The bishop-fish, a piscine humanoid reported in Poland in the 16th century
Aquatic humanoids appear in legend and fiction. "Water-dwelling people with fully human, fish-tailed or other compound physiques feature in the mythologies and folklore of maritime, lacustrine and riverine societies across the planet.":6
"Ancient sea deities" have been regarded as the "earliest version of a human-fish hybrid". Creatures with a human torso and the tail of a fish appear in the myths of cultures around the world and persist in contemporary popular culture.:6
Piscine humanoids
Water-dwelling humanoids in legend and fiction have frequently been depicted with characteristics of fish.
The Fish-Men are a race of fish-like humans from the Japanese series One Piece. They are modeled after different aquatic lifeforms. The Fish-Men can breed with humans to create half-Fish-Men, half-humans, or Giants to create Wotans.
Hippocampus from Krapopolis is a piscine humanoid. The episode "Prince Hippo" revealed that he is part of a race of Atlantean fish-men with his mother being the unnamed Queen of Atlantis.
The Kanassans are a race of fish-like humanoids from the planet Manassas. They are said to possess psychic abilities, including being able to read minds and see into the future. They featured in the special Dragon Ball Z: Bardock - The Father of Goku
In the Dragon Ball Z series, the alien race of Sūi' (one of Frieza's foot soldiers) is a race of humanoid fish-like aliens who worked in the Galactic Frieza Army
Humanoid-amphibian characters have "been noted across ancient mythologies and, [...] in medieval cryptozoology", as well as fiction of the Western canon and popular culture. The combination invokes notions of humans' animalistic past, and the tension between the two attributes is used to "conceive monstrous and horrifying" and absurd creatures.
Queen Oona from Disenchantment belongs to a race of amphibious humanoids called Salamanders.
Miscellaneous
Some water-dwelling humanoids in fiction and legend have been assigned characteristics of species other than amphibians or fish, or have been presented as "fully human formed aquatic humanoids".

More often, Caliban has been portrayed with fish rather than turtle attributes - scales, fins, and shiny skin - which reflect the critic's or artist's or actor's fixation on offhand epithets rather than the overwhelming evidence of Caliban's essentially human form.
