Extraterrestrial Fauna

Extraterrestrial Fauna

Space is home to many other kinds of animals than those you'd find on Earth. A few animals are hostile and will attack the player, but most are passive. Only a few of them are domesticatable like the livestock on Earth.
Animals you find on other worlds can be divided into two categories: hot and cold. Animals can only survive on planets that either have a similar climate to where they came from, or on temperate planets like Earth.

Space animals do not require an oxygenated environment, but it will make the area count as "temperate" for their survival. For example, if you bring a cold-dwelling animal (like a Sniffer) to a hot planet (like Venus), it will catch on fire, unless it's inside an oxygenated environment.
This makes Earth the ideal place to build a zoo, if you'd like.
You can transport animals between planets using AE2's Spatial Storage system.

The Moon may be pretty barren, but it still has a few animals that call it home.

It's considered a Cold world despite the pretty extreme temperature swings.

Limpet

Birt

Birts are a type of bird? They lay eggs in their nests, are passive unless attacked, and can be eaten. Their eggs can be thrown to stun targets.
