Thanks. Had doubts on my pear ID.
This shell has so much going on!!! What a fantastic find! We’ve got the Strombus alatus (Florida Fighting Conch), 3 tiny Melongena corona (American Crown Conch), beautiful webs of Bryozoans, Serpulidae (Serpulid Tubeworms), some new & exciting Spirorbis (Spiral Fanworms), inside are Crepidula (Typical Slippersnail), outside are Crassostrea virginica (Eastern Oyster) & the largest current occupant is the Clibanarius vittatus (Thinstripe Hermit Crab).
I’m wondering how long it took for this “community” to form.
