The silkie, or selkie, is a monster from Scots legend, able to shift shape from a seal to a human and back. In Society heraldry, it’s drawn as a seal with a human head. The silkie is erect and guardant by Society default.
No examples of the silkie in period armory are known, and the standard Society depiction is likewise unknown. Pending documentation, the silkie has been disallowed for Society use. For related charges, see mermaid.
