The larva develops into the hydroid stage of the lifecycle, a tiny sessile polyp called a scyphistoma. The scyphistoma reproduces asexually, producing similar polyps by budding, and then either transforming into a medusa, or budding several medusae off from its upper surface via a process called strobilation. The medusae are initially ...
Neck-formation: transverse constrictions appear near the upper extremity of the animal. A strobilating polyp is called a strobila while the non-strobilating polyp is called a scyphistoma or scyphopolyp. Segmentation: the number of constriction sites [jargon] increases and migrates down the body length, transforming the body into a sequence of ...
A larva (/ ˈ l ɑːr v ə /; pl.: larvae / ˈ l ɑːr v iː /) is a distinct juvenile form many animals undergo before metamorphosis into their next life stage. Animals with indirect development such as insects , some arachnids , amphibians , or cnidarians typically have a larval phase of their life cycle .

As bird flu continues to spread across the United States, questions have emerged about the risk of contracting the virus from milk and eggs.. More than 150 million poultry birds have been killed ...
A polyp in zoology is one of two forms found in the phylum Cnidaria, the other being the medusa. Polyps are roughly cylindrical in shape and elongated at the axis of the vase -shaped body. In solitary polyps, the aboral (opposite to oral) end is attached to the substrate by means of a disc-like holdfast called a pedal disc , while in colonies ...
The similar appearances of moon jellyfish is what has made them so hard to identify. They tend to have a variety of different sizes, however, they typically range 5–38 cm (2.0–15.0 in) in diameter with an average of 18 cm (7.1 in) wide and 8 cm (3.1 in) in height. [12]
The larvae stage is the most recognizable since it is at this stage O. fultoni emits its bioluminescent glow. The larvae stage usually lasts 6–9 months, depending on the availability of food. However, the glow worm can survive for long periods without eating. The larva is the only stage at which O. fultoni feeds. It eats primarily midges ...
