    LIFE CYCLE OF A JELLYFISH

    Fertilization: Like many other organisms, jellyfish are either male and produce sperm or female and produce eggs. When a male jellyfish is ready to mate, it releases sperm in the water through its mouth. When a female jellyfish passes by, these sperms get attached to her eggs. In her mouth, the process of fertilization occurs. Once the eggs are fertilized, they are either stored on the mother’s mouth or in brood pouches along her oral arms.

    Planula Larva: After the embryonic stage, the larvae hatch and get transformed into free-swimming planulae. A plunula has a small oval shape and has tiny hair on its surface that it beats together for movement. But, just like the adult jellyfish, most of its movements are entirely dependent on water tides and currents. Each planula floats around for a few days near the surface of the water and then sinks towards the ocean bottom.

    Polyp (scyphistoma): After a planula sinks to the bottom, it attaches itself to a hard stationary surface. This cylindrical planula is attached to the surface at its base; at its top is its mouth surrounded by a few tentacles which gather food. As this polyp grows, it begins to form new polyps from its trunk, forming a polyp hydroid colony. All the polyp members of this colony are attached to each other by tiny feeding tubes. These colonies are known to grow to very large sizes and can exist for a number of years. Only after the polyp colony has grown to an appropriate size, will the next stage of the life cycle of a jellyfish begin.

    Ephyra and Medusa: When the last stage is reached, the stalk of ployp begins to develop horizontal grooves. The topmost groove will free itself from the stalk as a baby jellyfish, known as ephyra. This ephyra will grow in size and become the adult jellyfish we all recognize. This last stage is the asexual reproduction aspect of the jellyfish’s life cycle.

  5. Deep Sea Fauna… with Googly Eyes, for science!

    Last week, I published my last research exploring the communities that live around hydrothermal vents in the Western Pacific. Check the succinctly named Comparative Population Structure of Two Deep-Sea Hydrothermal-Vent-Associated Decapods (Chorocaris sp. 2 and Munidopsis lauensis) from Southwestern Pacific Back-Arc Basins! If that’s a bit too dense for you, check out the summary over at my other blog:

    And learn about the incredible, delicate creatures that thrive at one of the planet’s most bizarre ecosystems.

  6. i never dreamed of even WANTING a tattoo until i met someone with nautilus shells on her hips and plans to get a Chrysaora colorata down her leg in September.
