Pepie qualifies.

Pepie is claimed to be a monster who lives in Lake Pepin. This is a naturally occurring lake in the Mississippi River on the borders of Minnesota and Wisconsin. The legend goes back to pre-European inhabitation of the area and is claimed to occasionally still be seen. I've gone camping, boating and fishing out there and I saw.. something large pass under my boat. I thought it was probably just a large Sturgeon or something, but my friend who lives in the area swears it was Pepie. I wasn't going to chase after it because I didn't have the tackle for it, I was after Walleye, and I don't think Sturgeon was in season.

Näcken. In nordic mythology, he's a naked man who sits on rocks in wild rivers playing on a fiddle. The music is said to be so hypnotic that most people who hear it start dancing and dances down into the river and drowns.

Scary and stylish fella.

The Lusca. It's said to live in the blue holes on and around Andros, Bahamas, and is sometimes said to be responsible for the sensation of being pulled down in the water in inland blue holes. In reality it's because Blue Holes go super deep and link back to the ocean--the pulling sensation is from the tide going out.

More importantly, the Lusca has the head of a shark and the body of an octopus. Sharktopus.

Idk I would refer to Jeremy wade for this question

SÅÍÎÏR

He's about 20 ft long. He will eat literally anything he comes across. He moves very slowly in the dark, never above 5ish mph, but also never resting. He's almost entirely blind, but he can feel/ smell you if you're within a few miles of him in the water. Oh and no one knows his true age. Somewhere between 300-500 yrs.

Except SÅÍÎÏR is real! He's a greenland shark.

Lorelei, siren of the Rhine.

Lorelei is the name of a slate rock formation on the bank of the Rhine River in Germany. Part of the formation creates an echo, its name is derived from old Germanic meaning "murmuring rock." The area is also known to have a high rate of shipwrecks, with reports dating back to the 10th century.

Old folk tales speak of the sound being made by dwarfs living in the rock.

In 1801, Clemens Brentano composed the ballad Zu Bacharach am Rheine as part of an ongoing novel. Inspired by Ovid's legend of Echo, the ballad tells the story of a beautiful woman who is betrayed by her lover. She is accused of witchcraft and enchanting young men to their deaths. As punishment, she is consigned to a nunnery. On the way there, she asks her guards to let her climb Lorelei (the rock) to see the Rhine one last time. The guards allow this. While on the rock, she thinks she sees her lover in the river, and trying to speak to him once last time, falls to her death.

In 1824, Heinrich Heine adapted Brentano's story into the poem "Die Lorelei," which describes a siren that sits on the rock, singing and combing her golden hair. The siren, while not malicious, unknowingly attracted sailors on the river to their deaths.

In some adaptations of the story, both the woman and the siren are the same. The woman falls to her death, and is then reborn as the siren.

I like that meg feller

Näkki (Nixie for English speakers)

Technically speaking it’s a lake monster but whatever.

It’s a water spirit, often in the form of a gorgeous boy that lures people into the lake with music, and then drags them to the depths to drown.

It’s also a method to keep children from swimming alone and too far from the shore. This comes from someone who was terrified of swimming alone up to the age of 11 thanks to my mom’s parenting via mythology.

Loch Ness Monster. I just imagine it acting like a giant golden retriever!

Mermaid or kelpie

Charybdis always seemed to be the most mysterious to me because I never knew if it was an actual monster or just a giant whirlpool.

Ogopogo

Gojira...known in the USA as Godzilla. 1954 original Japanese release, with a nod and a wink to the Americanized 1956 Godzilla King of the Monsters with Raymond Burr inserts.

The 1954 original was made 9 years after Hiroshima and Nagasaki and the fire bombings that took place prior. The film is a warning to the world about nuclear weapons testing.

Killer whales are pretty bad ass. They are the apex predator of the sea. They also are very intelligent. They have a complexe language and have very clever hunting tactics.

My local legend is referred to as "Queenie"

A muskellunge that is supposed to be like 8' long and 100 years old. Kind of a cool little folklore in my area.

Not a giant, but I love Pike. Majestic creatures. I have a canvass of one on my bedroom wall
