Modern Text Book of Zoology: Invertebrates
The larva now looks like a trumpet-shaped polyp or Hydra, and is called
hydratuba or young scyphistoma (Gr., skyphos, cup+stoma, mouth). Endoderm of
its enteric cavity is raised into four interradial longitudinal gastric ridges or
taenioles, ...
Upon settling on the substratum, it develops into the scyphozoan polyp, the
scyphistoma. It is a tiny, trumpet-shaped, asexual and sessile, feeds and
produces scyphistomae asexually from the stolons. It is attached to the
substratum by its ...

A Functional Biology of Scyphozoa
The extent of the amoebocyte migration and the extent of the breakdown or
participation of the aboral epidermis of the parent scyphistoma are varied. Prior to
podocyst formation the pedal disc contains desmo- cytes, cells which form protein
...

Primordial Germ Cells in the Invertebrates: From Epigenesis ...
After attachment to a substrate, a 'scyphistoma' polyp is formed, which may
produce 'ephyra' medusoids by mono- or poly-disc strobilation. Eggs
intermediate in size and yolk content have only a very transient planula stage
and develop more ...

opposite tentacles first make their appearance ; not, however, simultaneously, the
one appearing after the other, so that the young larva about to develop into the
Scyphistoma presents a bilaterally symmetrical structure. Subsequently the ...

Now it develops into a little polypoid larva-the scyphistoma. The scyphistoma
looks like a Hydra. It feeds and produces new scyphistomae by asexual budding.
At certain periods of the year, medusae formation occurs by transverse fission of
...

The Masterpiece of Nature: The Evolution and Genetics of ...
The budding of hydrozoans and the fission of anthozoans are two of the three
major modes of asexual reproduction in coelenterates: the third is the transverse
division of the scyphistoma larvae of scyphozoans, a process known as
strobilation ...

Biology of Coelenterata
This develops into a typical Scyphistoma larva of a trumpet form with basal stalk,
pedal disc and expanded oral end with mouth, manubrium and tentacles. The
mouth breaks through at the side of the closed blastopore. The first tentacles are
...

An Introduction to Zoology
Fertilization and development may occur in the seawater, or the fertilized eggs
may be brooded on the oral arms. In either case a planula larva develops. The
planula larva transforms into a polypoid larval stage, called a scyphistoma, which
is ...
