Which is not exclusive trait of Arthropodaa)Presence of wingsb)Joined ...
- The phylum Arthropoda is the largest and most varied in the animal kingdom. It includes well over one million described species.
Arthropods also have appendages with joints (the word "arthropod" means "jointed feet").
- Some arthropods have highly developed sense organs. Most species have paired compound eyes , and many also have a number of simpler eyes called ocelli. Arthropods have an open circulatory system (without blood vessels) that consists of a tube that is the heart and an open hemocoel , the coelom of the animal, in which blood pools.
- All arthropods possess a stiff exoskeleton (external skeleton) composed primarily of chitin .hence,option (A) is correct.

Right answer is a. jointed appendages (arthro + pod) haemocoel and chitinous skeleton is exclusive feature of all arthropods. but wings are not exclusive features as they are not present in all arthropods. for example- insects like ant etc

Arthropoda is a phylum of invertebrates that includes insects, arachnids, crustaceans, and other related groups. They are characterized by several unique traits, but not all of them are exclusive to this group. The following are some of the traits that are not exclusive to Arthropoda:
Haemocoel
- The haemocoel is a body cavity that contains blood and other fluids. It is present in many invertebrates, including arthropods, mollusks, and annelids.
Chitinous exoskeleton
- Chitin is a tough, protective substance that forms the outer covering of arthropods and some other invertebrates. However, other groups such as mollusks, also have protective shells made of different materials.
Joined appendages
- Arthropods have a unique body plan in which their limbs are joined to their body in pairs. However, other groups such as annelids, have segmented bodies with paired appendages.
Presence of wings
- While many arthropods have wings, some do not. Additionally, some insects in other groups, such as the silverfish, also have wings.
In conclusion, while Arthropoda has several unique traits, not all of them are exclusive to this group. Other invertebrates share some of these traits, although they may differ in their specific form or function.
