Hand drawn Ink art by William McAusland, writing by Colin Chapman Likely developed for naval special operations, bestial human seals and sea lions are clever, powerful individuals, if lacking in grace and speed on land. They are all but immune to extremes of cold, and while slow on land are incredibly swift swimmers (18m per round), count as aquatic animals when they swim, and can hold their breath underwater or above it for 10 minutes. They have strong, sharp teeth (SV +11/ DMG 1d12+1) and are entirely carnivorous. Although typically playful and curious, pinniped-men can become aggressive when they feel their authority is challenged, and bloody fights are not uncommon among the males in their harems/rafts.
