bioluminescentoceangoddess: Pink HelmetAglantha digitaleThe Pink Helmet is a mini hydromedusa that comes in a variety of vibrant colors. The tiny jelly is only 4 cm in size and is found towards the surface of the ocean. The purple and blue hues we see in its bell are caused by a phenomenon known as iridescence, when light strikes the jelly’s thin tissue at different angles (similar to what we see in a soap bubbles). It also has orange pigmentation near its mouth; this pigmentation helps attract prey and mask luminescence. Furthermore, females tend to be more colorful than males.Photo credit: https://biolum.eemb.ucsb.edu/organism/pictures/aglantha.html https://www.pinterest.com/pin/186899453255850798/ -- source link
