What does the pelvic fin do to the fin?
Pelvic fins play a role in stabilization of the body during swimming. The bony fish pelvic fin is simple and is supported on a flat-lying triangular plate, somewhat similar to that of the female of the shark Falcatus. Pelvic fins of all sexually mature male chondrichthyans, however, also feature extensions of the fin axis that form sperm conducting ducts for internal fertilization of females. These paired structures, the claspers, are characteristic of adult male Chondrichthyes.
Chondrichthyans related to the modern chimaeroids also develop a tall dorsal process and a specialized first radial armed with denticles (pre-pelvic tenaculum), as seen in a relatively primitive state in Echinochimaera snyderi.
Do sharks live in the neritic zone?

How does the rainbow trout protect its self?
Salmon have evolved to live in large groups, and this is their primary defence against predators.
Like most fish, when a shoal of salmon feel threatened they will begin to 'school' meaning: move together as a group. Groups of animals who look the same and closely mirror each other's movements make it very difficult for a predator to identify a single target.
Biologists call this phenomena a 'shell game' in reference to the con-trick of hiding a pea under one of three shells, shuffling the shells and having the mark try to guess which shell the pea is under. Herding animals, such as antelope or Zebra, have evolved the same technique.
How animals achieve this effect is still the subject of study, though a comparison is often made with a 'Mexican Wave' where a large crowd coordinate their actions by copying their nearest neighbour.

Frogs do not eat fruit. Frogs are carnivores. They eat insects, snails, etc. Larger frogs may eat other small animals. But they do not do fruit.
How does a fish shape helps it swim trough water?
Well it depends what type of fish.The Whaleshark [which is also the biggest fish in the World] uses its whole body to swim.
with their fins, they can only live in water

I know it's kinda...WEIRD but they/we do.
If you think that's weird listen to this:
A week or so before someone is born they have a full coat of hair all over them. It all falls of and they eat it along with dead skin e.g. and they poop...still in their mom's...
I hope your not eating now...
What is the length of a blue gill fish?
At adulthood, average for this species is around seven to eight inches. Some grow larger, however.
with the black goldfish I believe that the one relative is the celecanth a fossil fish
Plants like the water hyacinth,water lily,arrow head,cabomba,cattail,yellow burhead, hydrilla,elodea,floating moss fern,mosquito fern,water shamrock,are examples of plants that grow in pond water.
Insects like mayfly,damsefly,dragon fly,water scorpion,water stick insect,water boatman,whirligig beetles,great diving beetle larva,dragon fly nymph,mayfly nymph, gnat larva and pupa,are examples of insects that live in pond water.
Also tadpoles, the kind of animal that takes serious websites such as the old Answers.com and trivializes them into what they are now.
Uh, they kinda are turtles, that live in the water, and so they have lungs, which means they have nostrils, which means they stick their head out of the water when they are tired of holding their breath. They get some new air, and they hold their breath and go back under to eat or something until they feel the need to have more oxygen again
btw, that was really dumb question... r u blond or something?
What kind of consumer is a fish?
Okay, so plankton are the producers in the chain, every fish that eats the plankton are primary consumers. Every other fish, such as a shark, that eats the fish that ate the plankton are secondary consumers
