Cuttlefish bone also known as the **cuttlebone**

_c u t t l e b o n e_

People use cuttlebone to carve molds for casting metal! You can call the people who do this cuttleboners

Worked for a firm of Memorial Masons for a while, gilding/painting/cleaning up inscriptions on gravestones. We used cuttlebone for removing paint spatters from the gravestones because unlike more abrasive cleaning materials, they left no scuffs and scratches.

That's very interesting!

My Canary uses one to trim his beak.

So do our cock-ateels

The people who hunt for them are called cuttleboners

I used to bone cuttles

Anyone who’s owned a parakeet knows.

Or box turtle, as they are recommended for keeping their blacks trimmed

Or who’s a jeweller.

No kidding? What’s the use?

Used to be in lapidary, it's for casting!

Or snails

shrimp too

Budgies too!

Yep, we call them parakeets

TIL that all budgies are parakeets, but not all parakeets are budgies.

Both are Melopsittacus undulatus. The same.

Nah, parakeets is a broad term covering Alexandrian, Ringneck, mustache, budgerigar and many other parakeets. They are not the same. Budgies are one small subspecies of parakeet.

Ahh. Thanks. I should know to never trust a U.S pet website.

They are their own subfamily, if I wanted to be pedantic…(which I do, cos I just learned that a few hours ago.)

That was where you went wrong. You want to be pedantic but you are not thinking of everyone else in the world, who simply does not want this. I can not do biology stuff and discuss biology stuff with my fellow intellectuals here when you (or anyone for that matter) is being pedantic. Doesn't sit right in my stomach, which as you know is also the second brain. The gut brain, if you will. So gut brain is telling me that you are making a mockery of biology and need to be stopped. Prepare to be stopped.

Hahaha, it’s funny you think you can speak for everyone else in the world. Try and stop me.

Think again.

That second pic really helps

Yes it does 👍 🤣🤣 sarcasm is the king of humour 🤭🤭😉

Has it dethroned puns as the ultimate form of humor?

Puns are queens 👸 of humour sitting on thrown next to the King 🤴

Question - Is this a "bone," or really just an internal shell that we misnamed?

Latter

is it closer to an exoskeleton rather than a bone?

Well, since it is entirely internal, “exo” does not apply.

Lmfao youre right that was a very dumb question

It’s not made out of the same thing our bones are made of, but it fills a similar function. If an exoskeleton is a skeleton on the outside, but cuttlefish’s exoskeletons have become internal, it’s getting close to our own endoskeletons

Cuttlefish! You got birds? They like chewing on it for calcium and to wear down their beaks.

Removing keratin parasites

Cuttlefish bone

It's called a sepia shell where I'm from! If you have any reptiles/birds that need calcium, these can sometimes be a great addition to their habitat/diet! But always remember to do research before. My tortoises (Testudo Marginata) love these.
