Galapagos Marine Life


The combination of warm tropical waters and the upwelling, nutrient rich, Humboldt Current allows the Galapagos Islands to support a wide array of marine life. These waters are home to sharks, sea turtles, sea lions, and 306 species of fish, 25% of which are endemic. There are few reef building corals in these waters but numerous crevasses in the lava serve some of the same functions as a reef in other environments. Smaller fish and invertebrates make their home in the lava and larger fish live near the lava area where they feed on the smaller fish.

Viewing the Marine Life


Diving in the Galapagos has been rapidly increasing in popularity over the last few years. These trips often visit some of the remote island areas, like Darwin and Wolf, where land visits are not possible, but diving is exceptional. The highlight of these trips is viewing the Galapagos' big animals including Whale and Hammerhead Sharkes.

Natural history cruises offer snorkeling excursions in place like the Devil's Crown, a submerged volcano, which offers an experience similar to that of swimming in a tropical fish tank.



Sea Turtles


The Pacific Green Sea Turtles spend most of their lives in the ocean. Adults grow to more than 3 ft (1 m) in length with a body weight of up to 400 lbs. (180 kg). These cousins to the tortoise mate in the waters near the Galapagos and are often seen near Caleta Tortuga Negra on Santiago. Males never leave the sea, but females come ashore on beaches to nest. Green Sea Turtles are an endangered species. Turtle nests are destroyed and the eggs are eaten by humans, pigs, rats and dogs. Hawks, herons, mockingbirds, and frigatebirds prey on young hatchlings. If the young turtles make it to the sea, large fish and sharks hunt them.

Whales & Dolphins


During the19th century whale oil was an important source of lamp oil and used around the world. Whales, dolphins and porpoises all have a blubbery layer of fat around their body which allows them to stay warm in cold waters and provides them with extra energy during long migrations. It was this blubber the whalers sought and they would melt it down to produce whale oil. Due to the richness of the seas near the Galapagos Islands, whales migrate here to feed and for a time these island were the center of the whaling industry in the Pacific Ocean. The practice of whaling has nearly stopped and many of these large mammals still visit the Galapagos during their migrations. Whales, Dolphins and Porpoises make up the family of Cetaceans which can be divided into 2 groups; those with teeth and those with Baleen Plates.

Baleen Plates are large, horny triangular pieces of whalebones that grow on the upper jaws of toothless whales. Baleen whales push seawater through these plates straining out the plankton, shrimp, sardines and other small creatures on which they feed. Baleen whales are the world’s larger animals and include the Blue, Finback, Sei, Humpback, Bryde's and Minke Whales, all which can be seen in the Galapagos waters.

Toothed Cetaceans are a more diverse group and include the Sperm Whale, Orca, False Killer Whale, Short Finned Pilot Whale, and several species of Dolphins. All are frequently seen in the waters surrounding the Galapagos. Bottled Nosed and White Bellied Dolphins are common here and may often be seen riding the bow wave in front of boats. White

 

Birds


Long known as a haven for birders, the Galapagos Island's native bird life includes 57 residents almost half of which are endemic. Darwin's Finches include 13 species that have adapted to their specific island setting. Other endemics include the Lava Gull, Galapagos Penguin, Dark-Rumped Petrel, Galapagos Flightless Cormorant, Lava Heron, Galapagos Martin and Galapagos Dove.

In addition to the permanent residents more than 700,000 migratory sea birds can be seen in the islands. The Galapagos is home to almost 1/3 of the world’s Blue Footed Booby population, the highest concentration of Masked Boobies and the largest colony of Red Footed Boobies.



Darwin's Finches


The Galapagos Islands is home to 13 species of finch, belonging to 4 genera. These finches are thought to have all evolved from a single species similar to the Blue-Black Grassquit Finch Volatina jacarina commonly found along the Pacific Coast of South America. Once in the Galapagos these finches adapted, over time, to their specific habitats and the size and shape of their bills reflect their specializations. The Vegetarian and Ground Finches have crushing bills, the Tree Finch has a grasping bill and the Cactus, Warbler and Woodpecker Finches have probing bills.

All of Darwin's Finches are sparrow sized and similar in appearance with gray, brown, black or olive feathers. They have short rounded wings and a rounded tail that often appears cocked to one side. They vary in diet, some eating seeds and others insects. Ground Finches eat ticks they remove with their crushing beaks from Tortoises, Land Iguanas and Marine Iguanas and they have been known to kick eggs out onto rocks where they feed on their contents. On Isla Wolf the Sharp Beaked Ground Finch is known as the "Vampire Finch" as it has been known to jump onto the backs of Masked and Red-Footed Boobies pecking at their flesh and feeding on their blood. Woodpecker and Mangrove Finches sometime use small twigs and cactus spines as tools to probe for insect larva under bark and in dead tree branches.

Though each species of finch has adapted to a specialized feeding pattern, most are generalized eaters. These specialized adaptations are of survival importance during the dry season and in times of drought when little of their preferred food is available. It is during these stressful times that these specialized tools allow the birds to compete for limited food resources with other birds and animals.

RECOMMENDED READING

An excellent way to prepare for your visit to Ecuador and the Galapagos Islands is to read about them. Knowing something about the history, culture, people, food, shopping, wildlife and places of interest can make your trip more enjoyable and provide you with a much richer experience. Novels written by indigenous authors often give valuable insights into the people and their cultural and social values.

Not specific to Ecuador or the Galapagos but a really excellent book that will provide much information is "Guns, Germs and Steel" by Jared Diamond. 1999. W.W. Norton & Co. ISBN 0-393-31755-2. I rate this as one of the best background books I have ever read. The following is list of authors and titles that you may wish to consider reading in preparation for your expedition.

BEWARE OF ENDANGERED WILDLIFE PRODUCTS


GUIDELINES FOR TOURISTS, Prepared by TRAFFIC (U.S.A.)

Some attractive items offered for sale abroad are made from the hides, shells, feathers and teeth of endangered wildlife. Although some of these may legally be bought in other countries, U.S. and international laws may make it a crime to bring them back into the U.S. Before buying wildlife items, exotic pets, or plants, check to be sure that it is legal to import it into the U.S. Illegal items may be confiscated by U.S. customs or wildlife inspectors and significant fines levied.

The following information provides some guidelines with regard to illegal wildlife and wildlife products that may be for sale abroad.

Reptile Skins and Leathers

Products made from skins of crocodiles are common in European and Asian marketplaces, but most may not be imported into the United States. These include products of the black caiman, American crocodile, Orinoco crocodile from Latin America and the Caribbean, the Philippine crocodile, the Chinese alligator and the African Nile crocodile.

Products made from Latin American caimans and crocodiles are also very common in Europe, but are likely to be illegal. Caimans are protected in most of the countries in which they occur. Caiman products made from skins originating in Colombia, French Guiana, Guyana and Suriname may be legal. However, the illegal quantities of skins from this region far outweigh the legal quantities.

Most South American lizard skin products may be brought into the U.S. Exceptions are those originating in Brazil and Paraguay, which ban their export. A number of Asian countries, including India, Nepal and Pakistan, protect lizards, so products from Asian lizards, especially the popular monitors, may be illegal.

Snakeskin products made from large, boldly patterned species like boa constrictors, anacondas and pythons, as well as from smaller snakes, are popular here and abroad. In general, you may import snakeskin products. However, Latin America, Brazil, Ecuador, Mexico, Panama and Paraguay prohibit the export of snakeskin, making it illegal to import products made from skins originating in these countries. You may also encounter problems with skins from certain Asian countries, such as India, which permit only a limited trade in products finished in that country.

All sea turtle species are protected under U.S. and international law. Sea turtle shells, shell jewelry, leather, eggs, meat, and creams made with sea turtle oil cannot enter the U.S. legally.



Furs - Furs from ranched animals that may be brought into the U.S. include mink, chinchilla, nutria, ermine and some fox.

Furs of wild beaver, raccoon, opossum, fox, coyote, North American river otter, bobcat and lynx may also be imported into the U.S.

Furs from large spotted cats such as jaguar, leopard, snow leopard and tiger, and from smaller spotted cats such as ocelot, margay and tiger cat, may not be imported into the U.S. In fact, very few spotted cat skins can enter the U.S. legally.

Birds and Feathers -The importation of wild bird feathers, mounted birds and skins (with or without feathers) is prohibited by U.S. Law.

-Many large parrots, including certain macaws and cockatoos, are protected in their country of origin and may not be imported into the U.S. Birds originating in Australia, Brazil, Mexico, Paraguay and a number of Caribbean countries may not enter the U.S., nor may many birds of Indone­sian origin. Check carefully the legal status of colorful birds before you buy.

-Live birds, if they can be imported into the U.S., must go into quarantine under regulations of the U.S. Department of Agriculture.

Ivory -Ivory from animals, including whale, walrus and elephant, is barred from import into the U.S.

Coral -Many countries either prohibit or restrict the collection, sale and export of corals, whether in raw form or worked into jewelry.

Plants - Plants, such as cycads, orchids and cacti, are either prohibited from import into the U.S. or their import is restricted. Whether endangered or not, all plants must undergo inspection by the Department of Agriculture and be accom­panied by docu­ments certifying they are free of disease and pests.

Wildlife Curios from Mexico-Stuffed caimans, crocodiles, birds, turtles and other wildlife curios that you might find for sale in Mexico are almost certain to be confiscated by Customs or wildlife inspectors. It is best to avoid these items.
For further information regarding illegal live wildlife or wildlife products, contact TRAFFIC (U.S.A.), the Fish and Wildlife Service of the Department of the Interior, or the U.S. Embassy if you are abroad.

TRAFFIC (U.S.A.) - Trade Records Analysis of Flora and Fauna in Commerce - is a program of World Wildlife Fund-U.S. and part of an international TRAFFIC network cooperating with the International Union for Conservation of Nature and Natural Resources to monitor the international trade in wild plants and animals.
