Protobranchia, a Common card

The card carries these facts from its Wikipedia article.

• These are deep water clams of a small and primitive order with a taxodont hinge, generally with a central ligament pit, large labial palps which are used in deposit feeding and the gills used only for respiration, the anterior and posterior adductor muscles are nearly equal in size, a foot which is divided sagittally and longitudinally with papillate margins.
• The foot in Protobranchia clams is without a true byssus gland, although they frequently have a nonhomologous byssal gland in the heel.
• The byssal gland in these clams does not produce threads as in Pteriomorphia.
