This morning, we are off to Arcadia, Florida, to meet our friends, Tom and Lois, who visited us in Marloth Park, South Africa, in October 2018. It’s a 90-minute drive for us and a little more for them, and we appreciate them driving to meet us for lunch at a popular inland restaurant.
We’d hoped to see many more friends and family members while in Florida but after we changed our trip to come to Karen and Rich’s wedding due to Omicron, our timing changed considerably and there just hasn’t been enough time. We apologize to all those special people we won’t have an opportunity to see this time around but with our passion for cruising, surely we’ll be back in Florida at some point in the future. Also, after the pandemic, car rental prices are outrageous in Florida with limitations on mileage, something we haven’t experienced in the past. Driving all over the state would have cost thousands extra.
Thus, today, for time’s sake, we’ve included Part 2 of the manatee story, which I mostly prepared yesterday, to ensure we are on the road promptly at 10:15 am to meet them by noon, leaving a little extra time for traffic. We plan to return to Karen and Rich’s by 5:00 pm for a barbecue rib dinner Rich is making. It will undoubtedly be a busy and fun day with friends.
We found this excellent information about manatees from the Smithsonian’s website here:
14 Fun Facts About Manatees
These roly-poly herbivores, just maybe the teddy bears of the sea. But keep an eye out when boating; they don’t move so fast. Emily Frost
Despite their size and stubbly snout, manatees seem cute and cuddly to many ocean visitors. These large, slow-moving marine mammals hang out in coastal areas and rivers where Florida spring-breakers can easily see them and think it is good to hop on for a ride. Not only is this and other forms of harassment such as hugging the sea creatures illegal (the West Indian manatee is listed as endangered in the United States), but it can also impact manatees’ natural behavior, changing the way they interact with humans.
All three species of manatee—the Amazonian manatee, West Indian manatee, and West African manatee—and the related dugong are considered vulnerable (defined as facing a high risk of extinction in the wild) by the IUCN Red List of Threatened Species. This is due to a variety of threats, including boat collisions, hunting, habitat destruction, and toxic red tides.
4. Manatees go to the surface of the water every three to five minutes to breathe, although they can remain underwater longer, holding their breath for up to 20 minutes. When they do take a breath, 90 percent of the air in their lungs is replaced (whereas humans tend to replace about 10 percent).
5. The Amazonian manatee (Trichechus inunguis) lives entirely in freshwater rivers throughout South America in the Amazon Basin. It is hard to estimate their numbers due to their secretive nature and the murky water where they often live. A fourth dwarf manatee species was described in the mid-2000s, but this claim was called into question, and it is believed actually to be a juvenile Amazonian manatee. The main threat to this species is illegal harpoon hunting for subsistence.
6. Dugongs (Dugong dugon), in the same order (Sirenia) as manatees, spend all of their time in the coastal ocean waters of the Indian Ocean and western Pacific. They don’t ever venture into freshwater. Although they look similar to manatees, dugongs have a more whale-like fluke than the round, paddle-like tail you see on manatees.
The fossil record shows a much more diverse group of sirenians than we have today, with dugongs and manatees living together throughout their range. 7. The closest living relatives of sirenians are elephants. Manatees evolved from the same land animals as elephants over 50 million years ago.
8. Humans have one round of baby teeth, and then if we lose or hurt an adult tooth, a trip to the dentist is in order. Manatees, like their elephant relatives, continuously replace their teeth throughout their lives, with the older teeth at the front falling out and new teeth growing in at the back of their mouth.
9. Researchers believe that the now-extinct Steller’s sea cow (the largest member of the order Sirenia) was at one point found throughout the Pacific, in waters off Japan and the U.S. west coast. In 1741, Georg Wilhelm Steller first described the sea cow from islands off the coast of Russia (in what would later be called the Bering Sea) as subsisting off of kelp and not being able to submerge underwater. Within 27 years of first being described, the species was driven to extinction by hunting and competition for their kelp food source with an exploding urchin population.
10. Christopher Columbus and other early explorers claimed to have seen female figures swimming in the ocean—the mermaids in the writings and drawings of this era. Whether they had been at sea for too long or it was a trick of the light, we now know that many of these encounters were with manatees.
11. Manatee brains are smooth (compared to our own, have the familiar ins and outs of cortical folds), and the ratio of their brain to their body size is the lowest of any mammal. They may not be as clever as dolphins, but manatees can learn basic tasks, are extremely sensitive to touch, and can differentiate colors.
12. Female manatees usually have one calf every two to five years, and the calf then stays and nurses for two years. Calves nurse from their mother’s teats, which are found right where the forward limbs meet the body. The calves also can start nibbling on plants at only a few weeks old.
13. If you are a mammal—whether that’s a human, giraffe, whale, or rat—then you typically have seven neck vertebrae. Only tree sloths and manatees have an irregular number of vertebrae—just six for the manatee. Scientists think this may have to do with their slow metabolism.
14. Manatees have no natural predators in the wild, but humans have played a large part in making all three species at risk of extinction. About half of West Indian manatee deaths are caused by humans, and most are due to boat collisions. Manatees are quite buoyant and use their horizontally placed diaphragm and breathing to control their buoyancy. This and their average speed of 3 to 5 miles per hour means that manatees are way too slow to escape from the path of a speeding boat.”
Mother Nature never ceases to amaze us. What unusual and exciting animals! Please stay tuned for more as we move toward our next adventure, one week from today, sailing across the Atlantic Ocean on our first cruise since the onset of the pandemic.
Have a fantastic day!
