Creature Type

Source Interstellar Species pg. 43
Choosing a creature type is largely thematic, rather than mechanical. Many creature types include additional abilities like darkvision, specific immunities, or other abilities appropriate for NPCs designed using Alien Archive, yet you shouldn’t apply these abilities to your species automatically. Instead, consider them as inspiration. The creature type might inform your species’ abilities, physiology, and culture, or you might choose a creature type that best fits traits you’ve already chosen. You can also roll on Table 2-5: Creature Type on page 46 if you want to select randomly.
If your creature is aquatic, you can give it the water breathing universal creature rule. If you do, you can also give it the amphibious universal creature rule.
