The Sea Slug (or ADAM Slug) is an underwater creature (a Mollusk) known to naturally produce a raw form of the volatile genetic material known as ADAM. It is apparently indigenous to the sea bed around Rapture, and is utilized in the city to create ADAM, and in turn, Plasmids. The slugs' ability to produce ADAM is the result of a mutation caused by a large Luminescent Biomass in ocean rifts deep below Rapture, which can be seen beneath Persephone in BioShock 2.
In order to produce greater quantities of the ADAM to meet commercial demand for the citizens of Rapture, the slug must go through a symbiotic embedding process, where it is implanted into a small child, specifically, a young girl, aged 5–8 (possibly). Through this procedure, the young girl becomes what is called a "Little Sister", and the slug creates ADAM with the child as its symbiotic host. ADAM is then regurgitated by the Little Sister, which can be processed to make a number of ADAM products for a variety of other uses. In the game, the player can use ADAM from a Little Sister to purchase Plasmids, Gene Tonics, and other improvements at a Gatherer's Garden machine.

Over the course of BioShock, Jack will find Sea Slugs if he chooses to harvest the Little Sisters he encounters. These Sea Slugs, freshly removed from their hosts, are shown to be a brownish-black color, with reddish orange luminescent spots on their exterior.

As in the first game, the slugs are visible during the process of harvesting a Little Sister in BioShock 2, but are only faintly seen. They can also be seen when the player is walking outside in the Atlantic Ocean around Rapture. They are found lying on the sea floor, gripping walls, etc. Subject Delta can pick them up to supply himself with 10 ADAM per slug. There are five in total.
Locations in BioShock 2Edit
Three of them can be found in the beginning underwater section.
- On the left of the main path.
- On a wall near the first left turn.
- In a pipe near the entrance to Siren Alley.
- At the beginning of the level, beneath the wreckage of a collapsed tunnel, near a corpse covered in silt from the floor of the ocean.
- On the top of the staircase near an Alpha Series corpse, in the underwater section on the way to the hidden Plasmid laboratory.
In BioShock 2's downloadable content, Minerva's Den, there are a total of nine sea slugs throughout each level except the last. Some of them are underwater, while others are contained in glass bottles. Each of the slugs in the bottles has a name.
The first four Slugs can be found outside in the ocean starting point.
- On a rock on the right side of the main path.
- On a wall on the right when entering the second area, which contains a broken wall with metal plates all over.
- On the back of a stone pillar with two blue lights when the player falls down a few feet and sees a staircase.
- Go past the above mentioned staircase and wind around until reaching a stone pillar. It is up on the pillar.
The remaining Slugs in this level are located inside the building and are mostly contained in glass bottles.

- Executive Wing: In the Boardroom. It is in a pool of water in front of the giant clock.

- On a big window on the right side after coming out of the Airlock.
- Behind a rock underneath some pink corals.
- Next to a giant steel door opposite a group of pink corals. One can access this location by turning left when seeing a plant with strange, blue polyp-like buds.
- On the top of a rock with an anchor. The player can jump on it from the cliff where the Signal Beacon is located.
The remaining Slugs in this level are located inside the building and are contained in glass bottles.
- Entrance: On the back of the reception desk, which is in front of the player when first entering this level.
- System Programming: In Felix Birnbaum's Office. It is on a shelf directly opposite the door. One can only enter this room by buying a key from a nearby vending machine outside the room.
- Exhaust Venting: Next to the big venting machine. One can find it by turning left and finding the Vacuum Bot.

- On a console on the right side before the entrance to the Maintenance Access Shafts.
BioShock 2 MultiplayerEdit
An exhibit on Sea Slugs can be found at the Oddities Wing of the Point Prometheus museum map of BioShock 2's Multiplayer. Unlike their other appearances through the series, they appear there in various sizes.
Burial at Sea - Episode 1Edit
- Main article: Burial at Sea - Episode 1
In BioShock Infinite's downloadable content, Burial at Sea - Episode 1, three slugs can be seen on a window ledge at the lookout outside the Watched Clock on High Street. A couple observing wonder about how they work.
Burial at Sea - Episode 2Edit
In Burial at Sea - Episode 2, many tested, stuffed and dissected Sea Slugs can be seen at the Fink Manufacturing Research Laboratories. It is revealed that Jeremiah Fink sent people to various points in the Atlantic Ocean for expensive underwater expeditions in order to find the ADAM needed to produce Vigors, as heard in the Voxophone No Profit for the Prophets. A chalkboard also shows their anatomy, while another one reveal that hosts are essential in the life cycle of Sea Slugs, reinforcing their parasitic nature.
Behind the ScenesEdit
- In the early development of BioShock, Sea Slugs were supposed to be found wandering around and gathering ADAM without the need for a host. Little Sisters were later implanted to the game to give the Gatherers an appearance more appealing to players, one which they could pity and eventually spare them.
- All of the sea slugs in Minerva's Den are named after main developers of this downloadable content. (Steve Gaynor, Devin St. Clair, Jeff Fisher, Scott LaGrasta, Mario DiPesa, Rinaldo Tjan, Will Armstrong, Collin Fogel and Brandon Pham)
