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.

Name	Image	Charge Time	Description
Grab		0.35 seconds	Charge boost to grab the target. You can't grab whales, cachalots, whale sharks, humpback whales, basking sharks and hippos. Grabbing a shark causes them to lose their oxygen faster than usual. The duration of the grab tends to shorten as animal's tiers grow. This is noticeable if you compare the duration of a grab with a tier 2 animal (like a crab) and a tier 10 animal (like a thresher shark).

This is a complete list of food that orcas can eat.

Name	Can be eaten by	XP	Description
Barb	All except for the stonefish who spawned it	0	Spawns behind a stonefish using their active ability. Deals damage upon eating it (7% of max life). Poisons anyone who eats it with a base DPS of 10% that lasts 5 seconds (except poison-immune animals). Despawns after 4 seconds.
Bubble	All animals that breathe air	0	Affected by gravity, floats upwards. Spawns out of the window of the shipwreck. Replenishes oxygen to animals that breathe air.
Bird Poop	All except for lamprey and seagull	10	Affected by gravity. Automatically spawns below any seagull every 10 seconds.
Plankton	All	25	Spawns in the ocean.
Ice	All	50	Spawns in the arctic and deeeep.
Volcano Food	All except lamprey	125	Affected by gravity, floats upwards. Spawns out of volcanoes, which can be hidden in and are located in the arctic and the deeeep. When eaten as an animal that is not suited to the arctic, it will replenish some of your temperature.
Meat	All	1000	Spawns where an animal dies (tier 2 to tier 10 animals only). The amount of meat that spawns depends on what animal it was.

Orcas cannot hide anywhere as they are a tier 10 animal.

This section highlights all the changes made to the orca in documented updates so far. A full changelog can be found here.

Update	Changes
December 12th, 2016	Added two new animals with special abilities: whales and orcas!
January 21st, 2017	If a killer whale grabs a shark, it will now lose all of its oxygen.
February 1st, 2017	Killer whales now grab sharks for less time. Killer whales are now slowed down depending on the size of what animal they grab.
February 13th, 2017	Killer whales can now be hit while grabbing. Killer whale's maximum grabbing time for a shark has been reduced from 4 to 3 seconds. Whales and killer whales can now hit each others' species. DogJelly's idea: Whale's attack increases when killer whales or sharks are near. 5% per shark and 15% per orca, stackable 5 times. Attack only increases towards Sharks/Orca.
February 28th, 2017	Sharks and orcas can now eat NPC fish (pollock). Fixed screen being stuck when grabbed by an orca bug. Removed whale damage bonus for sharks (and bonus for orcas is divided by amount of whales near).
March 18th, 2017	Fixed a bug about orcas instantly hitting after release. Orcas now bounce after releasing, to avoid having their victims getting stuck against the floor. Orcas can no longer grab cachalots.
April 5th, 2017 (Beta)	Orcas now only bounce when releasing if their prey is pushed against the ground.
