From the specialized teeth of Hesperornis and Ichthyornis for catching fish to the unique tomia of parrots, the range of dental structures in birds highlights the incredible adaptability and innovation found in avian evolution.

Aug 22, 2023 · These structures are called tomia or serrations, and they are made of keratin (the same material as feathers and nails) rather than enamel (the hard substance that covers true teeth). Tomia or serrations help some birds grip or tear their food better.

The edges of the rhamphotheca (tomia) are relatively sharp in most species of birds. However, edges are finely serrated for straining small food particles in filter-feeding birds like flamingoes and some waterfowl.

Notched: the bill has a slight nick in the tomia of one or both mandibles. Most frequently the notch occurs near the tip of the upper mandible, as in thrushes (like the American Robin). Conical: the bill has the shape of a cone, as in a White-crowned Sparrow.

Dec 1, 2011 · In many Neornithes, although toothless, serrations of various scales exist on the beak tomia (sharp edges). They generally shape only the outer rhamphothecal surface, but not the underlying bone. The smallest serrations, called scopate tomia, occur in …

The edges of the rhamphotheca are called the tomia, and for the Toco Toucan as for other Toucans as for many other Rhamphastids, are serrated or marked with "Schaugebiss". The beak is used for foraging, feeding, social interaction, prehension of food or of nesting material, and in Psittacines, for locomotion.

Em relação à curiosa boca, os gansos, assim como os flamingos, têm uma língua serrada chamada de "tomia". As aves não possuem dentes, porém, essa estrutura rígida é forte o suficiente para cortar os vegetais e ingerir alimentos escorregadios, como caracóis.
