Aberration survival rule #1: if you see a strange "v" in the ground, run for your life and don't look back

This legless lizard spits poison, one hit knocks you, and it loves to kill your Bulbdog named Spike

Ok, listen up they can spawn in the portal area. It killed me and friends about 10 minutes in the dlc. It just spawned in our faces.

Aggro range is crazy long. The poison is easy to dodge but I haven't been able to get away from it yet.
