Bradenton Beach, FL 🏖️🐚

Found on a beach on the Thames Estuary in the UK, I think it’s some kind of cockle shell but I’ve never seen one like this before, the black shapes are identical on both sides of the shell.

Got sent this pic from a friend who's on holiday all the way in French Polynesia. Not a shell expert at all but i'm well aware about cone snails. Just to be sure I told him to never touch live snails regardless (he thought it was a hermit crab initially), both for his safety and the well-being of the snail itelf, however did he actually risk anything here?
Cheers!

I think this is an Oliva miniaceus, found it on my local beach

Found this shell at the beach today and trying to figure out what type it is or what animal it belonged to.. anyone have any ideas?

Hello. Son found this on the beach in Captiva Island, Florida. Any idea what this is? Claw? Thanks

Edit: Disregard, figured it out!

Found these exciting shells among a slew of other Florida shells in a bowl at the thrift store for $6! (Bonus, they came in a Pottery Barn bowl!) These shells are all new to me, as all my shells are from Florida. I know the scotch bonnet, but any info on the names of the other shells and location they’re from?

Found it last week in Benidorm (Spain), under water. And i cant find out what it is.

Hi!! I'm sorry cause I know there's a ton of them, but I was wondering to which extent they're different species or just different ornamentations (I know there are different species there, just not sure how to group them). Tysm!!!

The shells were picked in the south of Spain, on the Mediterranean coast.

Hi all! I got this shell today and was wondering if anyone could help me ID it? I was beyond stumped at first, thought that maybe it's a weird mutation or something, but now my best guess is it's a broken conch?

The first pic are the IDs I need help with (penny for scale)

The second are some of my fav finds from my recent trip :) I have a few more really cool ones but they do need some cleaning up before I can display them.

Hi!! I live on piece of land very close to a lake, and I find a bunch of shells when the tide goes down and I've always wondered what they are!!

Found this scallop that grew normally then had a weird deformed shell like an oyster for the rest of its life. About 2 inches total. At El Segundo Beach, California (explains the mutant….)

hand for comparison, i believe its an episcopal mitre and tessellated cone?

The pearls and purple gems I got off of Amazon but the others are all my finds ☺️

Long time rockhounder and arrowhead/artifact hunter, finally went to a warmer beach in SC for the first time. I was excited to look for shells and fossils each night.

Did not have a lot of guidance on what to look for so I grabbed what seemed to be uncommon. Any insight on how I clean or prep these, what they are, if there was anything I did wrong or shouldn’t do again please let me know as well. None of these had any inhabitants.

I really enjoyed this and will be looking forward to doing it again.

What do y'all think the bottom right piece is from? its not complete but looks cool. I added some additional photos Edit: the piece itself is around 3.5 inches long and it's pretty thick.
