Crustaceans have two pair of antennae. Another set of anterior appendages are modified as mandibles, which function in grasping, biting, and chewing food.

Do crustaceans have one pair of antennae?
Crustaceans, like lobsters, crabs, and shrimp, have two or three body segments. They often have three pairs of appendages for chewing, and at least five pairs of legs. Crustaceans are the only arthropods that have two pairs of antennae.
How many antennae and mandibles do crustaceans have?
All crustaceans have: A hard, but flexible exoskeleton or shell. Two pairs of antennae. A pair of mandibles (which are appendages used for eating)
How many antennae are there?
Shapes. Because antennae serve different functions, their forms vary greatly. In all, there are about 13 different antennae shapes, and the form of an insect's antennae may be an important key to its identification.
How many pairs of antennae do shrimp have?
Shrimp have two pairs of segmented sensory antennae, a tail fan, and compound eyes.
Do crustaceans have antennae?
Crustaceans have two sets of antennae: short antennules (first antennae) and antennae posterior or lateral to them (second antennae) which are often much longer.
How many antennae do arachnids have?
Unlike insects, arachnids have eight legs and no antennae or wings, and their body is divided into two main segments: A cephalothorax and abdomen.
How many body parts and antennae do crustaceans have?
Crustaceans have three distinct body parts: head, thorax, and abdomen (or pleon), although the head and thorax may fuse to form a cephalothorax. The head bears two pairs of antennae, one pair of compound eyes and three pairs of mouthparts.
How many terrestrial crustaceans are there?
Crustaceans are a group of invertebrate animals consisting of some 45,000 species worldwide. Crabs, lobsters, and shrimps are all counted among the subphylum Crustacea.
Are crustaceans Biramous or Uniramous?
The evolution of biramous appendages in crustaceans is central to the debate on the origin of the arthropods. It is proposed that the biramous limb evolved through the basal fusion of adjacent pairs of ancestrally uniramous appendages.
What are filiform antennae?
Filiform is a term used to describe any structure that is long and thin and with a uniform cross section (i.e. the structure doesn't taper). In entomology, the term is most often used in the context of filiform antennae. Filliform antennae are the most basic form of insect antennae.
Are antennae appendages?
antenna), sometimes referred to as "feelers", are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments.
How many antennae does a prawn have?
Prawns have two pairs of antennas.
How many antennae do Decapods have?
Decapods have three pairs of appendages, or maxillipeds, on their heads that make up their mouthparts. They also have two pairs of antennae on their heads.
How many legs do crustaceans have?
Another arthropod with many legs is a crustacean: the crab. The crab is a decapod, meaning it has ten legs; eight of these legs are used for mobility, and two are used for capturing food and for defense. Like insects, crabs have complex eyes, which allow them to see in multiple directions.
