Cephalaspidea - AccessScience from McGraw-Hill Education.
The vast majority of Cephalaspidea live just beneath the surface of the sand and are rather dull in their coloration. They all emit copious amounts of slime. It was a largely carnivorous predatory group which dominates the marine sandy and muddy environments in which dwell a rich harvest of relatively immobile bivalves and polychaetes.

Haminoeidae is the most diverse family of Cephalaspidea with 13 to 17 genera commonly recognised as valid and with 46 genera that historically have been moved back and forth between Haminoeidae and other families. Due to poor definition of most genera the family is plagued by extensive taxonomic confusion and its generic composition and internal relationships remain uncertain. In this work we.
An order of marine gastropods assigned to the informal group Opisthobranchia (phylum Mollusca) and often referred to as head-shield sea slugs or bubble shells. The name Cephalaspidea was introduced in 1887 by the French naturalist Paul Henri Fischer.

Cephalaspis (head shield) was a genus of armoured fish in the early Devonian about 400 million years ago (mya). It was one of the jawless fishes, or ostracoderms, which were common at the time.They were discovered in the first half of the 19th century in the Old Red Sandstone of Britain. Cepalaspis was described and pictured in a popular work on the rocks and fossils of the Old Red Sandstone.
