Did You Know! Elephant Seals Are Negatively Buoyant, Which Means That They Sink Naturally In The Water,

Did you know! Elephant Seals are negatively buoyant, which means that they sink naturally in the water, but have to use energy to swim back up. This means that they are able to save 18-24% of their energy on a dive compared to having to actively swim down. This descent is so effective that they can actually fall asleep on the way down! They are also officially described as "falling like a leaf". Have a look at the cool diagram below that I pulled from one of my university lectures that I went to a few years ago.

Did You Know! Elephant Seals Are Negatively Buoyant, Which Means That They Sink Naturally In The Water,

ID: a diagram of the descent pattern of an elephant seal. There are three axes (depth, distance west and distance south) showing the distances from the release point in metres. There is a coloured scale showing the speed of the descent, and a spiral made up of coloured dots that show the route.

I am obsessed with this whole aesthetic thing people have going with college studying, most especially with STEM. It's so foreign to me because I don't know about anyone else but when I studied for exams my work space looked like someone had ripped apart a book and thrown pages in all directions.

[Cueball and Beret Guy walk up a grassy hill.]

[They continue and reach the summit.]
Beret Guy: I learned something today.
Beret Guy: I went on one of those family tree sites and kept clicking back, and it turns out I'm related to stromatolites!

Cueball: The bacterial mats?
Beret Guy: Yeah! A few billion years back, on my mitochondria's side.

Beret Guy: My Archaean ancestors absorbed some bacteria that were cousins of stromatolites. That's how I got mitochondria.
Cell nuclei, too.

Cueball: I think there are still living stromatolites. You could get in touch.
Beret Guy: Nah, they're probably busy. I don't want to bother them. 

Cueball: So what are you going to do with this knowledge? Nothing?
Beret Guy: Lying on a hill in the warm sun is an old family tradition.

If only my ancestors had been fortunate enough to marry into the branch of the bacteria family that could photosynthesize, like all my little green cousins here.

Stromatolites [Explained]

Transcript Under the Cut

[Cueball and Beret Guy, seen from a far in silhouette are walking up a grassy hill.]

[They continue walking up the hill, reaching its grassy summit. Now with a standard white background. Beret Guy is a bit ahead of Cueball.] Beret Guy: I learned something today. Beret Guy: I went on one of those family tree sites and kept clicking back, and it turns out I'm related to stromatolites!

[Closeup on Cueball. Beret Guy's reply comes off-panel from a starburst on the right edge of the panel.] Cueball: The bacterial mats? Beret Guy [off-panel]: Yeah! A few billion years back, on my mitochondria's side.

[Cueball and Beret Guy standing on the top of the grassy hill facing each other. Berety Guy holding a hand out towards Cueball.] Beret Guy: My Archaean ancestors absorbed some bacteria that were cousins of stromatolites. That's how I got mitochondria. Beret Guy: Cell nuclei, too.

[Cueball is standing behind Beret Guy who is now sitting down in the grass leaning back on one arm with the other arm resting on his bend knee.] Cueball: I think there are still living stromatolites. You could get in touch. Beret Guy: Nah, they're probably busy. I don't want to bother them.

[Cueball is sitting behind Beret Guy who is now lying down, both again shown in silhouette from a far, revealing they are on the top of the grassy hill.] Cueball: So what are you going to do with this knowledge? Nothing? Beret Guy: Lying on a hill in the warm sun is an old family tradition.
