Argonaut molluscs (A family in the Class Cephalopoda)
have only vestigial shells, but their egg cases on the other hand, are
justifiably famous!! Once a year, the female Argonauta carefully places
all her eggs in a light, fragile case that she accompanies upon the waves,
to act as a little "ark" for her young, until they hatch. This is the
shell which is pictured above.
Argonauta nouryi Lorois, 1852 is one of the rarest of the small family (only 8 known species), and its elongate shape makes it aesthetically superior to most. It is found only in a limited area off Western Mexico, and a lot of conchologists would KILL to obtain one :o).
