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.
Jellyfish primarily eat plankton, which are organisms that lack the strength and size to swim and therefore drift in marine and freshwater currents. Larger species of jellyfish also eat crustaceans, fish and other jellyfish. Jellyfish are carnivorous and primarily feed on animals.
