squid cuttlefish shell

this squid shell is a rare thing and only this is the only one type of squid squid that has a shell

the first time I see this shell I think this shell is just an ordinary shell that attracts me only to its large size.

after I take it home I save and a few days later I see a video in electronic media about ancient animals that shell just like I brought home this.

and it turns out this shell that I brought home is not the property of shellfish or crab, but the owner is squid squid. and this squid-shaped squid is a rare star and also includes an ancient animal.

I am very curious about this animal whether this animal is still living in the aceh ocean or just the shell that is brought to the ocean waves aceh.

location I found it in North West Hagu Village, Lhokseumawe City, Aceh, Indonesia.
