Dolphins in the Galapagos Islands are known for their wacky and inquisitive dancing, which often mesmerizes fortunate tourists. They are also known for their vibrant nature and aquatic lifestyle. For us somewhat “self-interested” mammals, these fantastic species are wonderfully kind and have unique ways of making the animal kingdom feel less exotic. When a mirror is placed in front of them, they will gladly display their camaraderie with other creatures and one other. They even possess highly developed mechanisms that enable them to employ echolocation to locate their surroundings. What’s the best thing, then? The Galapagos is no stranger to these creatures.
Which dolphin species can be spotted in the Galapagos?
Throughout the archipelago, dolphins of five different species have been observed. Two of these, the Common dolphin and the Bottle-nosed dolphin, spend the entire year in the Galapagos. Only during their migratory season can one witness the other three species of dolphins—the Spinner, Risso’s, and Pantropical Spotted dolphins—throughout the islands.
Key Information About This Stunning Species
Dolphins are aquatic mammals in the cetacean order’s paraphyletic group. Paraphyletic refers to deriving from the last common ancestor of the order. The average lifespan of a dolphin species is 25 years. However, certain Bottle-Nosed species have been recorded to reach 50 years of age. They vary widely in size, with the famed killer whale—also a member of the dolphin family—measuring up to 9.5 m (31 ft) and weighing as much as 10 tons, and the Maui dolphin reaching up to 1.7 m (5.6 ft) and 50 kg (110 lb).
Some dolphin species, like the Right Whale dolphin, prefer colder climes, even though most prefer warm tropical waters. While female dolphins mate every two to three years, males mate with multiple females yearly. The mother dolphin is the exclusive caregiver for her young after giving birth, typically in spring or summer.
Fish and squid are the dolphin’s primary food sources, but its larger cousin, the orca wheel, also consumes large mammals like seals. A day, dolphins can consume up to 33 pounds of fish. Unlike other aquatic animals, dolphins breathe via a blowhole on their backs that functions similarly to a nose. Dolphins require oxygen to survive since they have lungs, and if they go for particularly long dives, they may need to come to the surface as often as every 15 minutes. As only one-half of their brains sleep while the other is awake, breathing is not an automatic process for them. As a result, they must “sleep” at the surface for their blowholes to continue breathing.
Common Dolphins in the Galapagos Islands
Alternatively, and ironically, known by its scientific name, Delphinus delphis, it is less common than its Bottle Nose cousins. The dark stripe from their flipper to their chin is the most straightforward method to identify them. Furthermore, unlike the two-toned Bottle Nose dolphin, the Common dolphin has a single color. The two types of Common dolphins found in the Galapagos are the long-beaked and the short-beaked species. They can number anywhere from a few dozen to a hundred and are very adaptable creatures that love to leap and splash around in groups.
Bottle-nosed Dolphin
Tursiops truncates is another name, often spotted swimming and playfully jumping alongside guests’ boats and other small motorized vehicles. They have developed an additional fat coating in their body, known as blubber, to help them stay warm in the islands’ colder waters. Their hue transitions from a light grey or white at the bottom to a blueish-grey at the top. Thanks to their torpedo-like form, they can reach swimming speeds of up to 48.3 km/h (30 mi/h). They are also renowned for their highly acrobatic movements, which frequently turn them into a spectacle for tourists lucky to see them while traveling.
Stay Alert
These remarkable creatures remain one of the most rewarding spectacles you can be treated to while on your expedition vessel in the Galapagos. Peer over the side of the boat on the Galapagos as we’re moving along, and who knows? They might be there, swimming alongside us, maybe even wondering what we are like, the same way we marvel at their ways.
