Description | ফুসফুস মাছের উৎপত্তি প্রায় 40 থেকে 30 কোটি বছর আগে। ফুসফুস কয়েক শ্রেণীর মাছের মধ্যে পাওয়া গেলেও বর্তমানে অবশ্য ডিপনয় শ্রেণীই প্রধান। এই জাতের মাছের পট্কার মধ্যে ফুসফুসের আবির্ভাবের ফলে তাদের শসন পদ্ধতি বদলায়, তারা প্রয়োজনীয় অক্সিজেন জল ছাড়াও বাতাস থেকে সংগ্রহ করার ক্ষমতা রাখে। এই প্রবন্ধে ডিপনয় শ্রেণীর ফুসফুস মাছের গঠন, আকৃতি ও প্রকৃতি সম্বন্ধে আলোচনা করা হয়েছে। Lung fish originated about 40 to 300 million years ago. The lungs are found in a few species of fish, but at present the Diponay class is predominant. The appearance of the lungs in this species of fish changes the way they move, giving them the ability to collect the necessary oxygen from the air in addition to water. This article discusses the structure, shape and nature of Diponay class lung fish. |
