Larva Crab Worms are large purple lobster-like creatures found in Pandora. They are very distinctive because of their dark purple color. Larva Crab Worms have two large pincers at the front, and a bright purple eye in the center of their head. They have the ability to do a long-ranged corrosive attack that fires purple acid at you. They can also burrow themselves into the ground and reappear somewhere else. Nonetheless, Larva Crab Worms should not be challenging opponents due to their low amount of armor and health.
They are not fast creatures, but they do like to get up close and personal. If one of these locks onto you, it would be best to pull out a high damaging close range weapon, such as a Shotgun, so that you can get a good amount of shots on it and kill it with ease. The other method would be to use a sniper from long range and take the creature out from there, but be aware of the long ranged acid attack.
The purple 'eye' is the critical area, and does large amounts of damage. Striking this usually results in a one-shot-kill. Striking to the head by splash damage weapons can provide enormous amount of damage (up to 99999).
Another useful tactic is to use an explosive elemental weapon, as they appear to be vulnerable to that type of damage on the head and upper underbelly. Although, this may be due to the splash damage scoring a critical hit on the eye. A x4 explosive revolver is ideal for quick one-/two-shot kills.
Borderlands Guide Book Entry: Larva Crab Worms aren't as large as normal Crab Worms and they tend to not make themselves known untill their prey mistakenly gets too close. They emerge from the ground and attack by spitting venom and using powerfull claws. Keep your distance, jump around and strafe to avoid the spit attack, then shoot them in the eye.
- The "Loading" screen tips advise to use shock elemental weapons on Crab Worms.
- Killing a Larva Crab Worm leaves a large corpse on the ground that may obscure another Larva Crab Worms sneaking from behind it to attack.
- Many of the tusked skulls on Pandora resemble their head shape showing just how big they can get, which is HUGE. An example of how large some "Crab Worms" can get is shown by the boss Crawmerax the Invincible in DLC3.
- No adult "Crab Worms" are encountered in the original Borderlands, but they appear in The Secret Armory of General Knoxx DLC.
