How many animals blood is not present and name of that living thing
Answers
Ok then, for the sake of discussion, let us rephrase the question as “Do all animals have blood?”. The answer is still…. No. Marine sponges are still considered animals and yet they have no circulatory system and thus no blood. However most “advanced” (eg further along the evolutionary tree) have blood. Animals of phyla up to and including Nematoda do not have a circulatory system and thus cannot have blood. However,by the time of the the next phylum and up up, the segmented worms(Annelida) animals start having a circulatory system and thus can have “blood”. Mollusk and crustaceans have blood, however it is not red. It is blue because the oxygen pigment is hemocyanin a copper based compound. Insects also have something akin to blood, it is called hemolymph because an insect circulation system is “open” (the piping doesn't run all the way back, instead the blood accumulates and diffuses back). Also, hemolymph usually doesn't contain a oxygen carrying pigment because most insects are small enough that they get enough oxygen through diffusion from the air system. Thus insect blood is mostly clearish yellowish. Only vertebrate blood is red.
So in conclusion, no not all living things have blood, and not all blood is red
No, not all living things have blood. For example, Protista and bacteria don't have blood because they are unicellular. One definition of blood states “Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.” .[1] Plants also arguably don't have blood as they are not animals. Yet all of these three kingdoms(sorry I'm using the old system) are considered living things.
