I need help identifying these shells

[endofallhope]

Hello,
1. Cymbiola vespertilio, Bat Volute
2. Murex trapa, Rare-Spined Murex or Trapa Murex
3,5  These are juvenile specimens in the Conch family (Strombidae).  Adult shells in this family are easy to identify, but juvenile shells, lacking most of the adult features, tend to look very much alike.  Not certain, but I believe these are juveniles of the common Spider Conch, Lambis lambis.
4. Strombus turturella
6. Babylonia areolata, Spotted Babylon or Areolar Babylon
7. Angaria delphinus, Common Dolphin Shell or Common Delphinula
8. This is a member of the family Trochidae, commonly called a Top Shell.  It is quite eroded, with the pearly underlayer showing through, and most of the color and pattern gone, so I'm not sure of the species.  Based on general shape and what sculpture is left, it could be Tectus pyramis.  But I am not sure.

All of these are from the tropical Indo-Pacific region (S.W. Pacific and Indian Oceans).
