Anchor and alternate are swim competition terms. They begin with the letter A.
Leeches are quite fast. They swim fast when they notice vibration in the water so they can attach themselves to a host and feed.
Well, a little. Seahorses has a funny, curled, almost prehensile tail that they can anchor themselves around seaweeds with. And once they have something to hold on to they can lean out from that anchor point. Apart from that they have a really tiny dorsal(=back) fin that they flap at a furious paces to swim about.
Vorticella attach themselves to a substrate with their stalk. They can, however, detach themselves and swim to a different location. They are heterotrophs, so if they are considered plankton, then they are zooplankton.
Lampreys aren´t a class, they´re a separate species. But yes, they are motile, they swim freely - that is, until they attach themselves to a fish host with their mouths and start scraping off flesh with their tongue. But they can let go and swim away whenever they want.
A flight attendant's duties include managing passenger evacuation in the event of an emergency. It's possible that an aircraft may have to land in the sea or on a body of water, so it's essential that flight attendants can swim to be able to assist passengers.

Not all fish swim faster than jellyfish. Seahorses are limited in their swimming capabilities and male angler fish attach themselves to a female and become a parasitic sex organ, never to swim again. Those fish that can outswim a jellyfish can do so because they have a more efficient propulsion strategy, stronger musculature, a more sensitive sensory system and are more streamlined than a jellyfish.
I personally don't think 14 is too old. However, you should be able to swim all four strokes (butterfly, backstroke, breastroke, and freestyle) legally. If you are not very good, I would suggest joining a summer recreational league, not a year-round one.
Most corals have attach themselves to underwater objects and remain there for life. Some corals possess toxins that make them unappetizing to underwater creatures.
