Which characteristic is shared by all arthropods? a) calcified hard shell b) endoskeleton c) jointed legs d) gills

Endoskeleton is a characteristic shared by all arthropods.

Further Explanation:

Arthropods are the largest group of animals in terms of a number of species. They include aquatic (Crustaceans) as well as terrestrial organisms. They are a phylum that comprises of animals that possess:

• Exoskeleton - provides protection against predators, provides a surface for muscle attachment. The exoskeleton of arthropods is made up of chitin and protein, providing a solid covering and helps in the contraction of muscles attached to it.

• They have a segmented body.In some cases, these segments fused to form tagmata and divided into head, thorax, and abdomen. The head can fuse with thorax to form cephalothorax in some insects. The head can fuse with thorax to form cephalothorax in some insects.

• Paired jointed appendages are present. The appendages can be modified into legs, antennae, and wings.

• The animals possess a well-developed nervous system and the brain act as a control point.

• They have the most efficient modes of locomotion.

• Have an open circulatory system.
