What are the 3 body systems most affected by amphibian metamorphosis?
In amphibian tadpoles, metamorphosis causes developmental maturation of liver enzymes, hemoglobin, and eye pigments, as well as remodeling of the nervous, digestive, and reproductive systems. Thus, metamorphosis is often a time of dramatic developmental change affecting the whole organism.
What is the most common amphibian?
The three modern orders of amphibians are Anura (the frogs), Urodela (the salamanders), and Apoda (the caecilians). The number of known amphibian species is around 8,000, of which almost 90% are frogs.

They don’t need to further differentiate their body parts. However, after they are born, there is further growth and development of body parts to reach maturity.
What are the 4 stages of metamorphosis?
There are four stages in the metamorphosis of butterflies and moths: egg, larva, pupa and adult.
What are examples of metamorphosis?
Examples of metamorphosis include the tadpole, an aquatic larval stage that transforms into a terrestrial frog (class Amphibia). Starfish and other echinoderms undergo metamorphosis which includes a change from the bilateral symmetry of the larva to the radial symmetry of the adult.
What is the largest type of frog?
Goliath means REALLY BIG! We’re not kidding – the goliath frog is the largest frog in the world. It measures up to 12.5 inches (32 centimeters) long and can weigh up to 7.2 pounds (3.3 kilograms). The goliath frog is as big as some domestic cats!

What hormone is responsible for metamorphosis?
The hormone thyroxine is secreted by the thyroid gland. Thyroxine necessarily participates in the process of tadpole metamorphosis.
What is a group of frogs called?
