Momentarily distracted from its sleep by humans, this sea lion lifts its head to check out what is going on
Slightly smaller than their Californian relatives, Galápagos sea lions range from 150 to 250 cm (59 to 98 in) in length and weigh between 50 to 250 kg (110 to 550 lb.), with the males averaging larger than females. Most of the sea lions we encountered during the day seemed to be sleeping.
The beauty of the Swallow-tailed Gull captured in flight
The Swallow-tailed Gull breeds mainly on the Galapagos Islands. It forms loose colonies with large inter-nest distances but can be solitary, nesting on steep slopes or broken cliffs, often on broad cliff-top ledges but also just above the wave line, and on gravelly beaches and under vegetation.
In the breeding season, the adult has a black plumaged head and a bright red fleshy rim around each eye.
The Magnificent Frigatebird is 100 cm (39 in.) long with a 215 cm (85 in) wingspan. Males are all-black with a scarlet throat pouch that is inflated like a balloon in the breeding season. The contrast between the inflated versus deflated pouch above is striking.
The frigatebirds are a family of seabirds also sometimes called Man of War birds or Pirate birds. Since they are related to the pelicans, the term “frigate pelican” is also a name applied to them. They have long wings, tails, and bills and the males have a red gular pouch that is inflated during the breeding season to attract a mate.
The Galapagos marine iguana is an iguana found only on the Galápagos Islands that has the ability, unique among modern lizards, to live and forage in the sea, making it a marine reptile. The iguana can dive over 9 m (30 ft.) into the water. It mainly lives on the rocky Galápagos shore, but can also be spotted in marshes and mangrove beaches.
