Stowaway

Stowaways are a stationary predator exclusive to the Downpour DLC. They reside in Subterranean, and acquire prey through ambush.

Appearance
Its body is relatively small, and mimics the texture and appearance of the tiles that it is attached to. Before being triggered, the Stowaway's body is shrunken into its perch on the ceiling, with long grey tendrils reaching down to the floor that act as sensors. When triggered, the body suddenly juts out and opens its maw, revealing 5 jagged faded pink teeth. 3 Long pinkish grey tentacles will drop down from inside the mouth, almost four times the length of its body. These tentacles each have a jagged hook at the end which it uses to grab the player and eat it.

Combat
Fighting against Stowaways can be very tricky, as they're near invisible ambush predators with a fast attack. However, you can dispatch a stowaway before its ambush is activated. It can easily be killed using a from a distance. Hitting a Stowaway's body with  will reveal its location, making it easier to avoid or kill. If the ambush attack is activated and successful, things get significantly more complicated. The Stowaway's 3 tentacles will constantly attack a creature, keeping it in a stunned state, but it ceases this when it starts to pull its prey towards its mouth. Much like and, a  thrown into a tentacle causes the Stowaway to release its grasp. Will cause every Stowaway in the area to release their tentacles, before quickly retracting them. Cherrybombs also cause Stowaways to release everything in their grasps.

Like the other Arthropods, a can kill Stowaways

Evasion
Evading a Stowaway is a much simpler task, the ambush attack is only initiated if a creature is touching its sensory tendrils for a prolonged period of time, quickly passing underneath a Stowaway is enough to evade it. In the case that its ambush is initiated, its tendrils can be avoided by quickly running to one side of it until you're out of the Stowaway's reach. Creatures can be thrown or lured into the tendrils to activate them prematurely. Since the Stowaway will only focus on one creature at a time, this can be used for safe passage while it's distracted.
