An 18-year-old man from California has admitted to unlawfully harassing a sea lion, an act captured on video that subsequently gained widespread attention online. Tyler Muehl, hailing from La Jolla, pleaded guilty to a misdemeanor in violation of the Marine Mammal Protection Act on Thursday, August 13. This legislation prohibits the harassment of marine wildlife, an infringement Muehl admitted to in a formal statement.

The incident occurred on the evening of July 22 at La Jolla Cove, a popular coastal area known for its marine life. According to court documents, Muehl approached a California sea lion lounging on a sea wall located near Ellen Browning Scripps Park. Witnesses reported that as Muehl closed in on the animal, he assumed a boxing stance, stating he was mimicking UFC fighter Max Holloway.
In his plea agreement, Muehl admitted to kicking the sea lion in the face multiple times, causing noticeable distress to the creature. The first two kicks prompted the animal to flinch and recoil, illustrating the immediate impact of Muehl’s actions. As the sea lion attempted to flee the scene, Muehl pursued it, delivering a third kick and forcing the animal to stumble.

The young man continued his aggression with a fourth kick as the sea lion scrambled over the sea wall and made its way onto the beach. This confrontation was captured on video, which later circulated widely on social media, leading to public outrage and condemnation of Muehl’s behaviour. Under the terms of his plea agreement, Muehl acknowledged that the video accurately depicted the events that transpired.
Muehl’s actions fall under the definition of “taking” a marine mammal, which, according to the Marine Mammal Protection Act, includes harassment that poses the risk of injury or disturbs the animal’s natural behaviour. The ramifications of his actions have highlighted the seriousness of wildlife protection laws.

U.S. Attorney Adam Gordon commented on the gravity of the situation, stating, “Federal crime. Federal consequences.” He emphasised the importance of adhering to laws designed to protect marine mammals from harm and maltreatment.
Eric Morgan, the assistant director of NOAA Fisheries’ Office of Law Enforcement West Coast Division, added, “Intentionally striking or kicking a marine mammal is not only illegal—it is dangerous for the well-being of the animal.” Such commentary underscores the broader implications of Muehl’s actions, not only for the individual animal but for marine life as a whole.
As a result of his guilty plea, Muehl faces the possibility of up to one year in prison, in addition to a potential $100,000 fine. His sentencing is scheduled to take place before U.S. Magistrate Judge Jill L. Burkhardt on October 20.
This case serves as a stark reminder of the ongoing challenges in protecting wildlife and the need for adherence to regulations aimed at safeguarding marine creatures from human interference. The reaction to Muehl’s conduct illustrates a growing public sensitivity towards the treatment of animals in their natural habitats and a collective call for accountability in instances of animal abuse.
