Fibrous and cartilaginous endoskeleton - Cyclostomata

Vedclass · Answer

(A) $1$. Cyclostomata (e.g.,lampreys and hagfish) possess a cartilaginous cranium and vertebral column,but they do not have a 'fibrous' endoskeleton in the context of typical biological classification; however,the term 'fibrous' is not a standard descriptor for their endoskeleton. $2$. Chondrichthyes (cartilaginous fishes) have an endoskeleton composed entirely of cartilage. $3$. Echinoderms possess an endoskeleton consisting of calcareous ossicles (calcium carbonate plates). $4$. Osteichthyes (bony fishes) have an endoskeleton composed of bone. $5$. Therefore,the pair 'Fibrous and cartilaginous endoskeleton - Cyclostomata' is considered the mismatched pair as 'fibrous' is not the defining characteristic of their endoskeleton.
