Dwarf Triton
Cymatium (Turritriton) comptum (A. Adams, 1855)
I have two excellent Dwarf Tritons in my Collection so far. Both were collected in December 2020 on S. Hutchinson Island (the images below are slightly enlarged).
Dwarf Triton (about .75" from S. Hutchinson Island, December 2020)
2nd Dwarf Triton (about .5" from S. Hutchinson Island, December 2020)
