Definitions
Scale
- A non-articulated cuticular extension of which the base is generally very wide relative to its length; microscopic secondary features may arm the outer margin; this term should not be used to describe very small extensions of setal shafts. [Watling, 1989]
- In cirripeds (Lepadomorpha), platelet on side of peduncle.
See: Scaphocerite [Moore and McCormick, 1969] - see Antennal scale. [Butler, T. H.]
- Small calcareous plates on peduncle of lepadomorph Cirripedia; see also scaphocerite. [McLaughlin, 1980]
- (Taxon-specific: Order Isopoda) A small articulate piece occurring on the antennules or antennae in some crustaceans, thought to be a remnant of the second ramus (presumably the exopod). Scales rarely occur in isopods. [Wetzer et al. 1997]
- (Taxon-specific: Subclass Cirripedia) One of numerous small calcareous elements on stalk (peduncle) of barnacle. [Stachowitsch, 1992]
