How to Swim Faster - Wakemaker Location
Heat Tolerance - How to Cleanse the Infected Angel Comb
As far as ending up stranded on a mysterious planet goes, you got fairly lucky. How many planets out there are too hot, too cold, have too high of an atmospheric pressure, or an atmosphere consisting of deadly gasses, or no atmosphere at all? Not to mention the gas giants. Instead you’re in a verdant water world, teeming with local floral and fauna, with a breathable atmosphere, and a pleasant enough temperature. It’s not all good news, however - you didn’t evolve as part of this biosphere, and that being the case the native life is inedible to you. Those Nutrient Blocks won’t last you forever, and while starvation won’t kill you as fast as dehydration will, it’s still too often to realistically ignore in the long-term. This page will help you get the Digestion Adaptation in Subnautica 2 so you can consume native flora and fauna.
Page Breakdown¶

Find the Digestion Adaptability Angel Comb¶
Catching fish and harvesting edible Fibrous Pulp is a relatively simple matter - flora and fauna are abundant in the starting biome. Alas, pick any of it up and you’ll get a warning informing you of a “Digestive Incompatibility“. Eat the food anyways and… well, nothing will happen. You’ll just waste whatever it was you tried to eat. Probably not good to imagine what that’s going to look like coming out the other end… In any event, there’s food everywhere, but none of it gives you any nutrition whatsoever. You’re going to have to adapt, just like you did with the high pressure you found yourself threatened by at the start of the game!
To do this you’ll need to find an Angel Comb that can impart the “Digestion” Adaptation to you, and fortunately just such a mysterious plant can be found not far from your Lifepod. Early in the game you’ll get the objective to search for a colonist named Anita, and pursuing this lead will guide you north, north, northeast to this Angel Comb - you can just follow a black cable running along the sea floor to reach it.
It should be obvious that you need to interact with the Angel Comb, which towers over the habitat that Anita was presumably setting up at the base of the Angel Comb, but for some reason both of this guide’s authors missed it and ended up dying of starvation several times before figuring out that we needed to touch the big creepy plant. Still, if we missed it, others might! Don’t be like us - when you reach the camp, interact with the Angel Comb to get the Digestion Adaptation, which will allow you to consume native flora and fauna and recover food and water while doing so!
Where to Find Food¶
Now that you can actually digest the local wildlife, let’s talk about sources of food. Before you had the Digestion Adaptation, you were stuck feasting on processed food, which could be scavenged from the odd sunken crate.
Now that your menu has expanded, you can feast on foods that are easier to come by. In the starting biome, fish are abundant and you can, with a bit of effort, just out-swim and catch them. A single fish can be cooked via a Fabricator and consumed for around 25-30 food each. Should you prefer to go the vegetarian route (or if local stocks don’t support your appetite) you can also use your Survival Multitool to harvest various plants and turn the Fibrous Pulp you get from doing so into an Oily Salad.
Other, more beneficial meals will typically require the use of Salt and Sugar of Saturn, among other ingredients, which are best saved for later when you have more access to these materials in other biomes. If you’re really hungry, you can even recycle Biofuel Blocks into Nutrient Blocks - just add a bit of Salt!
In any event, once you get the Digestion Adaptation, you’re no longer on the calorie clock and can turn your attention to other things… like creating a Scanner and then working towards building your first base.
