not hop, it walks. Waxy monkey frogs are known for being calm, careful creatures.

(b) The Medusae as a Subordinate Individuality.
It has been shown above that polyps are budded only from polyps and that the medusae may be budded either from polyps or from medusae.
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.

Pelomedusa subrufa is found throughout Africa, as far west as Ghana, and south all the way to the Cape of Africa. It has also been recorded in parts of Madagascar, and is undistinguishable from those in east Africa.

To answer this question you need to understand that jellyfish actually go through two stages - a small polyp stage (a polyp is a shape like an anemone"a stalk, with a mouth surrounded by tentacles) and a medusa stage.
This sea is being "drained" by exotic species (cheat grass, medusahead, and Russian thistle or "tumbleweed") and native, but invasive trees (pinyon and juniper).

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, ...
Cnidarians have two basic body forms, medusa and polyp. Medusae, such as adult jellyfish, are free-swimming or floating. They usually have umbrella-shaped bodies and tetramerous (four-part) symmetry.
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.
Eventually, dozens of medusae — free swimming forms — break off the polyps and begin their journey to sexual maturity. The body of a jellyfish is bell-shaped with a mouth on the underside. Tentacles of varying lengths extend below.

On another visit, I found a small hydromedusa jellyfish, Polyorchis sp., which I had never seen before, in a pool.
Unlike other cnidarians, anthozoans do not have a medusa stage in their development. Instead, they release sperm and eggs that form a planula, which attaches to some substrate on which the cnidarian grows.
The African Helmeted Turtle (Pelomedusa subrufa) is a pleurodire.
Pleurodires hide their head sideways.

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.
The book covers six related species of frogs in the genera Phyllomedusa and Agalychnis, including the famous Red-eyed Leaf Frog (Agalychnis callidryas) pictured on the cover.
Specimens 8 feet wide have been found. In Sir Arthur Conan Doyle's story, "The Adventure of the Lion's Mane," Sherlock Holmes solves a homicide caused by contact between the victim and this medusa in a tidepool.
