Rating: 4.0; Vote: 1
Today we're (finally) going to talk about animal babies! But more than just puppies and piglets we're going to be looking at their genes. Sexual reproduction is part of the very definition of what it means to be an animal and as you'll see life has found a variety of methods to pass down genetic information. We'll also discuss the differences between sex and gender, take a closer look at sex determination systems, examine how same-sex behavior happens all across the animal kingdom, and live a day-in-the-life of the serially hermaphroditic clownfish!

TIMESTAMPS FOR SPIDERS/ARACHNIDS-
0: 55 -> 1: 02 Several, animated (intro)-
8: 50 -> 9: 06 One, animated (tarantula, or some other mygalomorph)
9: 25 -> 9: 26 One, real (peacock spider)
As a spider scientist (and the science consultant for CCZoo, I love these wonderful animals, but I realize that being startled by a spider can be scary (even if you like them. An important part of overcoming arachnophobia is building positive interactions with arachnids on /your/ terms, so hopefully this helps some of y'all do so and enjoy the videos.

Rofl!
reproduction
not that difficult
and still we disconnect
it is as simple as can be and in plain view to discover.
No certification required just know man should work in kinship with Nature
it is a Law after all.
Not hard to see if you know where to look.

This is so cool!
Another interesting species is the Sonoran whiptail, which are all genetically identical females. Even though they just clone themselves, though, they need to engage in mating-like behaviors with other Sonoran whiptails to stimulate the production of the clones.

2: 18 More context needed, and I couldn't find supporting information for this statement. If true, why do I suspect that the bulk of this secret majority of species that don't/never reproduce in a binary, also happen to be imperceptible to the human eye?

I think this is a very speciest video. how do we know non-human species don't have genders too? You're denying the identity of all the transgender non-human animals out there. Shame on PBS for spreading such hatred and transphobia!

My daddy said it was when a mommy bee - has 80, 000 other daddy bees who love her work there whole life to please the mommy bee & don-t get anything out of it in the end & that-s how I-m here & that-s life

--Finding Nemo would-ve been a very different movie if it was 100% scientifically accurate--
Think about that for a second-
Now you feel my suffering --

reply

Concerns for sea turtles and global warming is influencing reproductive cycles since temperature determines which gender the eggs become.

What I learned from all this is that the dad in Finding Nemo would actually become the mom and the son would become the new dad.
