Yes, most fish do have tongues, but they aren’t at all like ours. Most fish have a bony structure called the basihyal on the floor of the mouth that superficially resembles a tongue. But it doesn’t have taste buds, isn’t muscular and has very little range of motion, so it isn’t directly equivalent.
Do fish stick their tongues out?

Can salmon switch sexes?
Nagler of the University of Idaho, “is that these females have been ‘sex-reversed’ and are in fact male.” Such reversals are not unheard of, as salmon sex can be reversed experimentally in the lab, Nagler reports. But these new findings document the phenomenon for the first time in a wild fish population.
Can fishes get pregnant without a male?
Yes, they can. However, the eggs will not hatch into baby fish as they have not been fertilized by a male fish.

Yes, quite a few of them do.
The rapids above the falls are full of oxygen and nutrients, which is a big draw to fish. Although they are built for swimming in turbulent waters, the rapids above the falls do cause a bit of disorientation. Fish will plummet frequently, most of the time without harm.
Why do salmon jump out of the water in the ocean?
The reason, according to a new study, is that they’re infested with sea lice—and are trying to splash them off. Researchers already suspected that salmon leap to dislodge sea lice, a pea-size parasite that feeds on mucus, blood, and skin.
