Spitter

Field Notes
Alas, another hostile creature. This one's nature certainly betrays its precocious appearance. It even seems to be vexed by my retaliation. What a petulant fellow.

His snapping maw hurls orange bile. The acidic mucus must be detonated by the gnashing teeth- conceivably similar to our picric acid. Fascinating, how could this have arisen?

Post-mortem I was also able to discover the source of the creature's impressive flexibility. Aside from the skull, mandible, and teeth, the skeleton is highly cartilaginous!
