DEPRESSOR MUSCLE CRESTS

In cirripeds (Balanomorpha), elevated denticles on interior of tergum near basicarinal angle for attachment of depressor muscles (crests may extend apically) [Moore and McCormick, 1969].

Barnacle plate feature: on inner surface of tergum in unstalked form, elevated denticles or ridges near basicarinal angle. Serves as site of attachment of depressor muscle [Stachowitsch, 1992].

Elevated denticles or ridges on inner surface of tergum near basicarinal angle for attachment of depressor muscles (balanomorph Cirripedia) [McLaughlin, 1980].

(ARTHROPODA: Crustacea)

In balanomorph barnacles, elevated denticles or ridges on the inner surface of the tergum near the basicarinal angle for attachment of the depressor muscles.
