Like other arthropods, spiders are coelomates in which the coelom is reduced to small areas around the reproductive and excretory systems. Its place is largely taken by a hemocoel, a cavity that runs most of the length of the body and through which blood flows. The heart is a tube in the upper part of the body, with a few ostia that act as non-return valves allowing blood to enter the heart from the hemocoel but prevent it from leaving before it reaches the front end. However, in spiders, it occupies only the upper part of the abdomen, and blood is discharged into the hemocoel by one artery that opens at the rear end of the abdomen and by branching arteries that pass through the pedicle and open into several parts of the cephalothorax. Hence spiders have open circulatory systems. The blood of many spiders that have book lungs contains the respiratory pigment hemocyanin to make oxygen transport more efficient. Spiders have developed several different respiratory anatomies, based on book lungs, a tracheal system, or both. Mygalomorph and Mesothelae spiders have two pairs of book lungs filled with haemolymph, where openings on the ventral surface of the abdomen allow air to enter and diffuse oxygen. This is also the case for some basal araneomorph spiders, like the family Hypochilidae, but the remaining members of this group have just the anterior pair of book lungs intact while the posterior pair of breathing organs are partly or fully modified into tracheae, through which oxygen is diffused into the haemolymph or directly to the tissue and organs. The tracheal system has most likely evolved in small ancestors to help resist desiccation.[14] The trachea were originally connected to the surroundings through a pair of openings called spiracles, but in the majority of spiders this pair of spiracles has fused into a single one in the middle, and moved backwards close to the spinnerets. Spiders that have tracheae generally have higher metabolic rates and better water conservation. Spiders are ectotherms, so environmental temperatures affect their activity.

Based on key anatomical features, sharks, rays, and guitarfish can be distinguished primarily by the position of their gill slits, the shape of their bodies, and their primary mode of movement. All three are cartilaginous fish, but guitarfish are a species of ray that has an intermediate body form, often causing them to be mistaken for sharks. Have five pairs of gill slits located on the underside (ventral side) of their bodies. To breathe while resting on the ocean floor, they use small openings called spiracles, located behind their eyes, to take in water.

A southern stingray (*Dasyatis americana*) glides gracefully over a sandy ocean floor covered in fragments of shells. The stingray's flat, diamond-shaped body and long, whip-like tail are clearly visible. Its soft, muted coloration blends seamlessly with the substrate, providing effective camouflage. The stingray's eyes and spiracles are positioned on top of its body, adapted for its benthic lifestyle. The scene is serene, capturing the gentle movement of this marine creature in its natural habitat.

Milipede are arthropods are an Order of invertebrates included in the phylum Arthropoda, class Myriapoda. The body of this animal is cylindrical, the number of segments is around 25-100 and the number of legs is ± 224 or 112 pairs of legs, each segment only has one pair of legs and each abdomen has five pairs of legs and two pairs of spiracles. This animal reproduces by laying eggs. Generally, millipedes eat rotting plant remains. However, there are several species that are classified as carnivores. They swallow the food they find, extract the nutrients, then excrete the indigestible remains. This way of eating does not apply to several species that have a sucking mouth type. This fauna is found in abundance on the Raja Ampat islands, Papua.
