UPDATE: Sea Lions in California Displaying Unusual Behavior, Scientists Concerned
Scientists are expressing worry about the strange behavior exhibited by sea lions along the California coast. These typically friendly marine creatures have been spotted bobbing their heads back and forth, foaming at the mouth, and displaying abnormally aggressive tendencies. In recent weeks, there have been reports of five attacks on swimmers.
According to experts, the root cause of this alarming behavior is a toxic algae that is poisoning the sea lion population, resulting in seizures, brain disorders, and even death. It is important to note that sea lions do not attack humans purposely out of aggression, but rather as a natural response when sick and distressed animals are startled.
Furthermore, marine mammal rescue workers have been inundated with approximately 300 distress calls per day, with over 150 sea lions found dead. As a precautionary measure, the affected beach areas have been closed to bathers, and authorities are urging people to refrain from disturbing the animals in any way, recommending a safe distance of 15 meters.
The environmental catastrophe is believed to be linked to an imbalance in ocean nutrients caused by the El Nino phenomenon and human pollution. This imbalance has led to a significant increase in the presence of microscopic plankton known as pseydo-nitzscia, resulting in the production of a potent neurotoxin called domoic acid. Fish that feed on this plankton accumulate the neurotoxin in their systems, thereby passing it up the food chain and into the stomachs of sea lions. Similarly, dozens of dolphins have also fallen victim to this neurotoxin.
Ordinarily, sea lions can flush out domoic acid from their bodies within three days. However, a high concentration of the neurotoxin in their diet can lead to their demise. In humans, exposure to this toxin can result in symptoms such as diarrhea, nausea, seizures, coma, permanent memory loss, and, in rare cases, death. Tragically, in 1927, California recorded 100 poisonings and six deaths due to the consumption of poisonous shellfish contaminated with this neurotoxin.
Scientists are diligently working to address this issue, focusing on finding solutions to mitigate the effects of toxic algae on the sea lion population. Additionally, efforts are being made to raise awareness about the importance of maintaining a healthy marine ecosystem and minimizing human pollution.
In conclusion, the abnormal behavior displayed by sea lions in California is a cause for concern. As scientists continue to investigate the impact of toxic algae on these marine mammals, it is imperative for the public to cooperate by ensuring they do not disturb or endanger these animals. By taking necessary precautions and promoting environmental consciousness, we can work towards safeguarding the wonderful biodiversity along our coastlines.
