Rockgrub: The Smallest Survivor on 4546B 🪨🌊

Added: 2026-05-28

[00:00:00]The trick to surviving the largest carnivores is to be too small for them to worry about.

[00:00:06]The rock grub is a tiny luminescent scavenger that feeds on clumps of sea grass and coral caught in the rocks amongst its habitat.

[00:00:16]Having both a tail and legs, the rock grub is fast on both the ocean floor and the open water, making it a less than easy meal for any small carnivores.

[00:00:27]The one thing the rock grub has going against it, however, is its bright green glow, painting a target on its back.

[00:00:36]It's currently unknown what the evolutionary reason of this glow is, but it may possibly be used in a form of mating behavior.
