Orca

The Orca (rarely referred to as Killer Whale) is a tier 10 animal.

Mechanics

 * Dolphins evolve into orcas.
 * 48,000 XP is required for a dolphin to evolve into an orca.
 * Orcas do not evolve into any other animals, as they are one of the latest animals.
 * Orcas drop meat upon death.
 * As a tier 10, friendly fire is turned off for all tier 1 animals: meaning you cannot damage them nor be damaged by them.

Suitable Biomes

 * The suitable biomes for the orca are the ocean and the arctic
 * If an orca enters the ocean, it will lose oxygen; however it can swim and its oxygen time is long enough for this to not matter.
 * If an orca enters the arctic, it will lose oxygen; however it can swim and its oxygen time is long enough for this to not matter.
 * If an orca enters the deeeep, it will lose oxygen and pressure.
 * If an orca enters the swamp, it will lose oxygen and salinity.
 * If an orca enters the swamp surface, it will not regenerate salinity.
 * The suitable biomes for the False Killer Whale (a stat-changing skin of the animal) are the ocean and the deeeep, allowing the Orca to be immune to pressure in the deeeep at the cost of loosing temperature in cold biomes.
