subject: The Whales And Dolphins Of The Caribbean [print this page] Whales and dolphins fascinate us; they are so foreign, yet so familiar. Their graceful ocean existence plays well off of their impressive size and features. If you're on vacation in the Caribbean ocean, then you're in luck; there are some truly spectacular whales and dolphins that you might get a glimpse of. Here are some to look for.
Risso's Dolphins are found in temperate and tropical oceans, including the Caribbean sea. Adults typically reach 10 feet in length, and weigh between 650 and 1,100 pounds; this makes them the largest dolphin species to have the word 'dolphin' in its name (Orcas, which belong to the same family, are usually referred to as whales). You can spot a Risso's by its large body, which tapers to a narrow back end and tail. They have a bulbous head, which features a vertical crease running down the front; while infants and juveniles have dark colorings around their fins, adults are mostly creamy white all over. While they're shy and rarely approach vessels, Risso's Dolphins do like to surf bow waves!
The Rough-toothed dolphin gets its name from the distinctive irregular ridges on its teeth, which help them catch and eat various houndfish, squid, octopi, and other small fish species. They're relatively large, weighing in at between 200 and 340 pounds, and reaching up to 9 feet in length. Rough-toothed dolphins can be identified by their conical heads and slim noses; unlike other species of dolphins their foreheads do not bulge forward. As social animals, they travel in pods of between ten and twenty individuals, but have occasionally been spotted swimming alone. Rough-tooth dolphins will also swim with schools of other dolphin and whale species.
If you're into rare cetaceans, then you'll have to look for the Pygmy killer whale while on your travels. Similar in many respects to Orca killer whales the dolphin has acquired this name; in fact, the Pygmy is the smallest animal that has 'whale' in its common name. It is just slightly larger than an adult man, and it has a rounded, beak-less head with white lining around the mouth. Pygmies are usually quite dark-colored, and sightings are sometimes mistaken for other species. The schools they travel in average in size of about 20 members. Pygmy Killer Whales earn their 'killer' nickname better than their larger counterparts; they've been shown to be quite aggressive against other dolphin species, and even each other. Needless to say, observe these creatures from a distance!
But by far the most incredible thing to see in the waters off the coast of the Dominican is the West Indian manatee. This species reaches about 10 feet in length, weighs between 400 and 1,300 pounds, and is colored grey or brown. It lives exclusively in the shallows of the Caribbean, though it has been occasionally found as far north as Massachusetts and in some fresh water rivers. The now-extinct Stellar's Sea Cow is only bested by this largest living manatee species.
Manatees give birth to one calf at a time, and nurse them for about 2 years. The mother and child travel together; the males contribute no parental care, although they congregate in mating herds. One subspecies, the Florida manatee, has been observed to live up to 60 years in the wild. The Antillean manatee, another sub-species, is found around the Caribbean islands, eating plants, sea grasses, and small invertebrates. Amazingly the creatures can swim upside-down and are able to do rolls and somersaults in the water with ease.
