Identification of tenuis of four French Polynesian Carapini (Carapidae: Teleostei)

2002

Four species of adult Carapini (Carapidae) occur on Polynesian coral reefs: Encheliophis gracilis, Carapus boraborensis, C. homei and C. mourlani. Samples collected in Rangiroa and Moorea allowed us to obtain different tenuis (larvae) during their settlement phases or directly inside their hosts. These were separated into four lots on the basis of a combination of pigmentation, meristic, morphological, dental and otolith (sagittae) features. Comparison of these characters with those of the adults allows, for the first time, taxonomic identification of these tenuis-stage larvae.

“…E. gracilis displays parasitic behaviour, while the three other species are commensal (Strasburg 1961;Trott 1970;Trott and Trott 1972;Parmentier et al 2000). This difference in behaviour is reflected in the buccal and pharyngeal jaw morphology (Parmentier et al , 2000Vandewalle et al 1998).…”

Phylogenetic analysis of the pearlfish tribe Carapini (Pisces: Carapidae)

 AbstractParmentier, E., Castillo, G., Chardon, M. and Pandewalle, P. 2000. Phylogenetic analysis of the pearlfish tribe Carapini (Pisces: Carapidae).-Acta Zoologica (Stockholm) 81 : 293 -306Fishes of the tribe Carapini ( Encheliophis and Carapus ) share a noteworthy peculiarity: they shelter in holothurian echinoderms or bivalve hosts. Some species are considered parasitic, others commensal. This study focuses on the phylogeny of the tribe, using two other Carapidae species as an outgroup ( Snyderidia canina and Onuxodon fowleri ). Insofar as possible, the selected anatomical and behavioural characters where chosen in an ecomorphological perspective, as features that could be responses to various lifestyle-related constraints. Our character selection also took into account the fact that some features are (presumably) linked. Such features were grouped together as a single trait to avoid their overvaluation.This methodology enabled commensals to be separated from parasites, the former belonging to Carapus and the latter to Encheliophis. Carapus species reflect in their morphology the constraints imposed by a diet of hard, mobile, elusive prey, showing predator-type features: a strong dentition, a wide mouth opening, a robust food intake apparatus. On the other hand, the endoparasitic Encheliophis species show a generally weaker buccal apparatus and narrow mouth opening, in relation to the different constraints of their lifestyle where the diet constraints are less pronounced: they eat body parts of their host. Changes in both generic diagnoses are proposed and three species are transferred from Encheliophis to Carapus.
