Insects breath through them.
Insects, generally, breath through spiracles, usually on their abdomen.
Since only Arthropoda have spiracles that would mean that the only sea creatures that breath through them would be CRUSTACEANS
Like all insects they have spiracles along the sides of their bodies.
ants breath through their spiracles which are found on the abdomen of the ant
grasshopper, insects. Insects have tiny air holes on their bodies called spiracles to breathe.
Some vertebrates eg. sharks and stingrays and some arthropods eg. the indian moon moth and the cricket.
The spiracles and trachea are structures that enable respiration in insects. Air enters the body through the spiracles and then travels through the trachea. Spiracles are tiny holes in an insect's exoskeleton, and the trachea is a network of tubes.
grasshoppers breath through spiracles
Insects take in oxygen through tiny openings in their bodies called spiracles. These spiracles are connected to a network of tubes called tracheae, which deliver oxygen directly to their cells.
They exchange them through spiracles.
Praying Mantis are insects, they do not have lungs (gas exchanges happens using spiracles) so they can not hold their breath.
