Incredible finds! Wow! We find some similar shells in North Carolina but call them different names. No volutes, strombus or murex with long tails. They do have a carrots murex in SW Florida though. At about 8:10, we’d call that a cardita. At about 9:12, a cross barred Venus clam. The pectins you are finding are similar looking to our lion’s paws. We treasure those!!
