Nematoda, The Phylum Nematoda consists of the species commonly known as roundworms. It turns out many microbes in the aquatic ecosystem also possess rhodopsin. Alexandrium catenella is an armoured, marine, planktonic dinoflagellate. Two flagella enable the Alexandrium to swim. Objective: Alexandrium catenella preforms in cold water on coastal regions and it produces toxins that cause shellfish poisoning and is also a cause of red tide. Alexandrium fundyense is a species of dinoflagellates.It produces toxins that induce paralytic shellfish poisoning (PSP), and is a common cause of red tide. Alexandrium catenella. Blooms of the dinoflagellate Alexandrium catenella recur annually during the spring, and originate from the germination of resting cysts found within the pond (Crespo et al., 2011; Ralston et al., 2014). Natural bacterioplankton assemblage composition during blooms of Alexandrium spp. Dinoflagellates Chains •Causes paralytic shellfish poisoning. These interactions, observed in algal cultures, suggest a distinct composition of the bacterioplankton during HAB episodes. Dinoflagellates of the genus Alexandrium synthesize potent neurotoxins known as paralytic shellfish poisoning (PSP) toxins. DNA probes specific for toxic A. tamarense and A. catenella and nontoxic A. affine . The relationships among these morphologically defined species are poorly understood, as are the reasons for increases in range and bloom occurrence observed over several decades.
