A tube-like gadget called a spacer can help kids or people with trouble breathing use an HFA more easily. Dry powder inhalers (DPIs) require you to breathe in quickly and deeply. That can make them hard to use during an asthma attack when you canât fully catch a deep breath.
Some jellyfish are clear and can look like a plastic bag in the water. Others are in vibrant colors such as pink, yellow, blue, and purple, and often are luminescent.
Some jellyfish are harmless, others have a relatively mild sting, and some creatures look like jellyfish but really are not. Two jellyfish in particular, the Portuguese Man of War, and the box jellyfish (both pictured above) can give a very painful sting.
