The Atlantic Sea King is a fictional species of fairy that originated from the Spiderwick Chronicles Universe.  They resemble catfish, though it's unspecified if they are descended from them, or if it's an example of convergent evolution.


  • Their canon taxonomy is the "Sirenidae" family, however this would suggest they are salamanders, which they bare no resemblance to.
