1. Sentient might be a bit of a stretch regarding River Krusts.

2. River Krusts are mollusks, not plants. Mollusks are a broad group of animals that include bivalves (clams, mussels, and oysters) and and elephant tusks (I won't bother explaining). It is easy to imagine a clam (or perhaps even an elephant tusk) developing muscles to rapidly open and close their shell, and a defense (or hunting) mechanism that allowed the firing of stomach acid at range.
