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.

more importantly they’re walkin on little peets

That’s a unique and special characteristic of only these particular cuttlefish! Look at how they use two flaps of tissue like “hind legs,” with little protrusions that even act like TOES! No other cephalopod has those at all, and no other cuttlefish use their outer arms like front legs, either!

These are cephalopods evolving into “quadrupeds!!”

They do this to conserve swimming energy while they hunt, which has worked out so well for them they’re pretty poor swimmers, like a bird on its way to flightlessness.

The stripes flowing down their skin make it difficult for their prey to discern which way they’re walking or how fast. Then the “flamboyant cuttlefish” gets close enough to shoot out the two specialized arms cuttlefish use like a chameleon’s tongue 😀

little peets for maximum efficiency stalking and killing :)

And I know what some of you may be thinking: “a slow-moving, highly conspicuous little guy just trotting along on the seafloor? How come they don’t just get eaten to death?”

It’s because they’re incredibly, horrifically toxic! Poisonous as shit! Just a buncha lackadaisical, impeccably dressed little fellers made of pure mutually-assured destruction! ☺️☺️☺️

it’s also important to note that they are just

REAL FUCKIN SMALL

and this also makes them easy for larger predators that are more resistant to poisons to miss down there on the seafloor

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.
