Why camel's RBC are nucleated?

Answer 1

 

RBC has a nucleus in its early stage which is extruded after some time and then RBC is destroyed after some time of the extrusion of its nucleus.The life span of RBC in the circulation after extrusion of its nucleus is important.If the time span is long then every one will observe that the RBCs are anucleated and if the life span is short then every one will call the RBCs as nucleated.

In camel the life span of RBCs after extrusion of its nucleus is very short therefore everyone is reffering nucleated RBCs in Camel.

The question cited, namely, "Why camel's RBC are nucleated?", remains unanswered by Guest11213355. Also, since the  camel is a mammal and the author states that, "...only mammals lack nucleated RBCs,...", the question needs to be rephrased as, "Why camel's RBC are nucleated, although the camel is a mammal?". In response to the cited question, the author only differentiates the camel's RBCs by their shape and states that, "camel RBC's are **oval** in shape, unlike the **circular** biconcave disc shaped RBC of other mammals." Regards.

Answer 3

camel RBC's are **oval** in shape, unlike the **circular** biconcave disc shaped RBC of other mammals. This is how camel RBC's are different from RBC's of other mammals. The mature circulating RBC's of all mammals are without nucleus, and there is no exception to this. Also note that among vertebrates (mammals, reptiles, birds, amphibians and fishes), only mammals lack nucleated RBC's, while other class of vertebrates have nucleated RBC's.
