Don't be fooled though, they make up for it with the interesting aspects they do have. Like five hearts that squeeze two blood vessels to push blood throughout their little bodies. Earthworms have mucus and little hairs covering their skin that allows them to move through different types of soil.
So, the answer to your question is that all segmented worms have blood, while roundworms and flatworms do not. The blood colour depends on the molecule that carries oxygen in that worm. And most worms have red blood, just like us!
Haemoglobin contains iron, which means most worm blood – including that of earthworms and leeches – is red.
An earthworm circulates blood exclusively through vessels. There are three main vessels that supply the blood to organs within the earthworm. These vessels are the aortic arches, dorsal blood vessels, and ventral blood vessels. The aortic arches function like a human heart.
Midges are often seen in large mating swarms over water. They lay their eggs in the water and in about ten days these eggs hatch to form larvae, often called red worms–or “bloodworms”–because of the presence of hemoglobin in the blood.
They might sense something, but it is not painful and does not compromise their well-being."

Do worms have brains? Yes, although they are not particularly complex. Each worm's brain sits next to its other organs, and connects the nerves from the worm's skin and muscles, controlling how it feels and moves.
Thinking and feeling: Worms have a brain that connects with nerves from their skin and muscles. Their nerves can detect light, vibrations, and even some tastes, and the muscles of their bodies make movements in response.
The short answer is ants have something similar to blood, but scientists call it “haemolymph”. It is yellowish or greenish. In vertebrates (animals with backbones such as humans, cats, dogs, snakes, birds and frogs) blood's main job is to move important things around the body.
Roundworms don't have eyes or the light-absorbing molecules required to see. Yet, new research shows they can somehow sense color. The study, published on March 5 in the journal Science, suggests worms use this ability to assess the risk of feasting on potentially dangerous bacteria that secrete blue toxins.
In other words, worms can sense colors despite lacking eyes and opsins. “Opsin molecules were previously thought to be required for color detection,” Ghosh said. “Our work tells us that we have so much more to learn and explore about how animals sense light.”
Snails, Spiders, and Octopi all have Blue Blood.
Earthworms are hermaphrodites, meaning an individual worm has both male and female reproductive organs. Earthworm mating typically occurs after it has rained and the ground is wet. They emerge from the soil and jut out their anterior end.
Worms don't bite. They also don't sting. 3. They are cold-blooded animals, which means they don't maintain their own body heat but instead assume the temperature of their surroundings.
Baby worms develop in cocoons. They are babies for 60 to 90 days and it takes them about a year to become an adult. Worms can live for up to 10 years. Worms don't have a stomach.
Elephants, cats, flies, and even worms sleep. It is a natural part of many animals' lives. New research from Caltech takes a deeper look at sleep in the tiny roundworm Caenorhabditis elegans, or C. elegans, finding three chemicals that collectively work together to induce sleep.
Worms Exhibit Fear and Respond to Anti-anxiety Meds | Technology Networks.
Yes, it is now accepted that worms feel pain – and that includes when they are cut in half. They do not anticipate pain or feel pain as an emotional response, however. They simply move in response to pain as a reflex response. They may curl up or move away, for example, from painful or negative stimuli.
We show that worms exhibit environmental familiarization, and that this memory persists for at least 14 days – long enough for the brain to regenerate.
All worms are not asexual. For instance, earthworms are hermaphroditic organisms. Hermaphrodite is an individual that has both male & female reproductive organs. However, worms without sexual organs reproduce through fission.
They could perceive and remember; they felt pain and pleasure; they could express emotions (hope, fear, grief, etc.) and, in many cases, they even made speech-like noises, all of which was indicative of rational thought.
Does it have bones? No, worms are invertebrates, they have no bones.
That's right, four out of every five animals on earth are nematode worms. Microscopic soil nematodes in action. Microscopic soil nematodes in action. A new study of soil nematodes co-authored by Adams reveals that there are 57 billion of them for every single living human being — much greater than previously estimated.
Worms DO have a pulse and you can actually see and count the pulses.
