From publisher blurb:
Introduce some water-based bad guys in your Savage Worlds game by including the swimming creatures in Monster Brief: Aquatic. In this product you will find:
The clockwork fish is an (often dwarven) construct that can be used to guard watery treasures and the like. Includes a swarm "school" version.
The electric fish is an aggressive predator that zaps its prey, potentially stunning or killing it. Includes a swarm "school" version.
The scutlid is a spell-wielding, greedy treasure-seeker who is not above sinking merchant vessels to acquire their wealth.
The zin-kan is one of the seas' most dangerous (and biggest) predators. Aside from its tentacles and many mouths, it can emit a powerful water blast capable of creating ship-swallowing whirlpools.
