Photomicrography of Hydra The Canadian Nature Photographer
Structure of Hydra: Hydra has a slender tubular body and exhibits distinct radial symmetry (Fig. 12.2). The body is extremely contractile and the length varies from 10 to 30 mm. The lower end of the tubular body is closed and this side is designated as the aboral or proximal end. This end of the body is named as the foot or basal disc which is.

The hydra resembles a slender sea anemone. At the top of the organism is a number of tentacles arranged in a circle around the hydra's mouth. These tentacles are controlled by a simple neural net. Tiny stinging cells, called nematocysts, cover the tentacles. While harmless to humans, these cells can incapacitate the tiny organisms the hydra eats.

Hydra, in Greek legend, the offspring of Typhon and Echidna (according to the early Greek poet Hesiod 's Theogony ), a gigantic water-snake-like monster with nine heads (the number varies), one of which was immortal.
Hydra Biology, Classification, Characteristics, and Reproduction
The body wall is comprised of two layers of cells separated by a thin, structureless layer of connective tissue called the mesoglea and the enteron, a cavity containing intestinal organs. The lower end of the body is closed, and an opening at the upper end both ingests food and ejects residue.

Does Hydra have tissues and organs? Hydra has reached the tissue grade of organization, but it lacks organs. It consists of a tube about 5 mm long formed by two epithelial layers (endoderm and ectoderm). It has a head consisting of a mouth surrounded by a ring of tentacles at one end and an adherent disk, the foot, at the other end.

The body wall of Hydra is organized as an epithelial bilayer (ectoderm and endoderm) with an intervening extracellular matrix (ECM), termed mesoglea by early biologists. Morphological studies have determined that Hydra ECM is composed of two basal lamina layers positioned at the base of each epithelial layer with an intervening interstitial matrix.
