Barnacle

Barnacles are stationary animals found in the Commonwealth and on the Island in 2287.

Background
It is unknown which species of barnacle this variant has evolved from, but it is much larger than the smaller crustaceans that can often be found beside it. Barnacles can be encountered in coastal regions of the Commonwealth and the Island. They can be easy to miss due to their dark shell coloration, making them resemble rocks and harder to spot when traversing coastal terrain.

Biology
The barnacle is protected by an extremely hard exterior shell that protects it from predators. Its outer shell has a dark green tint and closer to the mouth is tinted red. These barnacles have developed a unique defense mechanism that causes them to release a small cloud of radiation when it senses danger.

Gameplay attributes
Upon approaching it, the barnacle releases a radioactive cloud that irradiates the Sole Survivor at a rate of +30 rads/s for a few seconds. The player character can activate the barnacle and cause it to release its radiation cloud if it hasn't been triggered yet.

Appearances
Barnacles appear in Fallout 4 and its add-on Far Harbor.

Behind the scenes
The barnacle was designed by Gabrielle Adams and created in ZBrush.
