MarrowGrub

MarrowGubs are viscous, carrion eating insects which infest the jungle floors of a far away, undeveloped planet. They are known to reduce a corpse to nothing within a day of death. There are cases of living creatures being infested with MarrowGub larva though ingesting tainted meat. Such cases are almost always fatal, as the first signs do not arrive until the creatures have already hatched and are busily eating their way through the host's digestive track.

Mud Grub

Mud Grubs are squat, stubby little humanoids who live in giant mud puddles. They have very rough, blubbery skin, six stubby limbs, and a wide mouth with broad teeth that are designed to tunnel through earth. They are usually non-aggressive, but will fight to the death to defend young.

Grubsucker

Large, caterpillar-like "grubs" which infest deep jungles, but have also been reported in sewer systems worldwide. In their juvenile state the Grubsucker will attach itself to a larger animal such as a rat or dog at the base of the neck. There it will feed for several months and grow larger, soon working it's way into the animal's skull where it feeds on the brain, of which it eventually bursts forth from in a gory fashion. Larger adult Grubsuckers reach a length of 2-4 feet, and will "suck" up small animals such as fish, rats, frogs, etc, although they have been known to attack larger prey as well.

Carrion Grub

Carrion Grubs are large, vicious, slow moving worm-like creatures which do nothing but eat and breed. They have extremely poor eyesight, and navigate through smell and vibration. Although they start out in a tiny larval state there seems to be no limit to the actual size they can achieve, specimens in the wild have been observed over 30 feet in length. At such a large size their diet tends to subsist on carrion (hence the name, ) or other large game. It has been theorized that they are merely the larval state of another different, larger form which has not yet been observed in nature.
