The presence of PSTs in several of these organisms reveals that toxins produced by A. catenella are more prevalent in California food webs than previously thought and also indicates potential routes of toxin transfer to higher trophic levels. Puede una Venus atrapamoscas morir de hambre? Because the ephyra of A. aurita is a tactile predator which enhances their predation actions with increasing prey (Srnes and Aksnes, 2004), and the object of increased excretion released by A. aurita was collecting small size food (Southward, 1955), the ephyrae were exhausted when they released massive secretion and captured so many A. catenella.

Blooms of the highly toxic dinoflagellate Alexandrium catenella (previously referred to as tamarense group 1) were first detected off eastern Tasmania in 2012 and have since been responsible for incidences of human paralytic shellfish poisoning and extended closures (up to 25 weeks) of mussel, oyster, scallop, abalone and rock lobster industries (up to 150 mg/kg PST in mussels).

IntroductionThe dinoflagellates Alexandrium minutum and Alexandrium catenella are well-known producers of Paralytic Shellfish Poisoning (PSP) toxins, and have therefore received increasing attention in the last few decades because of their impact on aquaculture and human health. It contains some of the dinoflagellate species most harmful to humans, because it produces toxic harmful algal blooms (HAB) that cause paralytic shellfish poisoning (PSP) in humans.
