Lakelurk

Lakelurks are creatures found in the Mojave Wasteland in 2281.

Biology
Lakelurks are mutant snapping turtles who live around Lake Mead and survive in the pure water there. They attack by emitting long-distance sonic pulse waves to stun and destroy their enemies. They are fiercely territorial and aggressive, attacking anyone or anything that comes near, and are usually found in groups of two to three.

Gameplay attributes
Strangely, if they follow the player into water, they will have no underwater attacks and only glare at them. But if their sonic attack is fired from land, it will go straight through water as it does through the air, putting the player at a disadvantage of not being able to attack back. It is generally best to pick them off from a distance as they tend to swarm the player if at close range.

Locations
The unique lakelurk king is found in the Camp Guardian Caves along with dozens of other lakelurks. The largest lakelurk hotspot is Lake Mead, so the quest Volare! may be difficult for low-level players. There are also large groups at Blue Paradise Vacation Rentals and at Ruby Hill mine. 2-4 can be found down the hill from the Cap counterfeiting shack near Lake Mead. Around four lakelurks can be found on the Scavenger platform. Four more lakelurks may be discovered just south of the Hoover Dam southern fence line barrier on the eastern side of the Colorado River in a small cave area.

Lakelurk king
The lakelurk king is a stronger form of the lakelurk. While visually similar, the king has slightly glowing eyes, fins, claws, and other protrusions. Also of note is the apparent use of body 'paint' on its chest, (suggesting it may have some form of intelligence, or it may be just skin pigment). It can be found in Camp Guardian Caves in a large room among multiple lakelurk egg clutches. Killing it will cause the other lakelurks in the cave to frenzy and become hostile towards each other.

Alpha male lakelurk
The alpha male lakelurk was a subspecies of lakelurk that was to appear in Fallout: New Vegas, but was cut from the game prior to release. It is a stronger form of the lakelurk that is visually identical to the lakelurk king.

Appearances
Lakelurks appear only in Fallout: New Vegas.

Behind the scenes

 * Cachino makes a reference to Nero "sleeping with the lakelurks", the Fallout equivalent of "sleeping with the fishes", a euphemism implying death coined in older mafia films where someone would have their feet put in cement, then thrown in a body of water, hence 'sleeping with the fishes'.
 * The lakelurk appears to be modeled on the monster from the 1954 film Creature From the Black Lagoon, although apart from looks and generally hostile behavior, they share no other similarities.
