One hundred million years of skin feeding? Extended parental care in a Neotropical caecilian (Amphibia: Gymnophiona).
Maternal dermatophagy, the eating of maternal skin by offspring, is an unusual form of parental investment involving co-evolved specializations of both maternal skin and offspring dentition, which has been recently discovered in an African caecilian amphibian. Here we report the discovery of this form of parental care in a second, distantly related Neotropical species Siphonops annulatus, where...
متن کاملA New Species of Skin-Feeding Caecilian and the First Report of Reproductive Mode in Microcaecilia (Amphibia: Gymnophiona: Siphonopidae)
A new species of siphonopid caecilian, Microcaecilia dermatophagasp. nov., is described based on nine specimens from French Guiana. The new species is the first new caecilian to be described from French Guiana for more than 150 years. It differs from all other Microcaecilia in having fewer secondary annular grooves and/or in lacking a transverse groove on the dorsum of the first collar. Observa...
متن کاملAutomated mapping of social networks in wild birds
What is interesting about these amphibians? Caecilians may be most interesting by virtue of their phylogenetic relationships. As their sister group, they are equally as important as Batrachia (all the frogs and salamanders put together) to any attempt to infer features of their common amphibian ancestors and the history of early terrestrial vertebrate life. For example, that all oviparous caeci...
متن کاملIdentification and localization of neurohypophysial peptides in the brain of a caecilian amphibian, Typhlonectes natans (Amphibia: Gymnophiona).
The amphibian order Gymnophiona contains more than 150 different species of caecilians. The characterization and distribution of neurohypophysial peptides, however, has not been described for any member of this order. By using high-performance liquid chromatography, radioimmunoassay, and mass spectrometry, we identified the peptide arginine vasotocin (AVT) in brain and pituitary extracts from t...
متن کاملEffect of skin application of sun-flower oil on serum triglyceride and cholesterol in premature newborns
Introduction: Total parental nutrition is essential in premature newborns who are unable to have oral feeding. Intra venous Lipid (Intra lipid) is used to preparing essential fatty acids and a compact source of energy. We aimed in this study to investigate the effect of skin intra lipid. Methods: Premature newborns, who were through admitted in NICU unable to feed orally, were investigated in...
