---- 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

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.
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.
If a larva is removed from water, it is likely to face severe stress and may quickly begin to dehydrate, depending on the species. Many aquatic larvae rely on water for respiration and moisture, so without it, they may suffocate or die within a short period. The exact outcome will vary based on the larva's species and its ability to tolerate brief periods outside of water. Ultimately, most aquatic larvae will not survive long when removed from their aquatic environment.
Boatsman insects eat aquatic plants, algae, and a few aquatic larva of other species. Backswimmers which look very similar, are predators and have a mean bite.
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.
Aquatic larva, terrestrial juvenile and adult. Tadpole, froglet (small frog with small tail) and adult frog.
the larva is called the Planula
Well, larva is like a baby bug, but there are different types of larva. Like beetle larva, fly larva, etc.
There is no specific term for an aphid larva. It is simply called an "aphid larva".
