Answer 2

Fastest Swimming Fish:

The fastest swimming fish are known to inhabit the open waters. Some examples of fast-swimming fish include tuna, marlins, and sailfish. These fish are built for speed and have streamlined bodies that allow them to move quickly through the water. They also have powerful tails and fins that help propel them forward. Tuna, for example, are known for their speed and can reach speeds of up to 75 kilometers per hour (47 miles per hour) [[1]].

Fish Hearing:

Fish have a unique sensory system for detecting sound and vibrations in the water. While they do not have external ears like humans, they do have an inner ear that allows them to perceive sound. The inner ear of fish is responsible for detecting sound waves and transmitting them to the brain for processing. Some fish species also have a specialized structure called the swim bladder, which can help them detect sound and vibrations in the water [[2]].

Human Consumption of Commercial Fish:

Humans obtain various resources from commercially fished species of fish. These resources include minerals, fertilizers, vitamins, glue, and even pearls. Fish are a valuable source of nutrients and are consumed by humans worldwide. They provide essential vitamins and minerals, such as omega-3 fatty acids, which are beneficial for human health [[3]].

Human Activities Impacting Fish in Natural Water Bodies:

Human activities can have negative impacts on fish populations in natural water bodies. Some of these activities include gravel extraction from the bottom of water bodies, the presence of predators that feed on fish, logging activities that can lead to increased sedimentation in rivers, car washing that releases pollutants into water bodies, and the runoff of fertilizers from fields into water bodies. These activities can disrupt fish habitats, affect water quality, and ultimately harm fish populations [[4]].

Organ Systems Absent in Fish:

Fish have a well-developed nervous system, including a brain, which allows them to process information and respond to their environment. However, fish lack certain organ systems that are present in other animals. For example, fish do not have a skeletal system that includes bones and a spinal column. Instead, they have a cartilaginous structure that provides support and flexibility. Additionally, fish do not have a respiratory system that includes lungs like mammals do. Instead, they have gills that allow them to extract oxygen from the water [[5]].
