Spiders that don't use webs to catch their prey are known as hunting spiders. They actively stalk and hunt down their prey instead of relying on webs to trap them. Examples of hunting spiders include wolf spiders, jumping spiders, and crab spiders.
Lobsters have gills located under their carapace, which extract oxygen from water as it passes over them. The gills are essential for breathing and provide lobsters with the oxygen they need to survive. Lobsters also have a respiratory pigment called hemocyanin in their blood that helps transport oxygen throughout their bodies.
Well, female mosquitos do, as they need the protein and iron. But no spiders (that come up in search, anyway)
No, octopuses don't have red blood. Instead they have blue blood because they use an oxygen- carrying molecule in their blood which contains copper.
Yes, mammals typically have red blood due to the presence of hemoglobin, which binds oxygen. Insects have a different oxygen transport system using hemolymph, which can appear yellowish due to the presence of other pigments. Lobsters and some other arthropods have blue blood because they use hemocyanin, a copper-containing protein, to transport oxygen.
lobsters protect themselves by hiding in holes at the bottom of the ocean of they use there claws.
Lobsters use their antennae and chemosensory organs to navigate their environment and locate food.
spiders use this so they can breathe
Spiders eat most of an insect. Some spiders are capable of chewing up the entire body of whatever it has caught, flooding the chewed up mass with digestive fluid, and then sucking up the digested food. Other spiders are not capable of chewing up the exoskeleton of a prey item, so they inject digestive fluids into the body, let the contents of the exoskeleton digest, and then suck that up.
