For P. Ludroth I'm going to quote this: "The poison itself is a form of neurotoxin. A form of freshwater algae that inhabits the Misty Peaks area where these Royal Ludroth come from contains this neurotoxin, which is prevelant in the local food chain. Normally, this algae is not concentrated enough to be of any threat to the larger wildlife of the area, but Royal Ludroth eat a large amount of this algae as they grow and consume a multitude of aquatic life. Over time, the concentration of algae becomes significant enough to become concentrated to a deadly level. This concentration manifests itself in the purple tint of the Purple Royal Ludroth's skin, especially in the mane where the concentration of moisture in the spongy mane creates small blooms of the algae. In small ammounts, the algae is harmless, but when concentrated in globs of mucus it can be deadly. The Purple Royal Ludroth itself is immune to this poison, developing a natural resistance to it over time. Unlike the extremely potent neurotoxin of a Gobul, this neurotoxin is slow acting."
