animals that breathe through moist skin book lungs and book lungs.
They don't physically breathe in & out - like animals an people. They have no diaphragm to pull air into their lungs. The spiders lungs are simple 'book lungs' which simply exchange gasses.
Black widows breathe through small openings on the underside of their abdomen called spiracles, which allow air to enter their respiratory system. They do not have lungs; instead, they have book lungs that help them exchange gases.
They use either what's known as trachea, or what's similar to gills, book lungs.
Most animals breathe throught there mouth and nose. Other animals like Whales, Dolphins,. etc. breathe through air holes. Water animals, breathe water through gills. and often suface for oxygen.(Again through mouth or air hole; depending on the animal.)
All animals have different types of breathing, as of their different sized lungs and heart, and the rate in which the blood pumps and the size of the animal with the size of the breath taken into their lungs, which causes quicker or slower paces of breath.If that makes sense.
With introverted branchial appendages of the abdomen called book lungs.
Arachnids have respiratory structures called 'Book Lungs', however they in no way resemble the lungs in a mammal. Instead, they are folded sheets of thin tissue that allow gases to be exchanged with the environment.
A ladybug is considered a land arthropod along with arachnids and other insects. Arachnids (like spiders & scorpians) breathe through things called book lungs and other arthropods have well adapted organs for sight, sound, touch, and breathing. So-long story short, Ladybugs breathe through their well adapted organs for getting air.For more information, I'd search for how insects breathe or do insects have lungs. :) Hope this helped!
Spiders have one of two types of lungs. The first is called a book lung, where there are stacks of lamellae that absorb oxygen as it passes through them. The second uses openings in the chitin called spiracles that air passes through and gas exchange occurs.
Grasshoppers as well as other insects have a tracheal system instead of a respiratory system to move gases. A respiratory system requires energy to move the gases where as the tracheal system uses a process of simple diffusion which does not use any energy.
Ticks have an air hole called spiracles on the back side of its body close to its hind legs. This allows it to breathe when its mouth is submerged into the skin. Actually, the skin swells to expand the head.
