Although both the Gal\u00e1pagos fur seal and the Gal\u00e1pagos sea lion live on the same islands and look somewhat alike, they are actually different species with unique traits. <\/p>\n\n\n\n

The\u00a0Galapagos fur seal\u00a0belongs to a genus of fur seals called Arctocephalus (or Arctophoca), meaning bear-headed. The\u00a0Galapagos sea lion<\/a>\u00a0belongs to the genus Zalophus, which contains two extant sea lion species, and previously contained the Japanese sea lion, which went extinct in the 1970s.<\/p>\n\n\n\n

Fun Facts<\/strong><\/h3>\n\n\n\n
    \n
  • Gal\u00e1pagos Fur Seal<\/strong> is the smallest fur seal species in the world.<\/li>\n\n\n\n
  • Gal\u00e1pagos Sea Lions<\/strong> are curious and often approach snorkelers and swimmers.<\/li>\n\n\n\n
  • You\u2019re more likely to see sea lions<\/strong> out and about\u2014they\u2019re noisy, bold, and often sunbathing.<\/li>\n\n\n\n
  • Fur seals<\/strong> are elusive, quiet, and prefer cooler, shaded crevices.<\/li>\n<\/ul>\n\n\n\n

    Summary<\/strong><\/h3>\n\n\n\n

    If you spot a sleek, loud animal basking in the sun or swimming playfully near a boat\u2014it\u2019s likely a Gal\u00e1pagos sea lion<\/strong>. If you see a smaller, darker creature tucked away in a shadowy rock crevice\u2014it\u2019s probably a Gal\u00e1pagos fur seal<\/strong>.<\/p>\n\n\n\n

    Despite sharing a habitat, these two species avoid competition by having different hunting times and preferences. They’re both vital parts of the Gal\u00e1pagos ecosystem and are protected under Ecuadorian law.<\/p>\n\n\n\n
