And is it always red? What's that green stuff that comes out of squished caterpillars?
Do insects and bugs have blood?
Oooh 4 for the price of 1 :-)

Not every living creature, most members of the kingdom Animalia however do. This includes all insects, mammals, spider, crabs, fish etc. Not all blood is red though. The colour of blood is dependent on the molecule used to transport oxygen around the body. Crabs for example use haemocyanins which give the blood a green colour, tunicates use vanabins which is vandadium based, our blood is red because we use haemaglobin which is iron based and it is this that gives our blood a red colouraton. Antarctic ice fish live in such highly oxygnated water that they do not need a molecule to transpoprt oxygen through there body and the blood is comlpetely colourless. Insects the blood (Haemolymph) is not for oxygen transportation but for waste removal and nutrient transport. The green is likely partily digested plant material.
Some multicellular organism still lack a transport system such as porforeia (sponges) and cnidaria (jellyfish).

Actually not every living creature has red blood. The red comes from iron which is a component of haemoglobin which is what carries oxygen around the body. But the same principle can be used to substitute anything for the iron so its possible a solution of copper sulphate could substitute which would make greenish blood, and some living things use photosynthesis (chlorphyll) and insects often have an ichor instead of blood as we know it.

Many invertebrate animals such as coral, jelly fish and flat worms do not have blood because they are able to absorb nutrients and move gases and wastes directly to the outside of their bodies so they d not need the complex system and organs we have.
Insects do have blood -- sort of. It's usually called hemolymph (or haemolymph) and is distinguished from human blood and the blood of most animals that you would be likely to have seen by an absence of red blood cells. In a sense hemolymph plays a sort of double role, doing the jobs that both blood and the lymphatic system do in humans and other vertebrates.

all animals hav blood but some animals lack haemoglobin pigment(responsible for the red colouration of blood) and so their blood are known as haemolymph..the fluid which comes out of squished caterpillars is the body fluid or somatic fluid.yes insects and bugs do have blood.

no
mammals have blood and lots of other animals but the likes of jelly fish don't and some sea life don't have blood other animals would have blood and the reason that it is red is because it is mixed with oxygen
the green stuff in caterpillars is the cabbage or other vegetation that it has eats but has not digested yet
insects and bugs do have blood but in very small amounts that wouldn't be seen when you stand on them unless they are big bugs and then sometimes you will see a little bit of blood

well every living creature does have a kind of blood.
in humans its red due to the presence of "haemoglobin" in the red blood cells
in other animals like caterpillars etc, it isn't red in colour but the liquid serves the purpose of blood, just like in humans. Its called "hemolymph".

not all creatures have blood - unicellular organisms (bacteria, fungi) and plants for example don't have blood. And blood is not always red - in humans it looks red from the iron ion inside. Other animals can have different coloured blood such as crab's blood is blue due to the copper ion inside.

Trees and plants don't have blood and they are living and multicelled. *Thinks back to biology A-level* not all creatures need blood as blood transports oxugen around the body, so if an animal had sufficient surface to volume ratio to just absorb enough oxygen through its surface they may not have blood or a circulatory system, like a flat worm or sponge.

it dosnt have to be red or green but evrey fliud in living creatures is it blood cos it kept it alive as long it heart beat.
