1 The iconic lava formation just off the coast of San Cristobal known as Kicker Rock, or the Spanish León Dormido.
2 This is a gap in the bigger of the two rock formations. The area is rich marine life, such as Hammerhead sharks and various rays.
4 This is a marine iguana - recognizable by its mostly black color, its tail spines and long nails.
5 Here's a closeup of a group of Sally Lightfoot crabs, Grapsus grapsus, also known as red rock crab, and abuete negro. The bright red ones are adults. Young crabs are black or dark brown and are camouflaged well on the black lava coasts.
6 Katherine captured this image of a very bright colored Sally lightfoot crab.
7 Mosquera Islet is located between the islands of Baltra and North Seymour - it's only about 525-feet across at its narrowest width.
8 The first night on Evolution was perfect for photos.
9 Forrest caught some sea lions frolicking in the nearby waters. Katherine says the sea lions were some of their favorite animals to watch.
10 This is Santa Fe Island - the vegetation includes a dense forest of the largest species of giant Opuntia cactus.
11 Forrest got photos of several beautiful birds in flight - this is a Nazca booby, once regarded as a subspecies of the masked booby, but now recognized as a separate species.
12 This is a swallow-tailed gull. It spends most of its life flying and hunting over the open ocean, and is the only fully nocturnal gull and seabird in the world.
13 This is a swallow-tailed gull chick.
14 The brown pelican is the smallest of the eight species of pelican, but with a very large bill. It is also one of the only two pelican species which feeds by diving into the water.
15 This is a red-billed tropicbird, the largest of the three tropicbird species. Because it is a fast flier, using rapid wing-beats rather than gliding or soaring through the air, it can be difficult to photograph clearly. Forrest made it his small mission to capture a good image - and he did.
16 A male and female great frigatebird couple preparing their nest - males generally collect the loose twigs, vines and other materials, while the females manage its construction.
17 A male great frigatebird feeding its young. Very young birds are fed numerous meals a day.
18 Here is a great frigate bird chick.
19 Here is a land iguana walking on a mat of ice plants, Sesuvium, which turn red during the dry season. It is one of the most colorful plants in the Galapagos.
20 Here is a land iguana feeding on the pads of the Opuntia cactus, one of its principal foods.
21 This is Katherine Young and her husband Forrest Parker, aboard the Evolution.
22 This is a Galapagos penguin, the world's second smallest penguin species, and the only one in the world to live north of the equator.
23 Sombrero Chino, Chinaman's Hat, is a small islet off the southeastern tip of Santiago Island. A 170-foot high volcanic cone, it is named for its resemblance to the conical Asian hat.
24 The Galápagos lava lizard, Microlophus albemarlensis, is a species of lava lizard endemic to the Galápagos Islands. Adult females have a distinctive brightly colored orange-red cheek patch extending from the base of the front legs to the snout, and up to the eye.
25 A pair of "kissing" iguanas.
26 This is a marine iguana lying on solidified aa lava - such excellent camouflage. The other type of lava in the Galapagos, which looks ropy is called pahoehoe lava.
27 The Bainbridge Rocks are a group of small rocky islets off the southeastern coast of Santiago Island, not far from Sombrero Chino.
28 This is the seahorse-shaped Isabela Island, the largest of all the islands, measuring nearly 75-miles long. The dark areas are solidified lava flows.
29 This is one of the Darwin Finches, or Galapagos Finches - small land birds with dull black, brown or olive feathers with short tails, and short, rounded wings. This one is a small tree finch.
30 Charles Darwin’s Toilet is a national rock formation at Puerto Egas. This rocky pool is fed by underground channels that fill and empty with the wash of waves.
31 Here is a sea lion resting in shallow waters.
32 This is a red-footed booby. Red-footed boobies in the Galapagos come in two plumage colors - brown and white. You know it's a red-footed booby because it is perched on a tree.
33 This is a wonderful photo of a red-footed booby chick.
34 And, this is a red-footed booby adult, also perched on a branch. Forrest and Katherine were amazed at how close they could get to the animals and take photos.
35 All of these are juvenile red-footed boobies. They have adult plumage, but they haven't yet developed the distinctive red coloration of their feet.
36 A blue-footed booby resting on a rock.
37 Greater flamingos are tall, pink birds with long, lean, curved necks and black-tipped bills and a distinctive downward bend. They feed on small organisms, such as plankton, tiny fish, and fly larvae.
38 Cormorant Point on Floreana Island hosts a large flamingo lagoon. The beaches on this island are distinct: the Green Beach is named because of its green color, which comes from a high percentage of olivine crystals in the sand, and the Four Sand Beach is composed of white coral.
39 A beautiful land tortoise, classified as "vulnerable" by the International Union for Conservation of Nature. Its shell was made shiny by the rain.
40 Forrest and Katherine couldn't stop looking at all the beautiful shells. This is a shell of a Santa Cruz tortoise.
41 The tortoise is such a magnificent creature.
42 This is a small ground finch.
43 This is a brown pelican perched at the Santa Cruz pier. On this night, Katherine and Forrest took a little too long taking photos, and missed the ride to the Evolution - they had to take a separate boat back to the ship.
44 Forrest also captured some wonderful underwater photos, such as this one of two sea lions.
45 During one snorkeling session, Forrest and Katherine spotted these Hammerhead sharks.
46 Here is a golden ray, Rhinoptera steindachneri or raya dorada. These rays range in size, but they're usually up to three-feet across the wings. Golden rays are often seen swimming alone or in large schools in quiet lagoons.
47 Here is a school of golden rays on the last day of the cruise in the mangrove estuaries of Black Turtle Cove.
48 These are spotted eagle rays - identified by the dark dorsal surface covered in white spots or rings.
49 Diamond stingrays are gray with flat bodies and long, narrow tails. They lurk on the sea floor or hide in the surf.
50 This is called the famous Itabaca channel, connecting Baltra Island and Santa Cruz Island.
51 Cotopaxi is one of South America's most famous volcanoes and one of its most active ones. The snow covered symmetrical stratovolcano is located on the Eastern Cordillera of the Ecuadorian Andes, south of Quito. Thank you, Katherine and Forrest, for sharing these wonderful photos from the trip.
52 Here I am with Katherine and Forrest on Santa Cruz Island.
