Figure 4. – Borostomias panamensis (Azan). A: Section of a visceral arch showing the numerous vascular cavities (vc) limited by relatively thin bony trabeculae. No embedded osteocytes are seen in the bony tissue (bo). The two arrowheads point to resorbing bone.

Figure 2. – Stomias boa. Tomographic imaging of the right jaw. A: Three-dimensional reconstruction of the external (labial side) anterior part of the jaw, showing a caniniform tooth. The external surface of the tooth is smooth (asterisk). The arrowhead and the arrow point to the unmineralized ligament of the fang and to a small tooth, respectively.
