“…The anatomy and micro anatomy of the tongue had been extensively studied in many mammalian species including; rodents (Ciena et al, ; Cizek, Hamouzova, Jekl, Kvapil, & Tichy, ; El Bakary, Emura, EL Bakary, & Emura, ; El Sharaby et al, ; Sadeghinezhad, Tootian, & Javadi, ; Wannaprasert, ), bats (Abumandour & El‐Bakary, ), hedgehogs (Akbari, Babaei, & Hassanzadeh, ), pangolins (Abayomi et al, ), rabbits (Abumandour & El‐Bakary, ), and primates (Burity et al, ). However, further investigations were needed to complement previous investigations and shed more light on the lingual adaptation to different feeding regimes.…”

The current study aimed to describe the anatomical features of the tongues of two micro‐mammals common in the Egyptian fauna; the Nile grass rat (Arvicathis niloticus), and the Egyptian long‐eared hedgehog (Hemiechinus auritus). The tongues of five adult individuals of each species were excised and processed histologically, histochemically, and morphometrically. Statistical analysis comparing the relative tongue length in both species showed that there was a significant difference, which may correlate with the difference in feeding preferences. Grossly, the Nile grass rat has a dorsal lingual prominence with bifurcated apex while, the long‐eared hedgehog has a median slight elevation with rounded apex. Numerous forms of mechanical and gustatory papillae are scattered along the lingual dorsal epithelium. The histochemical detection of keratin by Holland's trichrome stain showed an intense expression in the case of A. niloticus and mild expression in H. auritus. The framework of the tongue (entoglossum) is supported by either a core of cartilage in H. auritus or bone in A. niloticus which incorporated in the lingual root. The lingual glands also showed marked variation, the Nile grass rat exhibit dense populations of mucous‐secreting glands and lesser populations of serous‐secreting glands, the contrary is true in H. auritus. In conclusion, the micro and macro‐anatomical features of the tongues of both species showed adaptive changes to accommodate the feeding lifestyle. Such type of studies using mammals from different phylogenetic traits and almost have different feeding preferences provide answers to many research questions related to tongue evolution among mammalian vertebrates.

The large bamboo rat (Rhizomys sumatrensis) is a fossorial rodent found throughout Indochina that has a distinct habitat dominated by bamboo thickets. In the study reported here, the lingual biology of this rodent is described in detail, based on characteristic features of the tongue and lingual papillae as determined by light and scanning electron microscopy studies. The tongue was found to be elongated with a rounded apex and possessed a median groove and a well-developed intermolar prominence. Three types of the papillae were found on the dorsal lingual surface: filiform, fungiform and vallate papillae. The most abundant papillae were the filiform papillae, the majority of which had a wide base and fork-like processes. Rounded fungiform papillae with one to four taste buds were randomly distributed among the filiform papillae, with a high density found at the anterior tongue, particularly the apex. Two oval vallate papillae were observed on the posterior part of the tongue, surrounded by a circumferential groove into which their numerous gustatory pores opened. The lingual radix had no papillae but contained mucus-secreting Weber's salivary glands. Structural adaptations of the tongue to meet the functional demands of food ingestion and food manipulation in the oral cavity are also discussed.

Comparative tongue anatomy of the rakali (Hydromys chrysogaster) and greater stick-nest rat (Leporillus conditor) (Rodentia; Muridae)

For many mammals, the tongue provides an important functional interface with the environment through roles including manipulating, ingesting, and mechanically processing food items. As such, the adaptations of the tongue reflect different physical properties of an animal’s diet. We sought to investigate whether adaptations of the tongue are apparent in two native Australian rodents that have divergent dietary niches: the semiaquatic and mixed feeding rakali (Hydromys chrysogaster) and the arid dwelling, herbivorous stick-nest rat (Leporillus conditor). Both species retained many lingual features typical of rodents. A notable difference was a large, annular pad surrounding the single circumvallate papilla in H. chrysogaster, suggesting an enhanced gustatory function, which would be consistent with adaptation to a semiaquatic, mixed diet. In contrast, L. conditor appeared to have reduced gustatory sensitivity and mechanical dexterity, consistent with crushing their preferred succulent plant forage and manipulating sticks for nest building. The descriptions provide a novel view of the evolution of soft tissues within Australian endemic rodents.
