Lobalug

The Lobalug is an aquatic creature found at the bottom of the North Sea. It is a simple creature, ten inches long comprising a rubbery spout and a venom sac. The Lobalug uses its venom sac as a weapon, contracting it and expelling the venom in the direction of an attacker if threatened.

Merpeople use the Lobalug as a weapon, and the venom is used by Wizards as a potion ingredient, though this practise is strictly controlled.
