frog
Aquatic larva, terrestrial juvenile and adult. Tadpole, froglet (small frog with small tail) and adult frog.
Axolotols do not really skip the larva stage. But when they hatch, they are a larva and they do not metamorphose into an adult. They stay that phase all their life.
The free swimming ciliated larva seen in most aquatic mollusks is called a trochophore larva. It has a ring of cilia around its middle that aids in movement and feeding. Trochophore larvae eventually develop into the adult form of the mollusk.
A newt is an aquatic amphibian of the family Salamandridae, although not all aquatic salamanders are considered newts. Newts are classified in the subfamily Pleurodelinaeof the family Salamandridae, and are found in North America, Europe and Asia. Newts metamorphose through three distinct developmental life stages: aquatic larva, terrestrial juvenile (called an eft), and adult. Adult newts have lizard-like bodies and may be either fully aquatic, living permanently in the water, or semi-aquatic, living terrestrially but returning to the water each year to breed.
Tadpole.
Newts like frogs are hatched form transparent eggs laid in fresh water. Newts metamorphose through three distinct developmental life stages: aquatic larva, terrestrial juvenile called an EFT, and adult Newt. Adult newts have lizard-like bodies and may be either fully aquatic, living permanently in the water, or semi-aquatic, living terrestrially but returning to the water each year to breed.
In the case of insects with complete metamorphosis (larva looks very different from the adult (caterpillar/butterfly) and the insect pupates) it's simply called a larva. In the case of incomplete metamorphosis (larva is a small wingless version of the adult, doesn't pupate but molts into final form) it's called a nymph, unless the larval stage is aquatic, like in dragon/damsel/mayflies and others, then it's called a naiad. Aquatic larvae of insects with complete metamorphosis such as mosquitos are still called larvae.
Frog undergoes distinct developmental stages with different cell arrangements. In the tadpole stage, cells are organized differently from adult frogs, with specialized structures like gills. The transformation process involves profound cellular changes during metamorphosis from aquatic larva to terrestrial adult.
There is no such thing as an "adult larva" , a larva is always immature ( a "baby"). If you mean "how is a sponge larva different from and adult sponge?" The answer is: 1. The larva is almost microscopic. You can't really see it with your bare eye. 2. the larva swims around. an Adult sponge stays attached to a surface for its lifetime and can't swim

---- the immature free-living form of most invertebrates and amphibians and fish which at hatching from the egg is fundamentally unlike its parent and must metamorphose
