Special thanks to Soledad Callo and David Young at Victoria High for the veliger footage that were mistakenly attributed to Dr. Page. Very sorry for the mix up!
thanks to Patreon supporter Sydney Brown for the Pikachu Swiffer line that she left in a comment. Join the community! It's fun!
Hal Brindley:
Hal has an amazing vid of a botfly on his channel... sooooo gross.
Dr. Jeffrey Goddard: Marine Science Institute, UCSB; Midland School
William Goddard: Midland School
Dr. Goddard and his son were very generous with their time and footage! Gave me some great notes so I didn't get my facts bungled!

Dr. Jamie Seymour: Tropical Australian Stinger
Research Unit (TASRU)
Dr. Seymour has captured some of the most remarkable footage of nematocysts firing I have ever seen. Ptowwww.

Bocas Del Toro Research Station

Smithsonian Tropical Research Institute
Thank you to the Smithsonian and to Dr. Maria Pia Miglietta for the wonderful image of the unexploded nematocyst.

Dr. Louise Page :
University of Victoria

Dr. Page's footage of the veligers (Melibe) were a lifesaver. I wish I had more time to spend on their fantastic lifecycle.
Dr. Leslie S Babonis
: Whitney Laboratory for Marine
Dr.Babonis has the coolest job. Firing lasers to trigger nematocyst firing!

Phil Lemley
Phil was so generous to allow me the use of his attacking rainbow nudi...yeah the proctologist...

Dr. Marta Pola Perez
Universidad Autónoma de Madrid

Dr.Perez has looked at the possibility of self fertilization in Nudis - and you never know!

David let me use his Shaun the Sheep slug footage, which is really some of the best footage I have seen of this cute slug.
Pinneng was kind enough to share his Pikachu footage... Quick attack! Electric Shock!
Elyse Messick captured nematocysts firing as a student and I tracked her down on linked in!
Thank you to the following photographers that uploaded their work on Flickr with commercial licenses! A huge help to people like me:

  • If I had had this dude as a science teacher, I might have given up a lucrative career in endocrinology much sooner and "branched" out into stand up comedy.

  • Freaky clay human 😂you’ve done your best.

  • My chromodoris magnifica nudibranch disappeared and I think it died. But I was also thinking it didn't die because no toxins were released in my thing

  • did not expect this voiceover ahaha

  • I choose you Shellos/Gastrodon 😅😆

  • zefrank rap song

  • Nudibranchs? Never heard of it until now

  • "It strikes like a proctologist who lost his wedding ring" I'm dead

  • *exasperated* "and yes that does look like a pikachu that got busy with a swiffer" How often were you told this? That is one of the weirdest sentences I've heard!

  • “Looks like a pikachu got busy with a swiffer” lmao can’t breathe 🤣

  • Are those creatures poisonous? Damn those sea creatures are very toxic and deadly. Not even cute..

  • The snail

  • whenever i see the thumbnail i accidentally think its something from Follow the Leader

  • I got yelled at for laughing too loud at the "why aren't pants pockets shaped like gloves" bit. God I love these videos.

  • 6:46 pretty sure that's a pokemon

  • *Bebbeez...*

  • This is some messed up $#!+

  • I could literally watch all day....

  • “This is the yoga pose they teach you when you arrive in hell” 🤣🤣🤣🤣 sides hurt so much!

  • 4:40 Slurp

  • I'm not able to accept fully that this is real and not a joke SCP

  • You sound like a younger slightly British Morgan freeman

  • bebes

  • there is nothing nudi about them they have beautifull clothes . if i may say so . and even if i wasn't allowed to say so . i would say so . because it is true .

  • Could def see this as a nature show Rick and Morty endulge in from time to time.

  • "They are like a colorblind worker on an M&M factory"

  • Uhh.. Sorry to ask but who counted the Nudibranchs

  • More absorbing with the commentary muted.

  • His voice is like the perfect collaboration of Morgan Freeman & Will Farrell 😂🤣 *NEW SUBSCRIBER/FOREVER FAN* 💯

  • "You'd better stop or I will assault you. This is a dad joke".

  • What are these Shellos doing in my recommended

  • all of these things look like something a child would make up

  • All this series has taught me is that everything pretty in nature is just a complex digestive system

  • I've actually done that yoga pose....

  • i love susie

  • I came here thinking it was going to be somewhat like a BBC documentary... I'm happy I was wrong

  • 7:40 it looks like a lil succulent 🪴🥺

  • Different types of sea bunnies 😂🙌🏻

  • When you tell her less teeth and more tongue suction

  • I learned about these in my biology class, I'm glad they got exposure on this channel.

  • I wish my education was like this...

  • Gastropod torsion was the most disgusting topic I ever felt compelled to research

  • "This is the first yoga pose they teach you when you arrive in hell" I was following his instructions to my discomfort and when he said that I laughed so hard I almost snapped my back in half

  • specifically and by specifically i mean specifically and by and by i mean and by susie. is this man okay?? did he have a stroke?? y’all hear that?

  • 😂😂😂😂😂😂😂😂😂😂😂😂

  • "Ha! You thought it was a cow" Me: *DISAPPOINTED*

  • You are a fabulous narrator - I liked and subscribed immediately after watching this wonderful video 😍

  • Pokemon....just thought I’d leave this here

  • I love these videos - they're super funny, and v educational. I do have a hard time finding the animals sometimes, though - like the 'cuter than puppies' one, which /was/ very cute! I wanted to look up more about it, but I couldn't figure out how to spell its name, which has been a difficulty I've had a few times after watching these videos- the make me want to learn more, but phonetic spelling isn't my strong suit. If there could be a list of the animal names in the description, or in the subtitles, that would be really amazing. Thanks for making these great videos!

  • Wtf is this narration, it's brilliant!

  • “This is the first yoga pose they teach when you arrive in hell” LMFAO WHAT

  • Who else was waiting for the "And that is how the ___________ do" line?

  • Pikachu and a Swifer! LOL! 🤣😂

  • “...this is the 1st yoga pose they teach you when you arrive in Hell.” Scary stuff.

  • These things have some beautiful colors.

  • you had me with: and by "and by" I mean:..... oh yeah...this is how it should be! (montell-voice)

  • "You see these two cows? Tricked you, they are actually nudibranchs." Lol

  • i swear there is no way to not laugh in these videos

  • Hehehe... zfrank1 said "Nudie", without the usual tongue-twisted pronunciation.. .Why, zfrank1? I am disappointed. Are you slipping? Please, say it isn't so.

  • First time iv'e been that amazed yet disgusted. Fascinating...

  • It’s Kos and her children

  • Nature isn't afraid to be fabulous 🥳

  • His voice makes me uncomfy 😂💭

  • a great taxis of animals that most people don't know about. the ocean is full of many wonders we still haven't seen yet. sure, people have heard of sea slugs and snails...but these guys. I suggest you do a video on extremophiles in the ocean vents. those things are so curious! and I actually learned something today!! I had no idea these guys also joined forces with zooxanthellae to feed themselves, just like coral!! super cool

  • All of these things look like a child's drawing brought to life.

  • I just realized, these slugs are the real live version of megaman. Stealing powers to defend themselves

  • You didnt mention that halfway through their lifecycle, some Nudibranchs eat their own brain (true)

  • When you showed "The Old Man Inspecting His Garden" I LAUGHED

  • *"Specifically, and by 'specifically,' I mean 'specifically,' and by 'and by,' I mean 'and by', Suzy is a type of Sea Slug called a Nudibranch."* Said Frank, trying to sound like an insane flute player who's also trying to sound like an exotically alliterative circus midget. And by "circus midget," I mean "swimmy, swimmy time," and by "swimmy, swimmy time," I mean Lion King 1/2, and by "1/2," I mean that *Wreck-It Ralph Wrecks the Internet* sucked butts.

  • Both get to fertilize each other. What a way to an extremely large instant family

  • this is if Blathers was a person You are Blathers

  • You sir are funny!

  • I laughed so much I cried. Loved this! Just subscribed.

  • I actually used this for my zoology class and got an A on my assignment,

  • They are so cute- In a special way-

  • Torsion Ass Sniffing in Hell!!!

  • I now have a new worst nightmare of being eaten by a nudibranch

  • So beautiful

  • I love the speaks in the video, sound like a mix between Monty Python and Terry Pratchett if they were speaks about biology

  • Every time you say "nudibranchs" it sounds like "nudey branchs" and it makes me giggle.

  • I saw a shellos on the thumbnail, clicked and then watched an entire video on some regional variants. endcaten

  • ''This is the first yoga pose they teach you when you arrive in hell.''

  • 😍😍😍

  • zefrank1: Nudibranchs CC: Nuter pranks? Neuter Brinks? Nut D pranks?

  • So you put a sculk sensor for the thumbnail

  • Un- coupling is a bitch but but they know how to party

  • So are we not gonna talk about how he said claymation pubic hair?

  • I miss the overly-exaggerated pronunciations 😢

  • The one on the thumbnail looks like a shellos

  • I love this video

  • HE'S BACK !!!

  • Best narrator ever always has me laughing ❤️🇬🇧

  • Let's call it a NakedStick! (Guy who has above average literacy) I have a thought...

  • Ze Frank hitting us with the unsolicited nudes... But we are all glad to see them

  • The dialogue is idiotic.

  • Anyone on schoology ?

  • So I can’t eat it?

  • It's Gastrodon
