Chironex fleckeri, also known as box jellyfish, lives in and around the waters of Australia and Southeast Asia. They inhabit parts of the Indian Ocean, Pacific Ocean, and the Great Barrier Reef. Box jellyfish have been found in the waters on the western coast of Australia in the Exmouth Gulf to Gladstone in the northern waters of Australia.Jellyfish Evolution. ellyfish evolution. Medusae were the earliest animals to evolve muscle-powered swimming in the seas. Although medusae have achieved diverse and prominent ecological roles throughout the world’s oceans, their primitive organization of muscle tissue limits their mechanical alternatives for swimming (see Nemopsis study below).Dec 17, 2018 · Jellyfish were probably the first muscle-powered swimmers in the open ocean. They appeared in the late Precambrian Era, a period of major geologic and ecological changes that preceded the Cambrian explosion of animal life. At some point in their evolution, jellyfish gained the ability to transition from a stationary polyp to a swimming medusa. Jellyfish blooms have become a marine environmental issue with detrimental effects on marine ecosystems around the world.

Jellyfish regeneration involves a combination of cellular processes underlying wound healing, blastema formation, and systemic patterning that require organ or body-level communications. The evolutionally conserved wound closure mechanisms necessitate epithelial tissue repair upon injury.

Jellyfish Evolution and Species Jellyfish have a long and fascinating evolutionary history. The first jellyfish-like creatures appeared over 500 million years ago during the Cambrian period. (K. Raskoff, Monterey Peninsula College, Hidden Ocean 2005, NOAA) While jellyfish and comb jellies have several anatomical differences, the basics are the same. Both have two major cell layers: the external epidermis and the internal gastrodermis.Jan 8, 2019 · Jellyfish didn’t need novel genes to take an evolutionary leap in complexity. A moon jellyfish from the Aurelia genus swims freely in its medusa life stage, which is a novelty among the group of organisms called cnidarians.
