وقال العلماء إن الـ3 أسماك من سلالات “E. Diskosomus” و”E. Scertlichensis” و”E. Minutus”، وتختلف عن بعضها بشكل الجمجمة وموقع الزعانف، وغيرها من المواصفات الجسدية، كما أن كلا منها كان قادر على التكيف مع الظروف البيئية على طريقته.

  80. Please let me know if you’re looking for a article author for
    your blog. You have some really great articles and I think I would be
    a good asset. If you ever want to take some of the load off,
    I’d absolutely love to write some content for your blog in exchange for a link back to mine.
    Please blast me an e-mail if interested. Many thanks!
