Jellyfish

The Jellyfish is a tier 3 animal.

Mechanics

 * Lampreys, crayfish, Climbing Cavefish, crabs, and king crabs evolve into jellyfish.
 * 7,000 XP is required for any of those animals to evolve into the jellyfish.
 * Jellyfish evolve into squid, catfish, axolotl, giant isopod and little auks.
 * 0 XP is required for a jellyfish to evolve into a squid.
 * Jellyfish drop meat upon death.
 * As a jellyfish, friendly fire is turned off for other jellyfish and whales: meaning you cannot damage them nor be damaged by them.

Passive Abilities

 * You poison anyone who makes contact with you (except for animals that are immune to poison or have friendly fire turned off for you).
 * However, you can poison whales when they absorb you.
 * You are immune to poison.
 * You move sporadically. Hitting opponents when bursting to deal higher damage.

Suitable Biomes

 * The jellyfish is suited to every biome (at least in FFA), apart from those where no-one else can survive (such as the extremely salty pool and the oceanic rift, both in the deeeep abyssal plain, where they'll lose salinity, temperature and pressure). Before, it wasn't suited for the swamp and swamp surface.
