The Evolution of Sea Cows

Рет қаралды 535,996

3 жыл бұрын

Whereas whales are most closely related to hoofed animals like cows and deer and seals are most closely related to bears and weasels, The majority of DNA studies have shown that the closest relatives to the sirenians are the elephants. This is because they are a separate group of animals that evolved to an aquatic lifestyle on there own. But as the only fully aquatic herbivorous marine mammal they have had to over come challenges not faced by the whales and seals.

In Florida, we have very strict laws regarding the safety of manatees so seeing one in the wild always feels like a special privilege.

@beckalouhar6437 3 жыл бұрын

When I went on holiday in Florida in 2018, I stayed for 3 weeks- and I went swimming with them!! They’re so gentle!! I freaked out a bit because in person even though they’re harmless they can be pretty intimidating. But I remember just paddling calmly along the river away from the boat we came on and this manatee literally bumped into me by accident. I was like *AHHHH* in my head but then I calmed down lol it was super cute and there was a mother with it’s baby which was probably the best part- (I can’t forget the little gift shop at the end with these huge lollipops with small manatee toys attached to them aha)

@Irish Jester eh don't speak of them as "they are still wild animals". We will kill other animals without a second thought too if our child is in danger, in that regards wild animals are no different from us. Not to mention generalising that all animals have the same level of intellect is a PRETTY WRONG IDEA. Sea Mammals are not fishes, and consequently they have higher intelligence. Why do you think Killer Whales don't hunt Humans albeit them being larger than Great White Sharks and being Carnivores? Answer is simple: they feel remorse for us and don't hunt stuff that are not necessary for them to eat. This example alone should give you an idea that intelligence varies from animal to animal, and sea mammals in particular are much more intelligent.

@dplocksmith91 3 жыл бұрын

Yeah, don't feed wild animals, because it makes them less skittish around humans, and that can lead to harm. In manatees' case, they learn to hang around boats, and that can lead to them being chopped up by propellers.

We wiped out a creature as magnificent and awe inspiring as Steller's Sea Cow within 20 YEARS of discovering them... I hate humans so damn much sometimes... Sometimes I wish we never evolved, I like to imagine a world without humans where all these extinct animals are still thriving and the world is full of life everywhere. I hope in some alternate universe that's the case.

Evolution from one species to the next is childish nonsense only. Everyone with a functioning brain is aware of the simple fact.

How do sea cows actually defend themselves from sharks and other predators?

@nicks1451 3 жыл бұрын

Manatees don’t have any real natural predators so the instance of a shark or alligator attack is extremely rare.

@bri1085 3 жыл бұрын

Most sharks big enough to really be their predator are aren't really made for ther shallow water habitats.

So in the beginning Columbus saw the mermaids. I wonder how many sailors had the unwritten rule to glamourize the sea as much as possible because the ocean kind of sucks for humans. So I bet he intentionally only mentioned mermaids because it was a pain in the ass the get anyone from Europe to the americas in the first place.

Could be, but then again cute round sea cows are pretty glamorous all by themselves.

From what I understand, Steller sea cows didn’t go extinct because they were over-hunted, but because the otters in their environment were (for their fur), and it lead to an population boom of sea urchins, which outcompeted the steller sea cows for food

The hunting by humans didn't help though.

There is a great program for manatees in the Dominican Republic now. I've been lucky enough to chill out with them when snorkeling/diving. They are tracked and travel far. They are celebrities here.
