Abstract

The morphology of tooth crowns is variable inter‐specifically among caecilians. Cusp number and shape, crown dimensions, and crown curvature characterize various species and have both functional and phylogenetic implications. Ichthyophis, Uraeotyphlus, Hypogeophis, and Geotrypetes have bicuspid teeth; Dermophis, Gymnopis, Caecilia, and Typhlonectes monocuspid. Crown morphology as revealed by scanning electron microscopy is associated with prey grasping and, in one case, possible specialization of prey type.

The presence of spicules (also termed spines, teeth, or denticles) on the intromittent organ, a character unique to male members of some species in the African caecilian family Scolecomorphidae, has long been known (Noble, '31; Taylor, '68; Wake,'72; Nussbaum,'85).

Little is known about the developmental biology of caecilians-tropical, elongate, limbless, mostly fossorial amphibians that are members of the Order Gymnophiona. Ichthyophis kohtaoensis (Family Ichthyophiidae; southeast Asia) is an oviparous species in which maternal care of the clutch is provided.
