unlike human beings, most fishes continue to grow as long as they live. old fish may become very large. the exceptions are fish such as the salmon, which have a definite period of growth before spawning and, after spawning, die. carp are said to have a life span of 100 years, but few fish in the wild die of old age. though many fishes are believed to reach ages of 50 to 100 years, scientific documentation for individuals reaching ages beyond 15 to 20 years in natural environments is rare.이 지문 해석좀 도와주세요. 특히 마지막 문장이 참..매끄럽게 되질 않아요..ㅜㅜ
