Biomes

Biomes are regions of the map that contain different forms of food, terrain, and even different animals (by giving afflictions to animals that do not belong in a certain biome) from one another.

King list
The king list is a special leaderboard located in the top left corner of your screen when in-game. It lists the players who have the highest score of any other animal suited to their biome. There is a small icon to the right of each player shown in the leaderboard that represents what their animal is. Being the king of a biome will display a small crown in the colour of the biome (purple for deeeep, blue for ocean, white-ish for arctic and green for swamp) at the side of your name. If you have the highest score of any player on the server the crown will turn gold instead.

Biome afflictions
A biome affliction is a negative effect that is put on animals who stay in a biome for too long when they are not supposed to inhabit it (e.g. if an ocean surface animal stays in the ocean for too long, they will lose oxygen and vice versa). Biome afflictions range from losing oxygen (drowning/suffocating) to losing pressure. The effects biome afflictions have on animals are mostly just taking DPS. Usually the only differences between afflictions are the common times each affliction gives an animal before they start taking damage, and the amount of damage that is dealt every second. An animal can have multiple biome afflictions at the same time.

This is a list of biome afflictions:

Ocean
The largest biome in the game, the borders of its region cover the center of the map.

Animals that are not suited for the ocean will experience the following afflictions:
 * Animals from the ocean surface will lose oxygen in the ocean (though some animals that lose oxygen while in the ocean are still suited to it as they can swim and have long oxygen times).
 * Animals from the arctic will lose temperature in the ocean.
 * Animals from the arctic surface will lose temperature and oxygen in the ocean.
 * Animals from the deeeep will lose pressure in the ocean.
 * Animals from the swamp will lose salinity in the ocean.

 * Glaciers
 * Igloos

Arctic surface food
The arctic surface does not contain any naturally-spawning food except if there's a dead tree that has no leaves, but spawn pink food. Baby penguins can spawn in igloos and can be used as a source of food. Inverted Beaver Dams also spawn here so dam food is also present here. The only other ways any food would appear here is if a player died and they dropped meat or if a seagull flew over and bird poop spawned underneath them. However, the short temperature time a seagull has meant that it would be difficult to find a bird poo here.

Deeeep
The second largest biome, this biome has a border consisting of several small chunks of land outlining the border between it and the ocean. Located at the bottom-left of the center of the map. In addition, you cannot see as far in this biome.

Animals that are not suited for the deeeep will experience the following afflictions:
 * Animals from the ocean will lose pressure in the deeeep.
 * Animals from the ocean surface will lose oxygen and pressure in the deeeep.
 * Animals from the arctic will lose pressure and temperature in the deeeep.
 * Animals from the arctic surface will lose oxygen, temperature, and pressure in the deeeep.
 * Animals from the swamp will lose pressure and salinity in the deeeep.
 * Animals from the swamp surface will lose oxygen, pressure, and salinity in the deeeep.

Apart from that, there are some regions in the abyssal plain in the deeeep that no-one is suited for, such as the extremely salty hypoxic pool and the oceanic rift, where you lose pressure, temperature and salinity, whatever animal you are, In some servers, there are volcanoes that you can enter, and animals who enter will suffer the same too. The game will show everyone can live in there if you enter these places.

Deeeep Swamp
The Deeeep Swamp is a sub biome that is the combination of both the Swamp and the Deeeep, located directly below the swamp. It can be accessed through several underwater tunnels as well as another ground tunnel at the far right of the map. AI controlled Fireflies spawn here.

Deeeep Deeeep Swamp

A TFFA map exclusive, this swamp area is deadly to most animals, with the exception of Ray, Lamprey, Giant Salamander, Giant Softshell Turtle, and Alligator Snapping turtle, and has a part of the map where both ice and plankton spawn, located near ocean deeeep biome swamp border.

Lake
The Lake is a sub biome which is a combination of the arctic and the swamp. Only specific animals live there! Also, arctic animals in the sub biome still lose salinity.

Hypertonic Salty Pool
All animals lose temperature, salinity and pressure here. This place is considered as sea.

Lava
All animals lose temperature, salinity, pressure and floats here. This place is considered as sea.

Volcano Surface
Only exists on big volcanoes on volcanic islands. All animals lose temperature and pressure staying here. This place is considered as air.
