Aurelia undergoes alternation of generations, whereby the sexually-reproducing pelagic medusa stage is either male or female, and the benthic polyp stage reproduces asexually. Meanwhile, life cycle reversal, in which polyps are formed directly from juvenile and sexually mature medusae or their fragments, was also observed in Aurelia coerulea ...
In those scyphozoans that have the larval planula metamorphose into a polyp, the polyp, also called a "scyphistoma," grows until it develops a stack of plate-like medusae that pinch off and swim away in a process known as strobilation. Once strobilation is complete, the polyp may die, or regenerate itself to repeat the process again later.
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 ...
Maggot therapy (also known as larval therapy) is a type of biotherapy involving the introduction of live, disinfected maggots (fly larvae) into non-healing skin and soft-tissue wounds of a human or other animal for the purpose of cleaning out the necrotic (dead) tissue within a wound (debridement), and disinfection. There is evidence that ...
Here are tips and photos to help you determine if your rash is actually chigger bites. Chiggers are tiny larvae that bite skin and cause itchy, red bumps. Here are tips and photos to help you ...
The male flies compete with wild breed males for females to copulate and thus cause females to lay batches of unfertilized eggs that cannot develop into the larval stage. [citation needed] One prevention method involves removing the environment most favourable to the flies, such as by removal of the tail.
Aurelia aurita (also called the common jellyfish, moon jellyfish, moon jelly or saucer jelly) is a species of the family Ulmaridae. [1] [2] All species in the genus are very similar, and it is difficult to identify Aurelia medusae without genetic sampling; [3] most of what follows applies equally to all species of the genus.
Jeanne Vaccaro, a scholar and curator from Kansas, always wanted to become a bumper sticker person. For years, she collected stickers from artists, musicians and bookstores, but she kept them away ...
