Barnacles | In The Field

We’re in the field examining barnacles, which make up the class Cirripedia. There are over twelve thousand species of barnacles, most of which live intertidally attached to hard substrates. When the tide is out they close their calcareous shell to prevent desiccation, and when the tide comes in they extend their cirri to feed. There are two groups of barnacles the acorn barnacles and the goose barnacles. The most common is the acorn barnacles which can grow in dense concentrations such as the common rock barnacle Semibalanus balanoides. One fascinating thing about barnacles is how they reproduce. They are hermaphroditic with fertilization taking place through a penis that can be up to twenty times the length the barnacle’s body!

She talked about genitalia without feigning the whole "I have to call this gross" nonsense. Respect.

An absolute menace! The scourge of the sea and to any boat owner.

I bought my dad a 6m fishing boat for his 60th birthday. Once we took it to the sea and after ONE outing, there were a few barnacles on there!
Nasty, sharp things that can cut your leg in the sea, a drag to ships, increasing fuel consumption and a huge deadweight for turtles.

Thank you for the proper and scientific use of all words as well as smiling at the start of the vid, it really is contagious!

I love them, I have some growing on the glass of my 55 gallon. The ones that attach to rocks are fascinating, I don’t really like the species that attach to animals.

Why does she sound like the female version of Chills??

[RikkieMc]

I randomly questioned what barnacles were and this video answered all the questions i had. Thank you and great job

[iamsivadath]

[kiarashtamizkar]

[gabiquinn]

This was the video I have been waiting for

[rorymaclean]

great information, diction could use some work though.

[presidenttogekiss]

Wow, I always tought barnacles were moluscs or worms, not arthropods. Living and learning.

[Ashishg]

Her voice reminds me of Chef John from Food Wishes.

[annakeenan]

[gautigautam]

Why is everyone hating on her voice?It's pretty good and understandable and she could convey the necessary info.

[QueenOfArabianSea]

Very nice. I taught my daughter what barnacles are. Thank you

[alhemednasser]

It is great details on macro organisms . It would be better to set some advantages and disadvantages of these organisms

[FPSIreland]

These things are so cool but they freak me the fuck out with all the little holes ahhh

Edit: the fact that they're crustaceans absolutely blows my mind... like wtf does the common ancestor of a barnacle and a crab look like? Questions, questions, questions...

[theidknetworkowo]

I found snails growing out of them at the beach and me, my friend, and her little brother made homes for them
