Galapagos Islands (Part 2)

Galapagos 20 Approaching Storm

The volcanic archipelago making up the Galapagos Islands is relatively young by geological measures and on some of the newer islands you may see only the initial stages of plant life.

A Cactus Plant Finds a Spot on a Lava Formation

One of the strange aspects of volcanic activity is the formation of lava tubes.  Don’t ask me for an understandable explanation, but it has to do with the lava flow cooling and becoming hard on the surface, while still-hot lava continues to move under the hardened surface.  In some cases, when the eruption ends, the last of the moving lava proceeds through the channel, draining it and leaving a long cave behind.

The tunnel was interesting but very dark and creepy, a great location for a horror movie. And it was the wildlife we wanted to see so not a lot of time was spent there.

Galapagos 28 Sea Lions and iguana

The Galapagos marine iguana is the only iguana that has evolved from a strictly land-based creature to one that swims and feeds in water.  They are found nowhere else on the planet.  They feed on ocean algae, often fully submersed, and even have a special gland common to marine birds that enables them to extract excess salt from their blood and sneeze it out several times a day.

The sea lions found in the Galapagos Islands are the smallest of the sea lion species.  The female gives birth to a single pup a year after mating and she stays with it for the first week after birth.  She then will depart for one to four days to hunt, while other females of the colony stay behind to watch over the youngsters.  Eventually, the pups join their mother to develop swimming and hunting skills.

The smaller birds, such as the Galapagos mocking bird, were more timid than most of the island wildlife but they still provided photo opportunities on occasion.  Interestingly, there are seven subspecies of the Galapagos mockingbird, and each one seems to be largely endemic to different islands of the archipelago.  Apparently, it was the differences (such as beak size and shape) among these birds, as well as his better known study of the Galapagos finches (15 subspecies) that sparked Darwin’s thinking about adaptive evolution.
