In cnidarians, a medusa is a body form that is often free living. They can vary from being bell-shaped to the shape of a thin disk. The upper surface is called the exumbrella and the lower surface the subumbrella.

Phyllomedusa vaillantii — White-lined Monkey Frog
Some other names for this species:
Sharp-nosed Monkey Frog, Spotted Monkey Treefrog, White-lined Leaf Frog, Razor-backed Monkey Treefrog, White-lipped Monkey Frog ...

Breeding: Little is currently published about the courtship and breeding of Hydromedusa. They have, however, been bred in outdoor ponds by keepers in their country of origin and should prove to be straightforward to breed in captivity once acclimated to their new environments.

Medusa (pl. medusae):
Adult umbrella- or bellshaped forms of jellyfish, with mouth facing downward.

Medusae are usually bell-shaped animals with a concave oral surface, or mouth, and tentacles that dangle downward from the rim of an umbrella-like body.
Four classes make up the phylum Cnidaria: ...

The last animals in our tour of the deep is this deep sea medusa, a relative of the jellyfish. It captures prey with its tentacles and digests is in its central cavity, shown here in red.

Scientific Name:
Phyllomedusa sauvagii
: Phyllomedusa sauvagii males and females range from five to eight cm in length, with the females usually being about 25% larger than the males. Their common name describes them perfectly.

Seeds of medusahead (Taeniatherum caput-medusae) were not used by Great Basin pocket mice in Lassen County, California, and areas with heavy medusahead invasion were avoided [29]. Estimated seed intake of a Great Basin pocket mouse is from 4 to 10 percent of total body weight daily.

Theoretically, members of Cnidaria have life cycles that alternate between two forms-asexual polyps (the body as a vase-shaped form), and sexual, free-swimming forms called medusae (singular medusa; the body in a bell-shaped form).

Cnidarians exhibit two basic structural forms, a medusa and a polyp. The medusa form is a free-swimming structure which consists of an umbrella-shaped body (called a bell), a fringe of tentacles that hang from the edge of the bell, a mouth opening located on the underside of the bell, ...

They have two body shapes: the medusa (a jellyfish-like swimming form) and the polyp (a sea anemone-like sessile or static form). During their life cycle they may transform themselves from one shape to the other. All cnidarians possess stinging cells, which they use to kill or paralyse prey.

Eight clublike oral arms that each contain several mouths transport food to the jelly's stomach. As with all true jellies, blue jellies alternate between a sexual medusa stage and an asexual polyp stage. Adult medusae brood their fertilized eggs and the resulting planula larvae.

The Golden Leaf Folding Frog (Phyllomedusa sauvagii) - these frogs are very common in the African savanna.
Golden Leaf Folding Frogs have the unusual habit of eating other frogs eggs and larvae by raiding frog nests.

Scientific name: Phyllomedusa sauvagii
Range: The Chacoan region of Bolivia, Northern Paraguay, MatoGrosso do Sul (Brazil), and Northern Argentina
Habitat: Rain forest ...

Unlike other cnidarians, anemones (and other anthozoans) entirely lack the free-swimming medusa stage of the life cycle: the polyp produces eggs and sperm, and the fertilized egg develops into a planula that develops directly into another polyp.
