THE AMPHIBIAN TREE OF LIFE
Abstract The evidentiary basis of the currently accepted classification of living amphibians is discussed and shown not to warrant the degree of authority conferred on it by use and tradition. A newExpand

Anuran radiations and the evolution of tadpole morphospace
Anurans (frogs and toads) are unique among land vertebrates in possessing a free-living larval stage that, parallel to adult frogs, diversified into an impressive range of ecomorphs. The tempo andExpand

  • 1 May 2005
The mouthparts of anuran tadpoles are highly derived compared to those of caecilians or salamanders. The suprarostral cartilages support the tadpole's upper beak; the infrarostral cartilages supportExpand

Cranial musculature in the larva of the caecilian, Ichthyophis kohtaoensis (Lissamphibia: Gymnophiona)
Within the Gymnophiona (caecilians) oviparous species with biphasic life‐cycles possess a free living semi‐aquatic larval stage that feeds in aquatic habitats. The larvae pass through a metamorphosisExpand
