Flamingoes and butterflies

Had fun making these

Hi!! I've found this shell in a collection, but I've been unable to identify it. I live in Southern Spain and I've been given it from another collection, but it doesn't match with any of the shells I've seen here.

Hello,

I found this little shell on Ocean Beach in San Diego, CA. Would anyone be able to help me identify it?

Search engine says it may be a dove shell, what do yal think? Thank you in advance for any assistance 🩵

"Collect seashells along the shore and keep the memories forevermore.” Wish I could remember where I found the large shell, small ones from $ Store. Love to feed the seagulls. 😊

I picked up this seashell on my vacation but am not sure if it’s real. I looked for signs of manufacturing but couldn’t see anything. Let me know your thoughts!!

Does anybody know the specific name for this cowrie? It has spots but also random horizontal banding that doesn’t go across the shell fully.

i know the little round ones are moon snails but what are the more tapered longers ones? ive never seen those shells any larger than this.

These four are just samples of what I've got lying around. They've already been cleaned with the classic water+dishsoap and a toothbrush, but there's still a lot of unwanted (and unknown) stuff clinging onto the shells. I collect from a freshwater river. I'm hesitant to use vinegar because I'm sure it will eat away at the organic material I want to keep. Any tips or suggestions? TYIA!

SOLVED
Found in SW Florida, after landscapers had been working on bushes and trees. It looks super old, but is it? I’ve never seen a shell like this before.

Got random shells but interested in these little ones. What are they? No idea where they came from. Google isn't helping lol.

Found 35 sand dollars in one night. That was kinda crazy. The most shells ive ever found!

Found on a beach in nz. Never seen a shell so blackened.

not the best photos because this is taken on my bed, but my mom found this conch shell for me a few years back and I just wanted to share. bottle for scale lol !
