Give the names of these gases. Answer: a. The chemical formula CH 4 indicates two types of atoms (C and H). A molecule of methane consists of 1 carbon atom and 4 hydrogen atoms. Similarly, SO 2 indicates two types of atoms (S and O). A molecule of sulfur dioxide consists of 1 sulfur atom and 2 oxygen atoms.
Mudskippers are a type of fish. They are part of a fish family known as tribe Periophthalmini), which is in the family, or type of, Gobiidae (Gobies). They are amphibious fish, which means that they can use their pectoral fins to walk on land.
The basic anatomical features for identification are illustrated in Figure 2. Most adult or subadult mudskippers can be easily discriminated to species level by examining a combination of characters (colouration patterns of the body and fins, and shape of the pelvic fins: Figures 2 and 3).However, these traits are not easily observed in a fish sitting on a stone in your tank.urprisingly perhaps, the adaptations mudskippers have for air breathing are not as complex as those seen in some other fish, such as lungfish or gouramis. Apparently air breathing hasn't played a major role in the evolution of mudskippers into amphibious fish able to operate successfully on land.
