Do black widow spiders have spiracles?
Yes, that's how they get oxygen into their system. Some spiders also have a pair of book lungs. Black widows are included among them.
What gas do spiders breathe?
Spiders breathe in oxygen like humans do. They have small breathing holes called spiracles located on the underside of their abdomen that allow them to take in oxygen from the air.
How has a spider adapted to its environments?
Because spiders breathe through spiracles on their abdomen, they are able to breathe in air and smoke as they do not have any lungs
Do spider drink?
Spiders do not drink in the way mammals do, as they absorb water through their bodies using specialized structures called spiracles. They obtain water mainly through their prey or by absorbing moisture from their environment.
Why are spiracles important?
Function of spiracles for sharks
How is the respiratory system of a spider different from that of an insect?
Spiders have book lungs and a tracheae, while the Insect only has spiracles (air enters tiny branching tubules. AKA Tracheae)
Why do insects have spiracles?

Do crayfish have spiracles?
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.)
What kind of animals breathe through their stomata?
Insects and some spiders have specialized structures called spiracles that open and close to allow gas exchange through their bodies, including breathing in oxygen and releasing carbon dioxide. These spiracles are similar in function to stomata found in plants, but are specifically adapted for respiration in these animals.
Do arthropods have spiracles?
The larvae form of amphibians live in water and have gills. When they grow into their adult form they develop lungs. There are three orders of amphibians, Urodela, Anura and Apoda. Some Urodela (e.g Axolotls) retain their gills as adults, other orders do not.
How many spiracles does a butterfly have?
A butterfly has two spiracles, one on each side of its thorax. These spiracles are openings that allow the butterfly to take in oxygen for respiration.
What is the job of the spiracles on an insect?
The insect uses its spiracles to breathe through instead of their mouth.
