The evolution of parental investment in caecilian amphibians: a comparative approach

Abstract: Parental care is widespread among vertebrates and the observed patterns of parental care and investment are extremely diverse. Among amphibians, caecilians (Gymnophiona) exhibit considerable variation in reproductive modes, including both oviparity and viviparity, combined with highly unusual investment strategies (e.g. skinfeeding and intrauterine feeding). In the present study, current knowledge on the reproductive modes is integrated into an analysis of the evolutionary scenario of parental investment of ca… Show more

“…According to Kupfer et al. (), the reproductive modes of only 25% of all known living caecilians are available, and maternal dermatophagy was first reported only very recently (Wilkinson et al., ). Thus, it seems reasonable to expect as yet undiscovered reproductive strategies to exist within the group.…”

“…If copulation and nest construction are added to this period, the complete reproductive cycle of Siphonops annulatus is estimated around 6 months. The small size of the litter and the long‐term brood care define S. annulatus as an amphibian with extremely high reproductive investment, producing high‐quality offspring that, for example, may be able to access a greater variety of prey and be less vulnerable to predation (Kupfer et al., ).…”

“…The modes of parental care are remarkably diverse both within and across animal taxa (Clutton-Brock, 1991;Royle, Smiseth & K€ olliker, 2012). Within amphibians, parental care has been described in all three orders: Anura (frogs: Crump, 1996), Caudata (salamanders: Nussbaum, 1985) and Gymnophiona (caecilians: Kupfer et al, 2016). In particular, a diverse array of pre-and post-hatching parental care behaviours, such as attending, transporting and feeding, have been reported from frogs.…”
