Dental structure and tooth attachment modes in the common fangtooth Anoplogaster cornuta (Valenciennes, 1833) (Actinopterygii; Trachichthyiformes; Anoplogastridae).

Abstract in brief

• The study examined the teeth of the fangtooth fish Anoplogaster cornuta, finding that all teeth are monocuspid, made of orthodentin without enameloid caps, and firmly attached to their supporting bones without evidence of replacement.
• The oral jaw teeth are large, transparent, and ankylosed to bone by a mineralized, largely anosteocytic bone, whereas the pharyngeal teeth have a fibrous, movable attachment that helps in prey transport.
• Smaller teeth on the branchial arches are tightly ankylosed, likely to enhance prey retention in this species' sparse habitat, supporting previous findings on jaw teeth but providing new insights into pharyngeal tooth attachment.]
