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 ...
Generally, there is no other opening to the body except the mouth, but in some cases excretory pores are known to occur in the foot, and pores may occur at the tips of the tentacles.

[5] They may invade open wounds and lesions or unbroken skin. Some enter the body through the nose or ...
Scientists discovered a 520-million-year-old fossilized larva with brains and guts intact, offering unprecedented insights into early arthropod evolution.
Late medieval gothic plate armour with list of elements. The slot in the helmet is called an occularium. This list identifies various pieces of body armour worn from the medieval to early modern period in the Western world, mostly plate but some mail armour, arranged by the part of body that is protected and roughly by date.
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. ... They typically appear in specific ...
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 ...
