Crystalite Elements

Crystalites are typically considered to have one or two permanent elements, which are based on the natures of their original biome and their animal and plant inspirations. Exactly what the elements are called, and how finely they may be subtyped, varies across cultures.
In general, there are four basic categories that elemental subtypes can be divided into:

Water // Liquid

frequent subtypes include Freshwater, Saltwater, and Ice

Land // Solid

frequent subtypes include Earth and Flora (which can be further broken down into Wood, Foliage, Flower)

Wind // Gas

Light // Ray

frequent subtypes include Fire and Lightning

unlike the other primary types, this category includes subtypes that are characterized by a lack of light: Shadow and Moon

Animal Elements

Common Elements

Water

aquatic creatures, freshwater fish, amphibians, waterfowl, wetlands animals

Sea

whales, sharks, saltwater fish, seabirds, crustaceans

Land

most creatures that live among forests or mountains but not in trees or in caves, flightless birds

Earth

burrowing creatures (rabbits), animals that den underground (foxes)

Sky

flying creatures

Wind

land-bound creatures that live in open areas (lions) or travel extensively (horses) or run very fast (cheetahs)

Fire

tropical or desert-dwelling animals or birds, poisonous or venomous creatures

Niche Elements

Ice

polar creatures

Lightning

electric eels, fireflies, bioluminescent creatures

Moon

strictly nocturnal creatures

Shadow (usually but not always fel)

if not fel, then wholly underground or cavebound creatures

Wood (woody plantlife, trees) *

arboreal animals

Foliage (green plantlife) *

some insects (aphids, stick bugs)

Flower (including fruit and mushrooms) *

specialized creatures like fruit bats and hummingbirds

* Usually used when a plant is a visible part of a crystalite; rarely indicates the animal portion.
