Galápagos Fur Seal

Fascinating facts about the Galápagos Fur Seal

• Around the late 1970s, scientists counted roughly 30,000 Galápagos fur seals, a number that seemed to signal recovery after centuries of hunting. Yet the 1982-83 El Niño slammed the population, wiping out almost every pup and killing about 30 % of adults. That single climate event erased a generation and showed how a brief spike in sea temperature can plunge an already limited species toward the brink, underscoring the fragility of their island-bound numbers.
• Galápagos fur seal mothers nurse a single pup for up to three years because pups cling to milk for the first eighteen months and weaning can stretch to two or three years when food is scarce. Up to 23 % of births occur while an older sibling still suckles; in lean years, 80 % of those younger pups die within a month. This high-stakes "insurance" strategy reveals how unpredictable ocean food supplies force mothers into a gamble between current and future offspring.
• When darkness falls, Galápagos fur seals dive up to 169 m (554 ft) to chase fish, squid and shellfish that rise toward the surface, preferring night hunts because prey are easier to catch. Typical dives are only 10-30 m deep and last about 16 hours, but the seals can plunge far deeper when needed. Their nocturnal foraging habit highlights a unique adaptation to the tropical seas, where daylight hides prey and night opens a feeding window.
• At just 1.5 m long and 64 kg, male Galápagos fur seals are the tiniest of all eared seals, while females tip the scales at only 1.25 m and 27 kg, a size gap that makes them the smallest otariid on Earth.
• Male Galápagos fur seals carve out beach territories averaging 200 m² (2,200 sq ft), a plot larger than most otariid males defend, to attract females. These spacious patches let several females gather.
