Not that my blog is exactly cetacean-exclusive, but with all the drama I’ve been seeing on my dash lately, expect it to be even less about cetaceans.

I just made a new blog which can be found here. It will be focused on toothed whales and I plan to keep it entirely neutral. No captivity debates, just photos and videos of beautiful toothed whales in both wild and captive environments :)

So if you guys want to see cetacean stuff without having to worry about debates, feel free to give that blog a follow! There’s absolutely nothing on it yet, but I plan to get it set up over the next week. Thank you in advance if you decide to follow :D

With my biology background, I’m surprised I didn’t realize this sooner…

If Nalani were to give birth to a calf, assuming she’s not related to the father of her calf, the offspring wouldn’t be affected by inbreeding at all.

You receive half of your chromosomes from your mom and half from your dad. Because Nalani and her father were both Katina’s calves, Nalani likely has a few pairs of chromosomes that are identical to each other. This is when inbreeding becomes a problem, because harmful, recessive genes are more likely to be expressed when two chromosomes are exactly the same.

However, if she mated with an unrelated male, she would only pass down one set of chromosomes to her offspring, not both. If Nalani has a pair of chromosomes in her cells that contain harmful recessive genes due to inbreeding, it wouldn’t affect the calf because it wouldn’t be getting both pairs of chromosomes from her.

So, if Nalani becomes pregnant at any point in the future, I don’t want to see people complaining about the calf being inbred, lol (unless, of course, the father of the calf is related to Nalani.) And this goes for Adan and Keijo as well, if they ever have offspring.

I’m a bit confused, maybe I’m just not understanding something here. The chromosomes an individual passes down to their offspring are most likely a mix of the father and the mother’s, right? It’s not like we only inherit our grandfather or our grandmother’s DNA, if that were the case we could technically be genetic siblings with our uncles/ aunts. So isn’t it the overwhelming possibility that Nalani’s calf will inherit identical genes from both Taku and Katina? 

That being said I don’t believe this level of inbreeding in this situation is cause for major concern. Should Nalani breed with an unrelated male, chances are the calf will be perfectly healthy. 

Well not quite. Inbreeding can only occur if the two individuals are actually related. If two individuals are inbred, but un-related, the offspring are indeed not inbred. Granted the more inbred something is the greater the chance of them having reproductive issues that give them a hard time is. For instance, Giant otters used to be extremely in-bred in captivty (to the point where no pups were surviving more than a few days past birth), and once fresh animals were imported, those once failing animals started to produce healthy, vivacious pups.

Or if you want, you can refer to this coefficient of inbreeding chart, which shows that even if Nalani bred with Keijo, the calf would still be a healthy outcrossed animal with a 0% COI

So inbreeding is a factor that lasts only one generation so long as the inbred individual’s mate isn’t related to him/her? 

I drew up a nifty little chart show show what I mean, haha.

Say you have three pairs of chromosomes in your cells. The left pair (1) is from your mom, the right (2) is from your dad.

Katina and Tilikum are Taku’s parents. Taku gets half of his chromosomes from his mom and half from his dad, as you can tell by the colors. None of the chromosomes are identical pairs because his parents are not related to each other.

Then take Nalani. Taku mate with his own mother to produce Nalani. Because Taku had some of the same chromosomes as his mother, Nalani ended up receiving some duplicate pairs of chromosomes purely by chance. This is when inbreeding is a problem, because there’s less genetic diversity within that individual, making them susceptible to illness or genetic diseases.

Then take a random male that could mate with Nalani. He is not related to her, so none of their chromosomes are identical. They mate, and the calf receives half of its chromosomes from Nalani, half from dad. Because Nalani only passes down ONE chromosome from each pair, not BOTH chromosomes, the calf doesn’t have any pairs that are identical, thus, inbreeding does not effect the calf.

I hope that cleared things up!

And yes, if Nalani mated with a male that was, say, her uncle, THEN her calf would be inbred, because Nalani and her uncle would share identical chromosomes. If the father of the baby was unrelated to Nalani, however, my diagram would hold true :)

There are so many dinosaurs that are totally badass but then there’s the cotylorhynchus.

Look at this fucking asshole with its tiny-ass head.

and yes, it’s real: http://en.wikipedia.org/wiki/Cotylorhynchus

Not a dinosaur, but a synapsid. More closely related to mammals than anything else. Still pretty goofy looking though :)

Dear those who support SeaWorld c:

mulder-andscully:

I’ve written 11 questions to you guys because I’m honestly very curious as to what your answers are. I personally am anti-captivity but am really open to seeing what those who are pro-captivity think about SeaWorld. Please feel free to reblog with your answers :)

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

1: Everyone says SeaWorld doesn’t capture whales anymore, but it doesn’t change the fact that they still possess captured whales in their collection (Corky 2, Katina, Kasatka, Ulises, & Tilikum). The deceased captured whales in their collection were Shamu, Kandu, Kilroy, Ramu, Orky 2, Nootka, Ramu, Kandu 3, Kona, Canuck, Sandy, Frankie, Kanduke, Kenau, Gudrun, Canuck 2, Kona 2, Kandu 5, Winnie, Shawn, Kahana, Kotar, Bjossa, Haida 2, Nootka 4, & Samoa. So, they’ve captued 31 whales in all. Do you guys support this? Do you support them still keeping these whales, and, if so, why?

2: Nalani, one of their current whales at SeaWorld Orlando, is the result of inbreeding between son Taku (now deceased) and mother Katina. Do you think this is right? Do you support SeaWorld Orlando for breeding mother and son? If so, why?

3: The majority of whales in the wild don’t leave their family pods upon maturity, yet SeaWorld constantly separates mother whales and their children. For example, Kalina and 5 of her 7 calves have been separated, all of Kalina’s calves had been separated from her, etc. Do you guys support this? If so, why?

4: The environment that the whales reside in at SeaWorld does not, in any way, resemble their natural habitat. There’s a pronounced lack of stimuli, lack of real food, etc. Do you support this? If so, why?

5: Do you think SeaWorld’s shows are educational? As in they educate the public further about the animals, promote conserving the species, etc. If so, how?

6: Keiko’s release is constantly cited as a failure, despite him living for 6 years in his natural environment and dying from the same ailment that has killed many captive whales, such as Taku. Do you think Keiko’s release was a failure, and, if so, why?

7: SeaWorld is constantly breeding their orcas, despite the massive amount of complications in the breeding program. For example, Baby Shamu 2 lived for 11 days after birth, Haida 2’s calf lived for 38 days after birth, there have been 14 stillbirths/miscarriages at SeaWorld, Gudrun, Nootka 4, Samoa, & Taima all died during labor, etc. Do you support the breeding program? If so, why?

8: The life spans of killer whales in captivity are greatly shorter than their wild counterparts. Do you think, in terms of how long the animals live, SeaWorld is beneficial to them (in comparison to the wild)? If so, why?

9: One of the biggest arguments supporting SeaWorld is that it teaches children about killer whales. Do you think that, without SeaWorld, it’s possible for children to learn about whales? Books, television shows, movies, etc. Is SeaWorld the only way of learning about whales? If so, why?

10: There’s a lot of aggression in both the wild and captivity, yet in the wild, there are no walls forcing the whales to be in each other’s space. In SeaWorld, the whales are crammed into pools that are much smaller than their natural habitat. Do you support the size of their pools? If so, why?

11: If you support SeaWorld, then please explain why? And, if so, are your reasons in the animals’ best interest or in the best interest of humans?

Just wanna respond to number 2 real quick, I’m pretty sure Katina’s pregnancy by her son wasn’t an intentional breeding on SeaWorld’s part, but I’d have to find a source to verify that.

theres a giant burning orb in the sky and it can burn your flesh, it can give you diseases, it can kill you, looking directly at it causes physical pain, and we all think this is okay. we like this orb.  we like to go outside and lie around on our backs when this orb is in the sky. children draw cute pictures of this levitating death orb with a smiley face on it. what is wrong with us

I don’t normally post about my personal life much on here but I just can’t get over how excited I still am about this

I went to a Fall Out Boy/Paramore concert last night with my roommate and it was amazing.

AMAZING

This is Kshamenk.
During this show, he was asked to this one and only trick, touching his nose onto the ball. After he did his one trick, he was sent away to his hellhole. He is the loneliest orca I know of, along with Lolita. He has no companion and he is sexually frustrated. I don’t know much but I think he tries to mate with one of the bottlenose dolphins. When he is not performing, he is seen in his little tiny circular tank. Orcas do not do well in circular tanks, nevertheless being in a crappy, small tank.
Surprisingly, for a captive Male Orca, Kshamenk has a good look to his tail flukes. They don’t curl. But it is suggested that he is underweight.
SeaWorld does business with this place. Where do you think SeaWorld got the sperm to create little miss Kamea?
If you support SeaWorld, you are helping this place thrive. Please, Don’t buy a ticket.
Captivity Kills.

He also fathered Makani, which makes Makani and Kamea siblings and uncle/niece.

Tails develope curling in the wild too, though? I’ve seen it on a lot of individuals photographed from different pods around the world, most always in males. Is this not something that is typical or?

they do, yes. but i don’t think that is natural. please don’t attack me for any reason, its late for me and its hard to think right now. i will look more into the subject tomorrow or when i get a chance. but naturally, i think tails aren’t supposed to curl.

The flukes of adult male orcas usually curl, both in the wild and in captivity. This post said Kshamenk’s flukes don’t curl, which isn’t normal for an adult male of his size (though I can’t be sure if that’s a sign he’s underweight or if he’s just different. Anyone know Kshamenk’s length and how much he weighs? lol)

IS THAT ULISES I SEE?

yes it tis. :D
how’d you know? Lol

His dorsal is so distinct from the rest of the captive males, hehe. These look awesome so far, by the way! Sculptures are pretty tricky to get the hang of.

I want to ride a roller coaster so badly. I haven’t in years, and I can’t here in Florida because it would seem every theme park decides to hold dolphins and other animals and I don’t approve of their standard of care. I heard the animals at Busch gardens were…

Yessss universal is the only place I think I want to go but I just wasn’t sure about the animal thing. Thanks!!

No problem! Universal is pretty great :) but you might want to double check the captive animal thing just in case. I didn’t explore every square inch of the park so I could have missed something, but I’m pretty sure they don’t have any captive animals there!

I heard the animals at Busch gardens were constantly pacing and looked malnourished. Go figure?

Edit: not that I would go there as it’s owned by Seaworld I’m just sayin

What about Universal Studios? I don’t recall there being captive animals there at all… But if they do have them, I know for a fact they don’t have cetaceans.
