What animal has the largest RBC?

Amphibia
First, the vertebrates that appeared first have larger RBCs than do the birds and mammals. But, by far the largest RBCs are found in the Amphibia. The only other vertebrate with large RBCs is the lungfish.

What animals have red blood cells?

Vertebrates, including mammals, birds, amphibians, reptiles and fish also have red blood because they too use hemoglobin as an oxygen transport protein. Many spiders, centipedes, crustaceans and molluscs use an oxygen transport system called hemocyanin, a protein that is blue when it carries oxygen.

Which animal has smallest RBC?

✔Musk deer In mammals, smallest RBC is found in ‘musk deer’ (Moschus moschiferus) (2.5 m).

Which animal have red blood cells with nucleus?

Only mammals have anucleated red blood cells, and some mammals (camels, for instance) even have nucleated red blood cells. The advantage of nucleated red blood cells is that these cells can undergo mitosis.

Which animal does not have nucleus in RBC?

Hint: The RBCs of camels are similar to the other mammals with the difference in the shape of the RBC, and the presence or absence of a nucleus.

Which animals have no red blood cells?

Contents

• New Guinea’s Green-blooded Skinks.
• Crocodile Icefish.
• Octopuses.
• Horseshoe Crabs.
• Brachiopods.

Which animal has no red blood cells?

blackfin icefish
The Antarctic blackfin icefish is the only known vertebrate animal that lacks red blood cells containing hemoglobin. But the use of hemoglobin to transport oxygen through the body is actually a rarity among invertebrates, which rely on a variety of other pigments in their versions of blood.

Do camel RBC contain a nucleus?

Like all mammals, camel’s red blood cells do have the nucleus, that is they are nucleated and are oval instead of a round shape.

Is RBC present in camel?

The red blood cells of the dromedary camel protect it from dehydration because the oval‑shaped cells can circulate even in thick blood and can significantly expand during rehydration. This ability is, in part, due to uniquely oval red blood cells (which carry oxygen).
