Biomods are one of the many ways you will be able to modify your Pioneer Subnautica 2 to help you better adapt to the environment and not just survive, but thrive. To apply them, you must either visit the Bio Lab Station at the Welcome Center location or build one yourself at your own base.
There are two types of biomods: active and passive. Active Biomods will require actions to trigger them, while Passive Biomods will be active without a manual trigger. When you start the game, you automatically have access to two of each and can choose one per 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 bio mods you start with, you have to scan different marine life in Subnautica 2 to unlock new mods. Unfortunately this cannot be done with your traditional scanner either, so you have to wait until you can build a modification station at your base and upgrade your scanner to the bioscanner.
Only one of each type of Biomod can be selected at a timebut you can change them at any time by going back to a Bio Lab Station. However, this may change in the future, as the game is still in Early Access.
Of course, to do this, you'll also need to find and scan a Modification Station and a Bioscanner with your traditional Scanner to unlock the recipes for both. In addition, once you have the bioscanner you need to rescan any marine life you may have already scanned with the traditional scanner.
You can find a set of scans for both the Modification Station and the Bioscanner at one of the Cicada Wreck locations in the Alien Ruinswhen you have the repair tool to fix the door. You will do it naturally lead here when it's time to look for Isos Blackboxbecause this is where it is, but you can come here anytime you have the repair tool.
Most of the creatures listed, but not all, can be found in multiple locations around the map. The coordinates given are only a confirmed location where you can get the scanbut since you have a picture reference, you can keep an eye out for these creatures everywhere.

Scans required: Toxic Sponge, Houndgar Toxic Sponge Location: 30 meters east of the lifepod and 12m deep. You can find these in several of the small caves around the life tube. They're easy to spot because they spray a green toxin that you've probably accidentally swum through several times by now. 
Houndgar Location: 670 meters directly east of the lifepod and 150m deep. This is actually the location of the tadpole pens, where you'll find lots of Houndgar annoyingly hanging around the entrance.
