Biomods are one of the many ways you'll be able to customize your Pioneer Subnautica 2 which will help you better adapt to your environment and not only survive but also thrive. To use them, you'll either need to visit the Bio Lab Station at the Welcome Center or build one yourself at your own base.
There are two types of biomods: active and passive. Active biomods will require an action to trigger them, while passive biomods will be active without manual triggering. You'll automatically have access to two of each when you start the game, and you can choose one for each type; the rest of the Biomods will require you to scan various creatures to unlock them.
All BioMods and how to unlock them
In addition to the two active and two passive biomods you start with, you will have to scan different sea life in Subnautica 2 to unlock new mods. Unfortunately this cannot be done with your traditional scanner either, so you'll have to wait until you can build a mod station at your base and upgrade your scanner to a Bioscanner.
Only one of each type of Biomod can be selected at a timebut you can change them at any time by returning to the Bio Lab Station. However, this may change in the future as the game is still in early access.
Of course, for this you'll also need to find and scan the Modification Station and Bioscanner with your traditional scanner to unlock the recipes for both. in addition once you have the Bioscanner you will need to rescan any desired marine life you have already scanned with a traditional scanner.
You can find one set of scans for the Modification Station and the Bioscanner in one of the Cicada Wreck locations in the Alien Ruinsonce you have the Repair Tool to repair the door. you will naturally being led here when it's time to look for Iso's Blackboxbecause that's where it is, but you can always come here once you have the repair tool.
Most, but not all, of the creatures listed can be found in several locations around the map. The given coordinates are only one confirmed location where you can get the scanbut since you have a link to the image, you can follow these creatures everywhere.

Once through the heated area, you'll cross a large gap of open water to reach the Alien Ruins. The Collector Leviathan guards this gap and swims back and forth.

Scan required: Electric Geordie Location: 1,830 meters directly east of the lifeboat and 345 m deep. They will swim around the edges of the large Heat Pipe in the center of the power plant. You'll know you're in the right place if you're in the middle of what looks like a dome-like structure with an Angel Comb at the bottom.

Chum Cloud Release a cloud of delicious bait to distract predators. |
Scans required: Toxic Sponge, Houndgar Toxic Mushroom Location: 30 meters east of the rescue pod and 12 meters deep. You can find them in several small caves around the lifepod. They're easy to identify because they spew a green toxin that you've probably accidentally swam through a few times before. 
Houndgar Location: 670 meters directly east of the rescue ship and 150 meters deep. This is actually the location of the Tadpole Pens, where you'll find a bunch of Houndgars annoyingly hanging around the entrance.

You may have to accept that you will die instantly after scanning some of themso in that case i would we recommend emptying your consumables inventory before scanning. That way, if you get overprinted, you won't lose much. The scan will remain in your data log as long as you complete the scan before you die.
