Copepods follow the basic crustacean pattern of
limbs or appendages. From the front to the back,
they have the following sequence of appendages,
one pair per basic body segment In the
Cephalosome The first antennae, also known as
antennules. The second antennae, also known
simply as antennae (if the first antennae are
called antennules. The mandibles, or jaws. In
some predatory Calanoids, these may be tipped
with opal (amorphous silica), presumably to
harden the jaws so that they may more effectively
crush their prey. The first maxillae, also known
as the maxillules, The second maxillae, also
known as maxillae (if the first maxillae are
called maxillules. In the Metasome Four or five
pairs of thoracic appendages, all of more-or-less
similar architecture, except in the male, where
the last pair of thoracic appendages is modified
as copulatory organs. In the Abdomen There are
no appendages. This is different from the
situation found with the crabs and shrimps, where
there are paired appendages under each abdominal
segment.
