Jellyfish Eyes was released on Blu-ray in Japan by Toho on January 24, 2014. [14] On June 24, 2015, American art house distributor Janus Films acquired the rights to distribute Jellyfish Eyes in North America, which was then released on July 15, 2015. [15]
The study of jellyfish eye evolution is an intermediary to a better understanding of how visual systems evolved on Earth. [40] Jellyfish exhibit immense variation in visual systems ranging from photoreceptive cell patches seen in simple photoreceptive systems to more derived complex eyes seen in box jellyfish. [40]
Each rhopalium carries six eyes of four morphological types (lower lens eye LLE, upper lens eye ULE, pit eye PE and slit eye SE) and a light sensitive neuropil (NP, red broken line). The eyes are responsible for the image formation in the animal and the light sensitive neuropil is thought to be involved in diurnal activity".
Polyorchis, or bell jellies, is a genus of hydrozoans in the family Corynidae. They are transparent with red coloration in their internal organs and eye spots around the rim of their bell.
Whereas some other jellyfish have simple pigment-cup ocelli, box jellyfish are unique in the possession of true eyes, complete with retinas, corneas and lenses. [13] Their eyes are set in clusters at the ends of sensory structures called rhopalia which are connected to their ring nerve. Each rhopalium contains two image-forming lens eyes.
Eyes and other sensory organs probably evolved before the brain: There is no need for an information-processing organ (brain) before there is information to process. [21] A living example are cubozoan jellyfish that possess eyes comparable to vertebrate and cephalopod camera eyes despite lacking a brain. [22]
Tripedalia has an advanced eye structure making it an efficient hunter and navigator within mangrove habitats. [7] Box jellyfish have 24 eyes that are categorized into four morphological types. These four types are made up of two pigment cup eyes and two lens eyes that enhance the jellyfish’s ability to navigate their environment and detect ...
Pacific sea nettles, Chrysaora fuscescens. Cnidaria (/ n ɪ ˈ d ɛər i ə, n aɪ-/ nih-DAIR-ee-ə, NY-) [4] is a phylum under kingdom Animalia containing over 11,000 species [5] of aquatic invertebrates found both in fresh water and marine environments (predominantly the latter), including jellyfish, hydroids, sea anemones, corals and some of the smallest marine parasites.
