What color is the blood of a spider and what is the super small blood red spider called?

Spider blood is blue-green.

Spiders and other arthropods do not have hemoglobin in their bodies, but instead have a protein called hemocyanin, which contains copper instead of iron. However, hemocyanin does not attach to any cell in an organism like hemoglobin, it only flows freely in the circulatory system. When an oxygen atom binds to hemocyanin, it does not turn crimson but pale blue-green, as we all learned in chemistry class, copper becomes pale blue-green when oxidized.

This effect is not so pronounced in spiders, as their bodies contain only a small amount of bloodlymph; However, in larger arthropods, there is blue blood flowing through the body.

Generally speaking, the color of blood is determined by some elements of hemochromatin, because some colors formed during the evolution of various animals are actually different, and the blood of some animals may be blue-green and blue. So the color of the blood is also a variety of colors, and generally speaking, the blood of spiders is green.

Green. The blood of molluscs and arthropods is blue or turquoise (there are exceptions) because the serum protein that transports oxygen in such animals is hemocyanin, the blue copper protein (Cu2+), and spiders are arthropods and the blood should be turquoise.

The heart of a spider does not have an obvious heart like that of humans or other mammals, but the circulatory system is very simple, consisting of a tubular heart with multiple pairs of orifice, arteries, veins, and some blood sinuses from the front of the heart.

Invertebrate.

For example, the blood of shrimp, spiders, squid, etc., is cyan, and this blood contains a pigment called "hemocyanin".

The color of the butterfly's blood is not red, but green. Unlike humans, butterflies do not have hemoglobin in their blood and do not transport oxygen, but instead provide nutrients, various hormones, and enzymes to their cells.

The scientific name of a very small blood-red spider should be called leaf mites, also known as red spiders, spiders.

1) Leaf mites are small, round or oval, with a body length of 1 mm, and large species can reach 1 mm. There are red, orange, brown, yellow, green and other colors. There are black spots on the sides of the body, 1 pair of eyes on each anterolateral side, the body wall is soft, and the epidermis is linear, reticulated, granular or folded.

There are rows of dorsal hairs on the back, generally no more than 16 pairs, bristle-like, leaf-like, or club-shaped. The chelicerae are needle-like and located within a retractable needle sheath. The jaw includes 1 pair of barbels and mouthparts, 5 barbels, and 6 7 bristles on the tarsal joints of the barbels.

The valve groove is well developed and located at the base of the jaw body. The tarsal claws of each foot have sticky hairs, with or without sticky hairs between the claws. The foot and tarsus usually have one sensory hair and one tactile hair, which is called a double hair.

The reproductive area of female mites is folded, and the reproductive pores are transversely lobed.

2) This insect is very small, less than 1 mm, round or oval, orange or reddish-brown, because of the small body is not easy to find, once it is found to be a pest, often the flower damage is relatively heavy. This insect pest method is to pierce the mouthparts into the leaves and suck the sap, so that the chlorophyll is destroyed, and the leaves appear gray and yellow spots or patches, and the leaves are orange, fall off, and even fall light.

3) Commonly used pesticides include mite, dicofol, etc. In 400 ml of water, gram mites or quick killing or flower insects can be dropped into 4 drops (equivalent to 2000 times the liquid medicine), shake well after adding the medicine, and then spray, spraying requirements are uniform, especially pay attention to spraying the back of the leaves. When spraying, it is best to move potted flowers outdoors, such drugs are toxic and should be used with caution.

Leaf mites, also known as spider mites.

There are many species of red spiders on jujube trees, and the dominant species in jujube orchards with jujube grain intercropping is truncate leaf mites, which have a wide range of parasites, including jujube trees, cotton, corn, beans and a variety of weeds and vegetables.

Spider mites lay about 100 eggs once a year, and after a month they begin to hatch, and the mother spider waits day and night, and is willing to be the first food for her child, teaching her child to hunt, but sacrificing herself.

The spider's blood is turquoise. Spiders are arthropods, and the blood of molluscs and arthropods is blue or turquoise (with some exceptions), because the serum protein used to transport oxygen in these animals is hemocyanin, the blue copper protein (Cu2+), which turns pale blue-green when oxidized. Therefore, the spider's blood is turquoise.
