Final answer:
Describing the size of a fish using detailed measurements and comparisons helps in visualizing the fish more accurately than anecdotal estimates. The size of fish varies widely from the massive whale shark to tiny species like the stout infantfish. For precise descriptions, scientific methods like using a spring scale are used.
Step-by-step explanation:
When describing the size of a fish, it is often given in simple, rounded measures to facilitate communication and comprehension. For example, instead of stating 8 pounds 11 ounces, one might say the fish weighs about ten pounds, which is considered "close enough" for most storytelling purposes. However, for scientific accuracy or regulation purposes, precise measurements are required.
In biology, the size of fish is varied, ranging from the large 65-foot, 75,000 pound whale shark to minute species like the stout infantfish at 0.33 inches. Descriptions can help in visualizing these fish, especially when detailed measurements, comparisons, and visual traits (like the appearance of scales on a blue Siamese fighting fish) are provided. This level of detail not only makes the fish easier to visualize but also provides insight into their adaptations, such as the streamlined skin important for efficient swimming.
For the purpose of scientific study or record-keeping, measures like mass, which can be established by using a spring scale, play a significant role. This method offers a more accurate description of a fish's weight compared to anecdotal estimates by fishermen.
