In this work we extend our microichthyological research to emphasize the morphology of jaw teeth, pharyngeal teeth
, gill rakers and their bony cores in flatfishes.
We recorded the presence of fish by identifying scales, otoliths, and pharyngeal teeth
in the sample.
of the Freshwater Drum (Aplodinotus grunniens) a predator of the Zebra Mussel (Dreissena polymorpha).
The passage of food is also enhanced by the disposition of oral and pharyngeal teeth
pecosensis, its forward-facing mouth, raptorial pharyngeal teeth
, and habitat associations suggest it feeds in fluvial habitats (Hubbs, 1941; Hatch et al., 1985; Bestgen and Platania, 1990; Hoagstrom et al., 2008a), most likely on drifting animals entrained within the column or on the surface of water.
These masses are covered with small pointed pharyngeal teeth
that are angled back toward the stomach.
. Teeth on lower pharyngeal element bevelled; most teeth slender, only small number in centre of posterior part of dentigerous area enlarged (Figs 9a, 9b).
So fish that have fewer oral teeth also have fewer pharyngeal teeth
. This shows that on some level there's a genetic control that governs the number of teeth in both regions," said Fraser.
Dorsal fin rays, the vertebrate film and pharyngeal teeth
72 f, g) tentatively assigned upper and lower pharyngeal plates, premaxillae, and isolated pharyngeal teeth
[FIGURE 1 OMITTED] Order Cypriniformes Family Cyprinidae (Minnows) Cyprinidae, genus undetermined ROM 43684, 43685 incomplete pharyngeal arch; 43652, 43686- 43691 pharyngeal teeth
Hence in a visual feeder such as the largemouth bass, gustatory signals affecting the final swallowing of suitable prey may be provided by taste buds co-located with the pharyngeal teeth
that crush and otherwise damage prey organisms prior to swallowing.
