- You may be looking for the ship named Mermaid.
Mermen, or mermaids, were a race of aquatic beings that lived in the seas of Earth.
Mermen had a fish's tails from the waist down. Their top half appeared human. They had a second set of inner eyelids. Mermen were unable to breath for long periods on land. (AUDIO: Cryptobiosis), however Magda lived on the surface for over thirty years without issue, albeit in a wheelchair for mobility. (PROSE: Enter Wildthyme)
Amfetriti, one of the two, died. Her daughter Galliteya, the other captive, was looked after by Peri Brown. Nereus led his people aboard the Lankester where they killed De Requin. Galliteya was returned to them. Nereus promised help for the crew who had jumped overboard. (AUDIO: Cryptobiosis)
In the 1980s, Iris Wildthyme and MIAOW stopped Magda the Mermaid from destroying a nuclear power plant and then recruited Magda into MIAOW. (PROSE: Enter Wildthyme) In the Obverse, Magda was the Eighth Doctor's mother. (PROSE: The Blue Angel)
Mermen were also creatures of myth in Earth culture. Mermaids existed in the Land of Fiction, some whom were converted into Cybermen. (AUDIO: Legend of the Cybermen) Albert C. Richardson sarcastically asked if Barbara Wright was a mermaid that had lost her tail. (TV: The Chase) The Eleventh Doctor called an alien doctor who stalked the Fancy a mermaid as she had the appearance of siren. (TV: The Curse of the Black Spot) The Meron, a race native to Gorgol XIII, were also merfolk. (TV: Liberation)
Victorian showmen used to draw the crowds by taking the skull of a cat, glueing it to a fish and calling it a mermaid. The Ninth Doctor compared the Slitheen's Space Pig with this trick while explaining the Space Pig's true nature to Toshiko Sato. (TV: Aliens of London)
Behind the scenes Edit
The Dax featured in the Decide Your Destiny book, The Corinthian Project, were compared to mermen, but given that their story had multiple endings, it's difficult to assert with certainty much about them.
