Does he take some form of sedation therapy before narrating the videos? He usually has a very boisterous voice.

[@SLAUGHTEREDEYES]

This footage is mind nunbingly clear and sharp. The scope alone is amazing but the recording camera is impeccable as well. Please dont ever stop making vids!

[@frankievalentine6112]

Yeah! We hear so much about the microscopes, but what do y'all use to record it with exactly??

[@NoenMar]

It's freaky to see the black "pupil" that absorbs all light in and ao has no reflection. Kind of like a miniature black hole

[@selfworm]

Water at this small scale really is more like syrup.

[@trustthedogsheneverlies644]

@@Pixel_scribes Relevent here it describes the impact of viscose forces of flow for a specific reference and given that these guys are so small they can never escape the laminar world. This drastically defined how they (fly) through the medium and allows for much simpler geometry for propulsion. In fact at rest Re is irrelevant but it's fascinating to see what such flows alow for 'designs' of propulsion.

[@jacobv3396]

Love watching these videos right before bed. Puts me in a relaxed mood.

[@vapormissile]

Yep. Aquatic ambiance, soothing voice, cool science words, reassurance that it's okay to be odd, wiggly & exposed.

[@zacharywong483]

Bravo once again to James for finding such cool specimens and for getting such pristine footage! Awesome video!

[@ceruelion815]

It's wild how in closeup, their eyes bear a striking ressemblance to our own.

[@amberwalsh5767]

Love listening to you Hank, your voice in this channel. Felt it was very relaxing

[@benjaminwagner4702]

I’m so thankful for this show and the team that’s behind it and the families behind that team. Peace and wellbeing. Thank you for bringing the most educational and informative videos on the microcosmos

[@Lava_Girl-]

I love this channel so much.

[@AHIDDENWORLDmicrobiology]

So nice. You are an example when it comes to microbe-related stuff.

[@stephanieparker1250]

Amazing footage! Well done, James!

[@JamsGerms]

Thank you!

[@freehat2722]

Is it possible to get the whole microorganism in the view and in focus with the camera? Without having to take multiple images?

[@fallenasleep7247]

How do we know we aren’t just blinding leptodora by shining a super bright light through them?

[@jajwarehouse1]

That was my thought, as well.

[@hamjudo]

Seems likely. This creature only hunts at night. It put a whole lot of resources into growing its huge eye. Eyes are complex and "expensive". If a breeding population adapts to living in a cave it won't take many generations to lose eyesight. If I understood the description correctly, this water flea has 500 light sensitive cones. That is enough to form images and to identify motion. The eyes have to be good for something significant in their native habitat. Finding food, avoiding becoming food, or mate selection.

[@Synthetic_geth]

We probably are

[@cerberaodollam]

My sleep deprived brain: 🎶 "L-l-l-leptodora!"

[@ira6133]

I can't get over how these tiny microscopic creatures don't nearly look like anything we see on the land. They look like aliens.

[@limiv5272]

They'd probably say the same about you if they could see you

[@ira6133]

[@AphidKirby]

YESSS Leptodora are such bizarre organisms I love their messed up body plan! Great video!! Hopefully one day you'll get to highlight Cercopagis! Another bizarre Cladoceran predator!

[@supreetsahu1964]

the black thing with red eyes from 1:31 to 1:35 that looks like it's motion is captured at 4 fps is hella creepy

[@bradyb2884]

its prob a cyclops

[@Rudol_Zeppili]

That’s a Copepod, they move like that because at those scales it’s harder to push water with that surface area, so they flick their antennae to move through the water in a really fast movement and then they lose momentum to the water, and then they flick again. If you have a pond or stream nearby you can find them and look at them do it, don’t even need a microscope if your eyes are good enough. (You won’t see their antennae just with your eyes though)

[@bradyb2884]

@@Rudol_Zeppili Quick Question, I seen people use the terms Copepod and Cyclops interchangeably is that correct?

[@Rudol_Zeppili]

@@bradyb2884 Yeah, copepod is just the scientific name for it, so the search engines would know that someone is searching specifically for the animal.

[@wuhteva9805]

That was the closest this channel has ever gotten to hitting me with a jump-scare, lol This video really pops, ultra sharp and colorful.

[@bigbrady2244]

good mix of footage

[@christinakinch]

Thank you for the video.

[@N1RKW]

I find myself wondering if the body cavity is as open inside as it appears on this video. It looks to me that the creature's carapace is much larger than it appears to require.

[@zddxddyddw]

Remember that it is filled with blood, muscles, nerves and other tissues needed to keep those visible organs alive.

[@Fadel-wj9wk]

Thank you#

[@TedToal_TedToal]

So what made it actually use its eye for? Is it possible it uses it only under very low light conditions?

[@Twin-jl1bi]

Best episode in a long time

[@Guydude777]

Good spooky vibes

[@Dzdzovnica]

when you hear city you live in (Warsaw) in a video like this you start looking different at bodies of water around you

[@JamsGerms]

If you look around the water bodies you may see a James one day!

[@NibblyBitz]

What is the pulsing thing (heart???)

[@mkl80]

Fascinating

[@NewMessage]

Some take the term 'shrimp' farther than others.

[@TheFanOrTheMask]

its weird to see its little heart beating

[@brendakrieger7000]

Fascinating🔬

[@AtillaTheFun1337]

They look like they have great trouble swimming. Not unlike how all those dang crane flies bumble around flying as gracefully as tumbleweeds.

[@Jumptownwore]

Maybe the light in the microscope blinds it?

[@DracarmenWinterspring]

Is it a reasonable guess that the ancestor of these guys and other crustaceans looked more like the macroscopic crustaceans, with two eyes? I'm curious how a change as drastic as having 2 eyes turn into one in the middle and right at the tip of its head happens (might be easier if they don't actually use that eye as a primary sense)

[@nunjahBitnes]

Swims around and any flow resistance to its hairs would signify that something is nearby. What is hair sensitivity too.why is that dark patch so dark

[@stax6092]

[@sirave6017]

Centimeter long? I think you meant millimeter long. The scale bar depicted when speaking of the size shows 400 micrometers and is around half the length of the water flea.

[@JamsGerms]

It's hard to film large individuals so we used smaller ones. -James

Maybe it needs to be super upclose

[@TearyEyesAnderson]

The Daphnia family is rather interesting for another reason. It is also related to the Scooby, and Shaggy families. But just how they are related is a Mystery to science, which some specialists think is a bit Spooky how they can sometime disguise themselves to look like one another.... ;)
