“…However, this varies in some species as a result of ontogenetic variations. In centrolenids, rudimentary eye pigmentation occurs in early developmental stages (Gosner stages 25–27) but large functional eyes are apparent in older tadpoles [ 39 , 42 , 43 , 50 – 53 ], which is similar to our observations in Micrixalus herrei ( Fig 4A–4F ). As the eyes of M .…”

“…They possess a suite of characters shared with disparate fossorial lineages across the Neobatrachia. One consistent feature, eel-like bodies, is known to be associated with active burrowing into sand and for moving through gravel and vegetation [e.g., 21 – 22 , 38 – 42 ]. Furthermore, this form enables fossorial larvae to enter crevices of various sizes and shapes [ 23 ].…”

“…Muscularized tails with reduced tail fins are also common to M . herrei , Leptobrachella mjobergi [ 23 ], Otophryne pyburni [ 21 ], Nymphargus grandisonae [ 42 ], Espadarana andina [ 39 ], Hyalinobatrachium ibama [ 43 ], Centrolene hesperium [ 38 ], Tetrohyla pulverata [ 40 ], Cardioglossa manengouba [ 41 , 44 ], Staurois tuberlinguis and S . natator [ 45 ], and is assumed to enable locomotion within a sandy substrate [ 46 ].…”

“…Ontogenetic size variation within a specific developmental stage is evident in centrolenids [ 39 , 42 , 51 ] and Micrixalus herrei . For example, in Cochranella granulosa , larger and more active tadpoles were observed in hypoxic environments [ 53 ].…”

Unearthing the Fossorial Tadpoles of the Indian Dancing Frog Family Micrixalidae

Tadpoles of the monotypic Indian dancing frog family Micrixalidae have remained obscure for over 125 years. Here we report the discovery of the elusive tadpoles of Micrixalus herrei from the sand beds of a forested stream in southern Western Ghats, and confirm their identity through DNA barcoding. These actively burrowing tadpoles lead an entirely fossorial life from eggs to late metamorphic stages. We describe their internal and external morphological characters while highlighting the following features: eel-like appearance, extensively muscularized body and tail, reduced tail fins, skin-covered eyes, delayed development of eye pigmentation in early pre-metamorphic stages (Gosner stages 25–29), prominent tubular sinistral spiracle, large transverse processes on vertebrae II and III, ankylosed ribs on transverse processes of vertebra II, notochord terminating before the atlantal cotyle-occipital condyle junction, absence of keratodonts, serrated well-formed jaw sheaths, and extensive calcified endolymphatic sacs reaching sacrum posteriorly. The tadpole gut contains mostly fine sediments and sand. We discuss the eel-like morphology and feeding habits of M. herrei in the context of convergence with other well-known fossorial tadpoles. This discovery builds the knowledge base for further comparative analyses and conservation of Micrixalus, an ancient and endemic lineage of Indian frogs.

“…There are many records of fossorial habits in the literature for centrolenid larvae (e.g. [106, 38, 49, 54, 51, 52]). Altig and Johnston [107] placed centrolenids in the fossorial ecomorphological guild Type I and enumerated a series of characters for that guild: i) LTRF 2/3; ii) a small oral disc; iii) incomplete anterior marginal papillae; iv) very small eye (at least during the first stages but gradually increasing the size); and v) very often, red coloration due to highly vascular skin.…”

The poverty of adult morphology: Bioacoustics, genetics, and internal tadpole morphology reveal a new species of glassfrog (Anura: Centrolenidae: Ikakogi) from the Sierra Nevada de Santa Marta, Colombia

et al. 2019

Ikakogi is a behaviorally and morphologically intriguing genus of glassfrog. Using tadpole morphology, vocalizations, and DNA, a new species is described from the Sierra Nevada de Santa Marta (SNSM), an isolated mountain range in northern Colombia. The new taxon is the second known species of the genus Ikakogi and is morphologically identical to I . tayrona (except for some larval characters) but differs by its genetic distance (14.8% in mitochondrial encoded cytochrome b MT-CYB ; ca. 371 bp) and by the dominant frequency of its advertisement call (2928–3273 Hz in contrast to 2650–2870 Hz in I . tayrona ). They also differ in the number of lateral buccal floor papillae, and the position of the buccal roof arena papillae. Additionally, the new species is differentiated from all other species of Centrolenidae by the following traits: tympanum visible, vomerine teeth absent, humeral spines present in adult males, bones in life white with pale green in epiphyses, minute punctuations present on green skin dorsum, and flanks with lateral row of small, enameled dots that extend from below eye to just posterior to arm insertion. We describe the external and internal larval morphology of the new species and we redescribe the larval morphology of Ikakogi tayrona on the basis of field collected specimens representing several stages of development from early to late metamorphosis. We discuss the relevance of larval morphology for the taxonomy and systematics of Ikakogi and other centrolenid genera. Finally, we document intraspecific larval variation in meristic characters and ontogenetic changes in eye size, coloration, and labial tooth-rows formulas, and compare tadpoles of related species. Ikakogi tayrona has been proposed as the sister taxon of all other Centrolenidae; our observations and new species description offers insights about the ancestral character-states of adults, egg clutches, and larval features in this lineage of frogs.
