Lamprey

The Lamprey is a tier 2 animal.

Mechanics

Worms evolve into lampreys.
- 4,000 XP is required for a worm to evolve into a lamprey.
Lampreys evolve into jellyfish.
- 7,000 XP is required for a lamprey to evolve into a jellyfish.
Lampreys do not drop any meat, but instead yield XP upon being eaten.
As a lamprey, friendly fire is turned off for other lampreys and oarfish: meaning you cannot damage them nor be damaged by them.

Instead of attacking tier 5 animals and above, you will automatically attach yourself to them when dealing damage.
- When attached, you'll receive a portion of whatever food the animal you're attached to eats.
  - This includes food that is normally not part of your diet, such as people or volcano food.
- Attachment does not prevent you from losing oxygen, pressure or damage caused by those.
- Even though you can attach to tier 5 animals and above, friendly fire is still turned on for them and you can be killed by the animal you're trying

The suitable biomes for the lamprey are the ocean, the arctic, and the swamp.
- If a lamprey enters the ocean surface, it will lose oxygen.
- If a lamprey enters the arctic surface, it will lose oxygen.
- If a lamprey enters the deeeep, it will lose pressure.
- If a lamprey enters the swamp surface, it will lose oxygen.

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