Invertebrates can be simply identified as animals that do not have a backbone. To compensate for the lack of an internal skeleton, most invertebrates have an external skeleton that protects their soft, inner body.
Invertebrates compensate for their inability to possess a backbone ( spine ) by having ; An external skeleton ( exoskeleton )
Invertebrates are animals without backbone and also lacks an internal skeleton. The exoskeleton present in invertebrates helps in the protection of the outer surface of the organism from external stimuli and also aids in the movement through internal muscles.
Invertebrates compensates for the absence of a backbone through the possession of an exoskeleton which performs similar function just like the endoskeleton.
Hence we can conclude that Invertebrates compensate for their inability to possess a backbone ( spine ) by having ; An external skeleton ( exoskeleton ).
