Panopea glycimeris is a species of large marine bivalve mollusc in the family Hiatellidae.

[1][2] The fossil record of this species dates back to the Miocene of Italy (age range: 23.03 to 7.246 million years ago).

[3] Shells of Panopea glycimeris can reach a size of 250–295 millimetres (9.8–11.6 in).

The diameter of the siphonal apertures ranges between 5 and 7 cm.

[5] This species can be found in the Mediterranean Sea and in the Northwestern coast of Africa, on sand bottom at depths of 10 to 100 m. It is actually rare in the Mediterranean Sea.
