The Evolution of Sea Cows

[@nicks1451]

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]

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)

[@chronoshindou9848]

@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.

[@dilungmoveityafool777]

A good example is the Trump thing that happened recently.

[@dplocksmith91]

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.

[@dplocksmith91]

(In case you didn't know, "cracker" is the word referring to someone who was born in the state of Florida, though it's used by a lot of people these days to describe white people)

If capybaras had their way, they could become the next mammal to become fully aquatic. I wonder if the beaver or even the nutria/coypu are already on their way of getting there.

[@duneydan7993]

Beavers are still fairly terrestrial and I don't think they will evolve towards full aquatic as the main reason of their succes is their ability to creat dams.

[@richarddr1234]

I would argue that hippos would adapt to fully aquatic life first.

[@chrissmith3587]

@@duneydan7993 additionally the beavers teeth constantly grow, meaning they would die if they don’t wear down their teeth, this isn’t possible at sea While it could happen it would need a long transition as to loose this ability removes the ability to create dams which are essential to beavers

Probably because there aren't that many large marine plants, since the majority of photosynthetic organisms in marine environments are free floating single celled organisms and not the large leafy plants which colonized land. Also, while many animal lineages have made the pilgrimage back to the sea, only a small handful of true plants have adapted for a marine existence.
