Protobranchia is a
.These are deep water clams of a small and primitive order with a taxodont hinge (composed of many similar, small teeth), generally with a central ligament pit, large labial palps which are used in deposit feeding and the
nonhomologous byssal gland in the heel. The byssal gland in these clams does not produce threads as in Pteriomorphia.[2]
