Answered by praseethanerthethil

Answer:

Saxitoxin is a neurotoxin naturally produced by certain species of marine dinoflagellates (Alexandrium sp., Gymnodinium sp. Pyrodinium sp.) and freshwater cyanobacteria (Anabaena sp., some Aphanizomenon spp. Cylindrospermopsis sp Lyngbya sp., Planktothrix sp.)

Explanation:

Saxitoxin is produced by the dinoflagellates Gonyaulax, Alexandrium, Gymnodinium, and Pyrodinium. Similar to tetrodotoxin, saxitoxin binds to voltage-gated sodium channels within cell membranes, inhibiting membrane depolarization and blocking proliferation of action potentials.
