• The vanabins extracted from tunicate vanadocytes are often called hemovanadins.
• The use of vanabins and vanadium for oxygen transport in ascidians and tunicates is doubtful.
• Vanabins on the other hand have a moderate dissociation constant and do not tightly bind vanadium.
• Vanabins are found almost exclusively in the blood cells, or vanadocytes of some ascidians and tunicates ( sea squirts ).
