Zephyr Shark (5e Creature)
From D&D Wiki
Medium beast, unaligned
Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 6 (1d8 + 2) piercing damage.
These sharks, altered through magic to adapt to life in the sky, tend to avoid populated areas, instead they make their territory within the close confines of trees, or within the floating debris of wrecked skyships, or among cloudreefs (floating fields of strewn rocks and boulders that hover over the ground). Zephyr sharks are usually fairly placid, attacking only when hungry or provoked.
