The Lamprey is one of the Creatures in the Aberration-DLC of ARK: Survival Evolved.

Basic Info[edit | edit source]

Dossier[edit | edit source]

This section is intended to be an exact copy of what the survivor Helena Walker, the author of the dossiers, has written. There may be some discrepancies between this text and the in-game creature.


Xenomyzon luminosus is one of the most poisonous aquatic species I've ever encountered. While its trademark glowing tail makes it easy to spot and identify, those luminescent glands are also where it products and stores a debilitating poison.

Xenomyzon has developed a particular fondness for blood, and whenever possible, it will attempt to latch onto human subjects. Once it does, it injects a poison for which there are only two cures: A specialized antidote or time. I would not recommend the latter.


While Xenomyzon cannot be brought to heel, some survivors have stored them in fish baskets for other uses. This keeps the subject alive and contained, but not properly tamed.

~ Helena

Behavior[edit | edit source]

Lamprey lurk wriggling in the water, waiting for survivors or tames to pass by, whereupon they leap gleefully and attach themselves to their victim. They pursue their victims onto land. Once attached they apply the Charged Light buff, the Mega Rabies debuff, which slowly damages the player, and the Lamprey Poison debuff, which very slowly reduces health. The duration of the debuffs is dependant on the Lamprey's level.

When attached, the Lamprey can be seen sucking away at the bottom right of the screen; it doesn't drastically obscure the player's vision like a Leech. It can be removed by standing in a campfire, just like a Leech.

Appearance[edit | edit source]

Lamprey look similar to eels, with a scaleless, elongated grey body. However the tip of their tail glows with Charged Light, a thin glowing purple stripe runs down side of the front part of the body, and they have small glowing orange fins down the rear of the bodies.

Color Scheme and Regions[edit | edit source]

X mark.svg

The Lamprey always spawns with the same color scheme and has no color regions.

This means it is currently impossible to make alterations to the Lamprey's colors.

Combat[edit | edit source]

This section describes how to fight against the Lamprey.

General[edit | edit source]

Mildly annoying water-based parasite. Any strategies used against leeches should help here

Strategy[edit | edit source]

Use a pike or ranged weapon, if it gets close enough for regular melee, it attaches itself to you and can only be removed by another survivor or by standing in a campfire.

Weaponry[edit | edit source]

Anything can kill it, but if you want to play it safe try to stay at a distance.

Dangers[edit | edit source]

They are a bit faster than Leeches but are difficult to overlook, given their glowing markings. If they successfully attach, unless you are already very low on health, then there is no real need to worry, as their health drain is quite minimal, they don't really obscure your vision, and their presence may actually be of benefit to you. A character with 100 HP had HP reduced to 37 HP suffering the health drain over the duration of the debuff.

Weakness[edit | edit source]

Low health, low damage. They also glow, making them easier to spot than regular leeches.

Taming[edit | edit source]

Lampreys can be 'tamed' using a Fish Basket Aberration Icon.png. However, as they lack the required intelligence, they will not return once they have latched onto someone or something.

One possible reason for taming them is to keep them around for later use for charge light or radiation protection. While a "tamed" Lamprey is not able to attach to you to provide its benefits you can unclaim them at a later time rendering them wild so they will attack and attach to you providing you their benefits for 600 seconds before falling off and despawning. You can also whistle to command a "tamed" Lamprey to attack another survivor and it will attach to that survivor.

Utility[edit | edit source]

Most of the utility to be gained comes from wild Lamprey. When a wild Lamprey attaches to you it will stay attached for around 600 seconds, draining your health at a very slow rate as well as providing the following benefits:

Roles[edit | edit source]

  • Temporary Lantern Pet: While attached to you its glowing tail will provide charge light in a radius around you. Be advised that you can't turn it off unlike having a shoulder charge light pets, making fighting Seeker harder.
  • Temporary Radiation Protection: You will be immune from the effects of radiation as long as the Lamprey is attached to you. This is useful if you do not have Hazard Suit Armor, provided you can handle its light health-draining debuff effect and its appearance on the first-person view screen.

Notes/Trivia[edit | edit source]

For information pertaining specifically to the real-world Lamprey, see the relevant Wikipedia article.

  • The Lamprey was first found in the DevKit in December 2016. However, there was no official statement on the Lamprey at the time, leaving room for speculation.
  • The Lamprey functions as the Aberration counterpart for the Leech.
  • The Lamprey is one of the few creatures in ARK: Survival Evolved that is still alive today.
  • Lamprey superficially resemble eels in that they have scaleless, elongated bodies, but they belong to a distinct family of jawless fish. Although well known for boring into the flesh of other fish to consume their blood, few are parasitic.
  • Lamprey do not produce Feces.
  • Unlike in the real world, Lampreys in ARK: Survival Evolved can indefinitely move and survive on land.
  • The environment of Aberration has forced the Lamprey to adapt, developing an ability to produce charge light.
    • This is also the only creature that exists in the real world and has been giving the capability of giving off charge light in ARK.
  • Lampreys will not attach to tames.
  • Lampreys will attack twice, with only the second attack actually hitting.
  • Gender of a Lamprey is not assigned in the game, making players unable to breed them.
  • Tamed lamprey do not have an inventory or any way for the player to feed them.
