All those animals that have haemocyanin as the respiratory pigment have their blood blue when oxygenated. Haemocyanin is the respiratory pigment akin to haemoglobin but hemocyanin has copper as the cofactor instead of iron which you find in haemoglobin. Animals belonging to class crustacea and those belonging to phylum Mollusca have hemocyanin, and hence they have blue blood. Some notable crustaceans are crabs, lobsters, shrimps. Some notable mollusks include Snails, whelks. mytilus, oysters, chitons, squids, sepia, octopus. Limulus, called a horseshoe crab, also has hemocyanin.

Spider blood is usually blue due to the presence of the copper-based molecule hemocyanin, which helps transport oxygen throughout their bodies. Hemocyanin turns blue when it binds with oxygen, giving spider blood its distinctive color.
The main reason we need blood is to transport oxygen from our lungs to other parts of our body. Humans and other animals use a molecule called hemoglobin to pick up and deliver oxygen. Hemoglobin is a very large molecule but since bugs are so small and don't need so much oxygen they use a simpler molecule called hemocyanin.The reason that the blood is of different color is that the molecules contain two different metals:# Hemoglobin in humans contains iron. When you leave something made of iron outside for a long time it rusts. Rust is red as you have probably seen. # Hemocyanin in bugs contains copper. When copper is left outside it patinates. Patina is green (look at the statue of liberty). Both rust and patina is a sign that the metal has picked up oxygen.
The bug that has purple blood is called the violet ground beetle (Carabus problematicus). Their blood contains a pigment known as hemocyanin, which gives it a purple color. Hemocyanin helps transport oxygen in the beetle's circulatory system.
Hemocyanin is a copper-containing protein found in the circulatory system of many mollusks and arthropods. It functions in oxygen transport, similar to the iron-containing hemoglobin in vertebrates. Hemocyanin turns blue when oxygenated, giving these animals their characteristic blue blood.
Some animals (like horseshoe crabs) have blue blood because they use hemocyanin carry oxygen to their tissues instead hemoglobin like we do. The copper in the hemocyanin makes their blood appear blue.
They actually have an open circulatory system, because their bodies do no contain blood vessels and their blood contains hemocyanin, rather than hemoglobin.

The two major components of squid blood are hemocyanin, a copper-containing respiratory pigment that transports oxygen, and hemolymph, a fluid that acts as both blood and lymph in invertebrates. Hemocyanin gives squid blood a blue color when oxygenated.
all animals
Crustaceans and mollusks use a copper-based protein called hemocyanin to carry oxygen in their bodies instead of hemoglobin, which is iron-based. Hemocyanin is found dissolved in their hemolymph, the equivalent of blood in these animals, and gives their blood a blue color when oxygenated. This adaptation allows them to efficiently transport oxygen in their aquatic environments.
Blood color in animals varies primarily due to the type of respiratory pigment present. Most vertebrates, including humans, have red blood due to hemoglobin, which contains iron. Insects and some crustaceans have blue blood because their hemolymph contains hemocyanin, which uses copper for oxygen transport. Other variations include green blood in some worms and leeches due to chlorocruorin, and purple blood in certain species of octopus, which also rely on hemocyanin.

No animals do, and only green plants do.
Plants and animals are eukaryotes.
