Leaf Sheep, An Underwater Treasure That Can Photosynthesize


This little sea slug – known as the leaf sheep or also known by their scientific name – Costasiella kuroshimae has the unusual ability to photosynthesize. They are one of the only sea creatures in the world that can perform photosynthesis.



They graze on green algae. When they consume the algae, they retain the chloroplast, a plastid that contains chlorophyll. The chloroplast is then stored in their bodies and can be used for photosynthesis.






The look of this sea slug makes it stand out among anything else around it. It has two beady eyes and antennae that look similar to that of sheep’s ears. They range in size from 5 millimetres (0.20 in) to 1 centimetre (0.39 in) in length can be found near Japan, Indonesia, and the Philippines.
