High impact information on Polyplacophora

• We used the polymerase chain reaction (PCR) to amplify, clone, and sequence 10 engrailed homeodomains from 8 species in the five major molluscan classes, including the serially organized chiton (Polyplacophora) lineage [1].
• Although muscle tissue Hbs or myoglobins (Mbs) are usually monomeric, with non-cooperative O2 binding, the radular muscles of gastropod molluscs and chitons have homodimeric Mbs that bind O2 cooperatively [2].
• Daily stress protein (hsp70) cycle in chitons (Acanthopleura granulata Gmelin, 1791) which inhabit the rocky intertidal shoreline in a tropical ecosystem [3].
• To examine the effects of lanosol on the profile of biochemical defenses in C. stelleri, chitons were gavaged daily with 0, 1, 2.5, 5, or 10 mg/kg of lanosol [4].
• Naturally magnetic, biologically precipitated magnetite (Fe3O4) has been found in chitons, magnetotactic bacteria, honey bees, homing pigeons, and dolphins [5].
