1. Gills: Mudskippers have gills just like other fish. When they are in water, they use their gills to breathe by extracting oxygen from the water.
2. Lungs: Mudskippers also have lungs, which are air-breathing organs. They can breathe air through their lungs when they are out of the water.
Mudskippers have a special organ called an opercular cavity that helps them breathe. The opercular cavity is a space behind the gills that can be opened or closed. When the mudskipper is in water, the opercular cavity is closed and the gills are exposed to the water. When the mudskipper is out of the water, the opercular cavity is open and the lungs are exposed to the air.
Mudskippers can survive out of water for long periods of time, but they need to return to the water regularly to breathe through their gills. They usually live in mangrove forests or other areas where they can easily access both water and land.
Mudskippers are fascinating creatures that have adapted to a unique lifestyle in the intertidal zone. They are a testament to the diversity and resilience of life on Earth.
