Renal Kidneys are part of the excretory system. Which also includes the bladder, ureter, urethra. The skin and lungs are also considered excretory organs.
Spiders are arachnids, not insects. The main differences are that spiders have eight legs, two body segments, and no antennae, while insects have six legs, three body segments, and antennae.
The main excretory organs that remove water from the body are the kidneys. Kidneys filter blood to remove wastes and excess water, which is then excreted as urine.
Because spiders have 8 legs and because spiders have 2 main body parts.

DUH its simple! Insects have 6 legs, and arachnids (spiders) have 8 legs. Spiders spin webs, insects cannot. I am only 13 and I know a lot of differences between the two. Spiders have 2 body parts the main part and the abdomen, where insects can have more or less. Spiders have fangs, insects do not. Some insects can fly, and a rock would speak before a spider could fly. Insects can be herbavors, carnivors, or omivors, where spiders are only carnivorous. Spiders usually prey upon insects, not the other way around.
The main parts of the excretory system are the kidneys, ureters, bladder, and urethra. These organs work together to eliminate waste and maintain the body's balance of fluids and electrolytes.
The main function of the excretory system is to get rid of wastes from the body. It is actually composed of many different structures and organs in other systems of the body. The organs that contribute are ones like the lungs, skin, liver, kidneys, colon, and bladder, just to name a few.
A main characteristic of all insects is a pair of antennae located on their heads. They are the sensing organs in arthropods.
Spiders are different from insects in several ways. One key difference is their body structure - spiders have two main body parts (cephalothorax and abdomen) while insects have three (head, thorax, and abdomen). Additionally, spiders have eight legs and no antennae, while insects have six legs and usually have antennae. Another difference is in their feeding habits - spiders are carnivorous and use venom to catch and digest their prey, while most insects are herbivores or omnivores.
The antenna are the main organs of the sense of smell. One of the main odors sensed are sex pheromones.
all INSECTS do. that's what makes them INSECTS. not ARACHNIDS, INSECTS. put it under the right category next time please, because grasshoppers aren't spiders, they're INSECTS. spiders are ARACHNIDS. there's a difference, besides the obvious fact all INSECTS have 6 legs, and ARACHNIDS have 8
