All larvae of Ichthyopsida show a great similarity in many important traits. The amphibian larvae, however, have a considerable number of characteristics, which can be considered as comparatively new caenogenetic adaptations. They are most numerous in larvae of Anura. In many fishes having a larval stage in development there is also a metamorphosis more or less similar to the amphibian one. The influence of the thyroid on fish metamorphosis is very variable and never so pronounced as in… 

Developmental Changes in the Orientation of the Anuran Jaw Suspension

Many major taxa have evolved complex life cycles with distinct larval and adult forms separated by a rapid transformation, or metamorphosis. Holometabolous insects and anurans are perhaps the best

The phylogeny of amphibian metamorphosis.

Evidence that metamorphic changes in frogs arose as further modifications of changes unique to lissamphibians is provided, as well as a new method by which such questions can be examined.

Live‐bearing has evolved in all three orders of amphibians—frogs, salamanders, and caecilians. Developing young may be either yolk dependent, or maternal nutrients may be supplied after yolk is

A way for regenerative medicine to induce limb regeneration in humans is to develop medical procedures to recreate soft blastemas that can grow, a long and difficult process because it counteracts mammalian evolution toward scarring.

The Effects of Snake Predation on Metamorphosis of Western Toads, Bufo boreas (Amphibia, Bufonidae)

For some anuran species, synchronous metamorphosis may function as an antipredator adaptation by swamping predators during the period of transformation. We examined the levels of synchrony of


It was found that until the eruption of the forelimbs, the larger a tadpole is, the longer it can maintain its position in a steady current and the length of the tail appears to be a positive factor in sustained swimming.




Many morphological characters previously considered to separate the Urodela from the Anura are now found not to apply to these primitive genera and their anatomical relationships lend no support to the opinions advanced.

The Roles of Motile Larvae and Fixed Adults in the Origin of the Vertebrates

The present writer continued to conduct a yearly review of the problem of the origin of the vertebrates, gradually arriving at the conclusions recorded in this paper and more fully in his forthcoming book, Evolution Emerging (1948).

The Development of Eleutherodactylus portoricensis

The name Eleutherodactylus portoricensis was proposed by Schmidt (1927) after an extensive survey of the confusion of Puerto Rican species with the Lesser Antillean martinicensis; it is evident that much remains to be done to establish the specific developmental characteristics of true Martinicensis and the Jamaican species.

Die Ontogenese der Vögel als Evolutionsproblem

The comparative study allows us to trace the progressive evolution of such a system in avian phylogeny by ascribing to the evolutional stages the successive appearance of transitional particularities which characterise the egg and the ontogeny of birds.

Effects of thiourea and phenylthiourea upon the development of Eleutherodactylus ricordii.

It was found that eggs immersed in water will develop normally and at the usual rate providing the jelly layers and vitelline membranes are removed, and developing eggs were raised in solutions of thyroid-inhibiting drugs.

The Occurrence of Increased Activity of the Thyroid Gland in Rainbow Trout at the Time of Transformation from Parr to Silvery Smolt

It is concluded that male rats living in a sheltered environment in Baltimore, Maryland, are fertile throughout the year, and seasonal changes in reproductive rates apparently depend upon the female.

Comparative Physiology of the Thyroid Hormone

The striking effects of thyroxin on vertebrates have given rise to the question whether this compound has any effect on lower forms, and this review will include a summary of the work done on Invertebrates and Tunicates.

Order of Appearance of Scales in Speckled Trout

In Salvelinus fontinalis two scale papillae develop on the lateral line over each myotome, and chief variations are bifurcation of rows and extension of rows posteriorly.
