ما نوع السمك الذى يضيء فى البحر ولماذا يضيء؟

هي سمكة أبو شص المعروفة بالانجليزية باسم Angler fish.

أما سبب الإضاءة فهو استدراج الفريسة في عمق البحر إليها ، حيث أنها تعيش في أدنى البحر مما يجعلها منطقة معتمة للغاية ووجود ضوء يجلب كائنات إليها أما كيف تكون هذه الإضاءة فهي بسبب علاقة تعايش وتكافل بينها وبين أنواع من البكتيريا تعيش على سطح جسمها.

وتكون الإضاءة ناتجة عن تراكم البكتيريا بشكل كبير جداً على شكل مستعمرة فوق جسم السمكة بشكل يعطيها هذه الإضاءة.
