Irving the Sea Lion: From San Francisco Streets to Monterey’s Shore
7/3/2026, 11:24:24 AM
Rescued from San Francisco Streets
On April 16, 2026, a 10-month-old California sea lion pup was found on the sidewalk at 48th Avenue and Irving Street in San Francisco’s Outer Sunset. Weighing about 36 lb—roughly half the normal weight for its age—the animal, named Irving, was secured by San Francisco Police Department officers and Recreation and Parks Department rangers, placed in a dog crate, and taken to The Marine Mammal Center in Sausalito.
On-the-Ground Rescue Details
Video showed officers trying to “take a California sea lion in custody” as the animal lingered on the street. Rangers placed Irving in a dog crate and stored it in a storage area before transport. Officials and community members said they were “rooting for him.”
Rehabilitation and Weight Gain
TMMC veterinarians diagnosed malnutrition and began tube-feeding a ground-herring slurry with water and medication. Within weeks Irving switched to whole herring and was housed with another pup, Jade, to stimulate feeding. Over two months his weight rose from 36 lb to 72 lb, matching the expected mass for a healthy 10-month sea lion.
Recovery Metrics
At admission Irving weighed 36 lb, about half the typical 70-lb weight for a 10-month pup. By release he weighed 72 lb, double his initial mass. Sea-lion pups normally eat 5–8 lb of fish daily; adults 20–30 lb. TMMC has treated over 17,000 sea lions in 51 years and released 140 California sea lions in 2025.
Agency Responses
The Marine Mammal Center said Irving’s recovery shows the efficacy of its rehabilitation protocol and underscores the value of public interest in ocean health. The San Francisco Recreation and Parks Department called the pup “severely malnourished” at rescue and praised the joint effort that enabled his release. TMMC spokesperson Giancarlo Rulli said the feeding and socialization skills Irving gained should support his long-term survival.
Consistency of Reports
All sources agree on the rescue date, weight measurements, rehabilitation steps, and release location; no contradictory information was found.
