Do the sharks have names? My gf loves the sharks, her favorite is the nurse shark and mine are maybe the epaulette sharks

Some sharks do! There's really no rhyme or reason for naming/not naming a shark, but here are a few sharks with names.

This is Nandor the zebra shark

This is Fern the zebra shark

and this is Sam the leopard shark. His name is Sam because his spots spell "I AM"

This was posted to a peafowl group a friend of mine is in; it's a comparison between a European violet (front) and a European violet x US purple cross (back).

EVERY other color mutation, when bred to a non-same mutation, produces wild type coloration cocks. The sex-linked genes produce mutant hens, but not cocks. The birds have to be the same mutation in order to show any non-wild coloration.

The cross bird doesn't look like a purple; it's too red. It doesn't look like a violet; it's too blue. Which tells us that EV is either an allele to purple that co-expresses, or it's the same gene with different epigenetic markers that give it a different phenotype to US purple. We already know that purple mutated twice here (once in wild type stock, once in cameo stock), and they have a HUGE range of variation in how that expresses in the phenotype. We also know that when purple expresses with the bronze mutation, it results in two VERY different phenotype mutations- hazel and indigo. When hazel is bred to hazel, it produces hazel and indigo, and vice versa, with no discernible pattern to it.

I don't know which it will turn out to be. My guess is an allele. I hope that I live long enough to see the genotype mapped and the mutated genes IDed and published, so I can find out.

Cuttlefish can change color to fade into the background. It can do it amazingly fast.

Bird of the Week: The Kori Bustard! 🪶

I just wanna yap about these guys I really love them.

The kori bustard (Ardeotis kori), is the heaviest flying bird, with adult males weighing anywhere between 25-42 lbs. However, they tend to spend most of their lives on land.

While emitting a deep booming call, males will puff up their neck plums and tail feathers for a mating display.

They are native to grasslands, savannas, and wooded areas throughout southern Africa.

These beasts are omnivorous, with diets made up of insects, reptiles, small mammals, small birds, and plant matter such as seeds and berries.

thoughts on polyamory?

thanks for asking! first of all, I think love is weakness by another name and you should be killing everyone with your demon blade

You're the healer of the group. The rest of the party has always treated you like you're made of glass. You were content to stay out of their way and let them do their thing. Until they all got downed leaving you the only one standing. That's when you show them how deadly healing magic can be.

The diagram for the classic Origami Goat, with a twist to make its horns curve ! It's from this video by by Origami Word, but it seems to be a pretty old/intemporal design that a lot of people have made. I could not find a diagram online so I made one.

(If you make her in yellow/orangy-yellow, then decorate her with red ribbons, you can make your own origami gävlebocken ! )
