Subnautica 2 Creature Eggs: All Egg Locations and Hatching Guide

Creature Eggs and Alien Containment Overview

Creature eggs are a fascinating collectible and gameplay system in Subnautica 2. Scattered throughout the ocean, often tucked in nests or hidden in caves, these eggs can be collected and hatched in an alien containment tank. Hatching creatures lets you study them, farm them for resources, or simply keep them as exotic pets. It also fills out your database with full life-cycle entries for each species.

To hatch eggs, you need an alien containment tank, a large glass cylinder module built inside a multipurpose room. The containment tank requires power and must be placed on the ground floor of a room. Once built, you place eggs inside and wait for them to hatch, which takes a varying amount of time depending on the species.

Eggs are species-specific. Each creature type lays a distinct egg with a unique appearance, and the hatched creature behaves like its wild counterpart but is contained. Some eggs are easy to find in the shallows, while others are deep in dangerous biomes or hidden in predator nests, making egg collection a long-term collection quest that spans the whole map.

• Each species has a unique egg.
• Rare eggs are hidden in dangerous biomes.

Finding and Collecting Eggs

Finding creature eggs requires exploration and a sharp eye. Eggs are usually found in or near the habitats of their parent species. For example, gasopod eggs appear near gasopod herds in the kelp forests, while boneshark eggs are found in deep bone fields. The eggs often rest in small nests on the seafloor or tucked against rocks, glowing faintly to distinguish them from ordinary rocks.

Collecting an egg is as simple as picking it up, but the danger lies in reaching the location. Many eggs are guarded by their parents, who become aggressive if you approach the nest. Others are in caves or deep zones full of predators. Always clear the area or use stealth, grab the egg quickly, and retreat. Some of the rarest eggs, like leviathan eggs, are in extreme-depth locations that require a Prawn Suit.

Use the scanner to confirm an egg before you grab it, because some objects that look like eggs are actually creatures or hazards. Once collected, eggs go into your inventory and can be stored in lockers until you have a containment tank ready. Label your storage so you know which egg is which, because some look similar.

Hatching and Raising Creatures

Once you have an egg in your alien containment tank, hatching is a matter of time. Different species hatch at different rates, ranging from a few minutes for small fish to considerably longer for large predators. During this time, keep your base powered, because a power outage can pause or reset the hatching process. You can watch the egg develop, and a notification appears when the creature hatches.

Hatched creatures live in the containment tank and can be observed, scanned for full database entries, or harvested for resources. Some creatures, like bladder fish, can be a sustainable food and water source if you breed them. Larger creatures need more space, and overcrowding the tank causes problems, so build additional containment units if you want a large collection.

You can breed creatures by placing two of the same species in a tank. Over time they produce eggs, which hatch into more of that species, creating a self-sustaining population. This is the basis of creature farming: breed useful species for resources, food, or research. Just be aware that some creatures are aggressive even in containment, so do not enter a tank with hostile species inside.

For plant life, you can add flora to the containment tank to create a complete ecosystem. Some creatures eat certain plants, so a planted tank can sustain herbivores without manual feeding. This creates a beautiful, living exhibit in your base and adds a relaxing element to the survival gameplay.

Egg Collecting Tips and Rare Finds

Egg collecting becomes a rewarding side quest as you explore the deeper biomes. Start with easy eggs in the shallows to practice, then gradually seek out rarer species. Keep a dedicated storage locker for eggs, sorted by biome, so you can track your collection progress. The database tracks which species you have hatched, giving you a completion checklist to work through.

Rare eggs are the most exciting finds. Leviathan eggs, if the species lays them, are prized trophies that require deep expeditions and top-tier gear to reach. Crabsquid and crabsnake eggs are found in their respective caves and are dangerous to collect due to the parent creatures. Some eggs may only appear under specific conditions, such as at night or in a particular season, so revisit biomes at different times.

Building a dedicated egg-research base is a great late-game project. A large room with multiple alien containment tanks, each housing a different species, becomes a living museum of the planet's fauna. Add growbeds with bioluminescent plants for ambiance, and you have a beautiful and functional base module that showcases your exploration achievements.

• Start with shallow eggs to practice collecting.
• Keep a sorted storage locker for eggs.
• Rare eggs need deep expeditions and top gear.
• Build a dedicated containment research base.
