This sea lion lives along the Galápagos coast throughout the year. Its streamlined body helps it move through the water.
Males tend to be larger than females and have a bump on the forehead. The fur ranges from brown to gray, and females are generally lighter.
Understanding Galápagos sea-lion numbers requires looking beyond an archipelago-wide total to changes at individual rookeries. A southeastern survey counted 13 rookeries on San Cristóbal, Española, Floreana and Santa Fe during 2011–2015. It also examined the largest rookery, El Malecón, over 2005–2015.
Trends differed between the regional estimate and individual rookeries. El Malecón showed a slight increase during its study period, while the southeastern region overall was estimated to decline. At some rookeries, pup numbers were associated with sea-surface temperature anomalies, but sites did not respond uniformly. Keeping consistent counts at each rookery can reveal differences hidden by a regional average.
An extinction-risk assessment has not been added yet.
At 13 southeastern Galápagos rookeries, the regional estimate and individual-site trends did not move in the same way. Continued site-specific counts and examination of local environmental relationships can support conservation decisions that reflect those differences.
