Distribution and Habitat
Life History, Abundance, Activity, and Special Behaviors
Until 2016, the tadpoles of the frog family Micrixalidae had not been described. In their study, Senevirathne et al. (2016) provide the first in-depth description of tadpoles from Micrixalidae, a family endemic to the Western Ghats of India and known for their elaborate foot flagging courtship. Females bury their eggs in the sand of streams where tadpoles live a fossorial lifestyle, using their eel-like bodies to maneuver through the substrate. Finding food while buried can be difficult but Micrixalus herrei tadpoles thrive as "sand-eaters" that ingest sand and then feed on organic matter found among the sand grains. Tadpoles of M. herrei have a number of rare morphological traits that show convergence with other fossorial tadpoles known globally. However, M. herrei show distinction from other described fossorial tadpoles by having ankylosed ribs. We do not yet know why M. herrei tadpoles live underground but the authors propose rapid fluctuations of surface water in streams during the pre-and post- monsoon periods of the Western Ghats, extreme within-stream predator pressure, and the abundance of sub-surface food as potential selection pressures (Written by Molly Womack).
