Spiracles and tracheae are vital adaptations that enable arachnids to breathe efficiently on land. Spiracles are small openings on the surface of their bodies that allow air to enter, while the tracheae are a network of internal tubes that transport oxygen directly to tissues and remove carbon dioxide. This system minimizes water loss, crucial for survival in terrestrial environments, and supports their metabolic needs. As a result, arachnids can thrive in diverse habitats, from deserts to forests.
No. The aquatic kind of spiracle (such as you'd find on rays and skates) could be located only on cartilaginous fish, or the most primitive of the bony fish. The loosest definition of spiracles seems to include a respiratory opening such as the blowhole in whales; lobsters do have ventral openings to the gills but these are anatomically dissimilar to those. (Also since lobsters are aquatic, they do not possess spiracles of the type you'd find on insects.)
Most arachnids live on land.
Fish breath little air particles in the water and kills separate the water from the air in the water but the air is not air that humans can breath its too thin
Why did the red land help the Egyptians for?
No. Like most land vertebrates lizard breath by pumping air into and out of their lungs through the nose. Caterpillars are insects and breathe by letting air passively circulate through spiracles in their sides.
No for arthropods; yes for some molluscs. The larger aquatic arthropods like lobsters and crabs accomplish gas exchange using gills. Smaller ones like the land-based insects have holes (spiracles) in the exoskeleton and a tube system to facilitate gas exchange necessary for respiration. In this case, unlike mammals which use lungs to oxgenate blood which is pumped to the tissues, the tracheal tubes from the spiracles deliver oxygen directly to the tissues. Aquatic molluscs have gills for gas exchange whereas molluscs adapted to live on land like snails do have a lung.
As the glaciers move over the land they help smash the land and also add silt and dirt to the ground.
on land , frogs breathe with the help of lungs , and in water , with the help of gills.

Marine crabs breathe underwater using gills, which are located in a two cavities under the carapace. True land crabs have enlarged, modified cavities that act like lungs so that the land crabs can breathe air
Only cultures help the Mayans the Spanish claimed the land killed Mayans and took control.
