Neither cortical nor trabecular: An unusual type of bone in the heavy-load-bearing lower pharyngeal jaw of the black drum (Pogonias cromis)

“…S5). As reported previously, the bony toothplate in the pharyngeal jaws of black drum fish exhibits a unique porous microstructure unlike the common trabecular bones observed in other vertebrates [11] .…”

“…S1E). The black drum replaces its teeth throughout its lifetime [11] , and the immature teeth are embedded beneath the mature ones and within the bony toothplates, as shown in the cross-sectional optical and scanning electron microscopy (SEM) images ( Fig. 2 A,B and Fig.…”

“…In comparison to cartilaginous fish (e.g., sharks, rays, and skates), teleost fish have relatively smaller body sizes/weights. They have evolved a specialized adaption, i.e., the pharyngeal jaws, a "second set" of bony jaws in the throat for durophagous feeding [10,11]. A representative example is the black drum Pogonias cromis (Family Sciaenidae), a molluscivorous teleost that is commonly found in the estuarine and shallow marine waters along the Atlantic coast from New England to Argentina [12].…”

“…A representative example is the black drum Pogonias cromis (Family Sciaenidae), a molluscivorous teleost that is commonly found in the estuarine and shallow marine waters along the Atlantic coast from New England to Argentina [12]. As the secondlargest durophagous teleost fish (second to the Indo-Pacific humphead Maori wrasse Cheilinus undulatus), the black drum fish preys on mollusks and crabs with its powerful pharyngeal jaws and associated musculature [11,13]. The black drum's pharyngeal jaws consist of two separated upper pharyngeal jaws (UPJ) and a massive lower jaw (LPJ), which are located inside the throat of the fish (Fig.…”
