anatomical cluster infraorbital series Anatomical cluster that is the series of dermal bones surrounding the orbit and associated with the infraorbital sensory canal. TAO:0001709 The infraorbital series may include the antorbital, a variable number of infraorbitals, and dermosphenotic (or posteriormost dorsal infraorbital). The infraorbital series may be formed by seven (primitively) or less bones in teleosts. Consequently, the so called dermosphenotic may correspond to the seventh, sixth or fifth bone, etc., depending on the taxon. circumorbital series teleost_anatomy
