In a concerning surge of marine wildlife emergencies, nearly two dozen sea lions have been rescued from the shores of Ventura and Santa Barbara, poisoned by a neurotoxin associated with an algal bloom. As reported by CBS News, these incidents have erupted over the past week, with responders receiving up to "100 reports a day" about afflicted sea lions across the numerous beaches.
Typically, the adult female sea lions, have been affected by domoic acid produced during harmful algal blooms, commonly referred to as "red tides", according to CBS News. This toxin accumulates in smaller fish that do not suffer the effects but can cause significant damage to predators that consume them. CIMWI detailed the range of troubling symptoms evident in distressed marine animals, including seizures, disorientation, head weaving, and lethargy. Despite the ability of domoic acid to naturally flush from an animal's system, repeated exposure can have dire consequences, leading to more permanent afflictions.
A similar scenario has unfolded in SoCal beaches, where affected sea lions, following ingestion of shellfish and small fish laden with the neurotoxin, have exhibited a bevy of disturbing symptoms as listed by the CIMWI press release shared by KTLA. Such symptoms include but are not limited to, involuntary muscle spasms, stargazing or staring into space, and an alarming inability to move away from the tidal zone. Officials have reiterated the importance of keeping a respectable distance and contacting local rescue services immediately, in order to best assist these vulnerable sea lions in their recovery.
