The appendages of the crayfish attach to both the cephalothorax and the abdomen. The appendages that attach to the thorax are called WALKING LEGS and you can see how they are jointed in the figure below. The smaller appendages attached to the segments of the abdomen are called SWIMMERETS.

What is a thoracic appendage?
In the adult form, the head region contains four pairs of appendages that are used for swimming, walking, and feeding. The thoracic region features three pairs of appendages that are used or adapted for feeding, creeping, and cleaning of the shells.
How many appendages does a crayfish have?
The strong, long, muscular abdomen has ten tiny appendages (the pleopods) which aid in swimming movements. When threatened, the crayfish propels itself backward quickly with strong flips of the telson, located at the tip of the abdomen.
What appendages do crayfish use to eat?
Of the eight pairs of appendages on the cephalothorax, the first three are maxillipeds, which hold food during eating. The chelipeds are the large claws that the crayfish uses for defense and to capture prey. Each of the four remaining segments contains a pair of walking legs.
What are the appendages of crustaceans?
Crustaceans are generally aquatic and differ from other arthropods in having two pairs of appendages (antennules and antennae) in front of the mouth and paired appendages near the mouth that function as jaws.
What is an appendage in medical terms?
(uh-PEN-dij) In medicine, a body part (such as an arm or leg) that is attached to the main part of the body.

An appendage is defined as an extra part that is attached to something. An example of an appendage is a leaf added to a dining table for extension.
Which appendages are Biramous in crayfish?
Note that each pair of antennae are biramous appendages. Examine the telson and uropod. How does the crayfish use these biramous appendages to escape predators? Using a probe, try to find the mouth and anus.
What are the functions of the appendages that are found on the cephalothorax?
…often referred to as the cephalothorax. A pair of appendages is attached to each somite. The first two pairs, the first and second antennae, consist of a segmented stalk and flagella, and serve such sensory functions as olfaction, touch, and balance. The remaining three head appendages are either the crushing…
What are types of appendages?
In invertebrate biology, an appendage refers to any of the homologous body parts that may extend from a body segment, including antennae, mouthparts (including mandibles, maxillae and maxillipeds), gills, locomotor legs (pereiopods for walking, and pleopods for swimming), sexual organs (gonopods), and parts of the tail ...
What are arthropods appendages?
Arthropods have segmented bodies. Each body segment usually has a pair of appendages. The appendages can be antennae, wings, legs, or mouthparts! Body segments are connected by movable joints.
What is the appendages of prawn?
There are five pairs of cephalic appendages: the antennules, the antennae, the mandibles, the maxillulae and the maxillae. The antennule (first antenna) is situated in front of the mouth just behind the base of the eye-stalk.
How many appendages do grasshopper have?
Like all insects, all species of grasshopper have a three-part body that is made up of the grasshopper's head, it's thorax and the abdomen. Grasshoppers also have six legs, two pairs of wings, and two antennae.
Which crayfish appendages are involved in respiratory movements?
Crayfish, like all large crustaceans, use gills to gather oxygen. Found in the sides of the body and at the base of each leg, these gills behave like those of most aquatic creatures, pulling oxygen into the bloodstream as water passes through them.
Which crayfish appendages ends in a large claw?
Of the eight pairs of appendages on the cephalothorax, the first three are maxillipeds, which hold food during eating. The chelipeds are the large claws that the crayfish uses for defense and to capture prey.
