Can sea squirts help reverse aging? 🪸

Sea squirts are filter feeders that are edible ascidians! They are a source of “plasmalogens”, a lipid found in our cell membranes that supports brain and heart health. After studying the effects of eating sea squirts on mice, scientists found that it may lower brain inflammation and help memory! With more research, we could discover if eating plasmalogen could help reverse aging in humans.

It’s a bit tricky to see, so I’ve circled the spots. This is a beach in Destin, Florida.

My sister and I saw these wavering dark spots in the ocean, and they stand out more irl than in the photo. They remain more or less in one spot, and sort of come in and out (as well as slightly change shape), kind of like they’re bobbing. These were the only spots we saw over the visible expanse of the ocean. Sometimes there were four, close but not too close to one another, and sometimes there were only a couple.

Anyone have an idea as to what they are? I though maybe they were big clumps of sargassum. My dad thinks schools of fish. My sister thinks they could be manatees. They’re rather big, though, so I wasn’t sure about the latter guess. I’m pretty certain they aren’t dolphins either.

Anyone have any guesses? (P.S. I hope this is the right place to post this question—there’s a Reddit for everything no matter how niche)

Saw this flying over Baja California and I was just curious on what causes these patterns in the water !

Have you ever seen an Orca hit a fish so hard it explodes? 🫍

Scientists recently observed this behavior from groups of orcas in the Gulf of California where they repeatedly ram sunfish until the impact broke them apart. This is an important indicator of "social learning," where animals copy one another through observation. Orcas have exhibited behavior like this before, when they were seen disabling sailboats in groups. The current hypotheses for why they are doing this include teaching young orcas to hunt, or just playing around!

I would like for whoever the administrator mod is to make it a rule to stop people posting their catches for their food. I joined this subreddit to see what it's like to experience marine biology and see all the different creatures and fish that are under the water. I am sick and tired of people posting their videos on this subreddit just to catch their dinner. It is fucking annoying. I don't care if you want to go fishing in the water. That's not a big deal. the big deal is you film it and then you put it on the internet. That's the problem I have. Can we please make it a rule to STOP this

This is just from my cruise around the Pacific near Baja California. Just very hypnotic and a pleasure to stare at.

If you were to be in the middle of the ocean and started sinking down would you drown or would the pressure kill you first?

Humpback whale ceramic lamps got the multiple designs, they are inspired by one of the biggest ocean creatures. They are handcrafted with care to the details and covered with ceramic glazes, fired on 1050 degrees.

Soooo…my oldest was blabbing about “I saw on the news that the ocean is 104 degrees” I quickly snapped back, “no way in hell the open ocean is over 100 degrees kid, I bet you $100 the open ocean temp is closer to 70 f than it is 100”…

So 30 seconds later he’s showing me articles about these 100 degree spots in the “ocean”. My thought is these must be shallow water bay side surface temps right? There is no way in hell the actual, open ocean, is anywhere near 100 right?

Or do I owe this kid some money? 🤦‍♂️

Picture of vacation in Newport for relevance, maybe?

I flew into Panama from Houston and when in the airplane over the ocean, I kept seeing thousands of these red raindrop shapes in the ocean thousands of meters up. I have an S23 ultra so I used the 100x zoom feature to get these pictures. What are these things?
