Nematode
Nematodes are a 
Cod Worm variant encountered in Corpse, and spawn stationary and hidden like their counterparts. However, unlike Cod Worms, they are not invulnerable while hidden, but will take 1/3 damage. If attacked when hidden, Nematodes launch out 3 arcing chunk projectiles in a triangle pattern, and then fire 4 projectiles in the ordinal directions. The chunks burst into 3 teeth projectiles, lobbed towards Isaac when they hit the ground.
After awhile, when their head pops out, they will pause a moment before firing 3 quick consecutive projectiles, each aimed towards where Isaac is moving, attempting to cut him off. They will remain vulnerable in this state for a few moments after before retreating into their shell.
Upon death, they fire a small burst of blood and tooth projectiles towards Isaac and spawn 3 
Toma Chunks. If they were hidden when killed, they also spawn a 
Para-Bite.
Trivia
- In the original Morbus MOD, Nematodes were just Cod Worms' appearance when encountered in Morbus, with no differences in behavior.
