested that the resistance of pearlfishes to holothuroid toxins may be related to specializations of the gills.
Twelve fish species, including 5 carapids and 7 species of free-living fishes, were used in the analyses.
The carapids were collected by scuba diving (3-15-m depth), along with their holothuroid hosts (Bohadschia argus Jaeger, 1833, Bohadschia atra Massin, Rasolofonirina, Conand & Samyn, 1999, Thelenota ananas (Jaeger, 1833), or Holothuria forskali Delle Chiaje 1823).
Comparisons were made between (i) each species of fish, (ii) free-living fishes and carapids, and (iii) Mediterranean and tropical species.
The gill morphology of the five species of carapids (C.
The opercular frequencies of the carapids were much lower than those recorded for free-living fishes (21 to 70 OM/min) with the lowest in Carapus acus and the highest in Encheliophis gracilis (Table 1).
The red blood cells of the carapids did not appear to be affected by exposure to saponins (Figs.
It has also been demonstrated that carapids are much less sensitive to Cuvierian tubules as they die later than free-living fishes, and they do not seem to be harmed by the saponins of the holothuroid integument.
