FAQs on Class 6 Science - Body Movements Movement in Fish and Snakes

1. How do fish move in water?
Ans. Fish move in water by using their fins and tails. The fins help them to maintain balance and change direction, while the tail propels them forward by creating a side-to-side motion.
2. Do all snakes move in the same way?
Ans. No, not all snakes move in the same way. Most snakes move by contracting and extending their muscles in a wave-like motion, which is called serpentine movement. However, some snakes, like the sidewinder snake, move by a unique sideways motion, while others, like the python, move by gripping objects with their scales.
3. How do fish and snakes adapt their movement to different environments?
Ans. Fish and snakes have adapted their movement to different environments in various ways. Fish have evolved different types of fins and tails depending on their habitat. For example, fish living in fast-flowing water may have streamlined bodies and powerful tails to help them swim against the current. Snakes, on the other hand, have adapted their movement to different terrains. Some snakes have developed specialized scales or body structures to climb trees, swim in water, or move across sandy or rocky surfaces.
4. Can fish and snakes move on land?
Ans. While fish are primarily adapted for movement in water, some species of fish, such as mudskippers, have the ability to move on land. They use their pectoral fins to "walk" or "skip" on the muddy surfaces. On the other hand, most snakes are capable of moving on land, although their movement may be slower and less efficient compared to their movement in water or on their preferred habitat.
5. How do fish and snakes navigate their surroundings while moving?
Ans. Fish and snakes use various methods to navigate their surroundings while moving. Fish rely on their senses, such as vision, lateral line system (which detects changes in water pressure), and the sense of smell, to detect obstacles, prey, or potential predators. Snakes primarily use their sense of smell and their ability to detect vibrations through their lower jaw to navigate their surroundings. They also have heat-sensing organs, called pit organs, which help them locate warm-blooded prey.
