These are composed of endoderm with a core of mesoglea and abundantly supplied with nematocysts. Numerous delicate gastric tentacles or phacellae are present on the floor of the gastric pouches. Stomach is produced into four inter-radial gastric pouches extending up to the half-way between the centre and the edge of the umbrella. Mouth leads into a short tube or gullet which opens into a centrally located stomach. Digestive Cavity and Canal System in Aurelia: Rhythmic contractions of muscles force water out from the sub-umbrellar cavity as a result the body is propelled in the opposite direction.ĥ. The coronal muscle helps Aurelia in its swimming movements, during which the ex-umbrella surface is kept upwards. Longitudinal muscles are present in the tentacles, manubrium and oral arms. The broad circular muscle band on the sub-umbrella surface is very strongly built and is known as coronal muscle. The muscular system in Aurelia is well developed. They occur on the oral arms, ex- and sub-umbrella surfaces, marginal tentacles and gastric filaments.Ĥ. Nematocysts are of three types - atrichous isorhiza, holotrichous isorhiza and heterotrichous micro-basic euryteles (Fig. The main difference lies in the structure of the mesoglea which contains fibres and loose amoeboid cells. Histologically, the scyphozoan medusa has the same organisation as that of Obelia. The gametes, when mature, break into the gastro-vascular cavity and pass to the outside through the mouth. In contrast to the usual ectodermal gonad in hydrozoans, the gonads in scyphozoans are endodermal. The gonads are coloured, horse-shoe shaped with a frill like structure and its concavity facing towards the mouth. Gonads are four in number, situated at the floor of the gastric pouches. The sub-genital pits are not connected with the reproductive system. It lies immediately beneath one of the gonads. 1.39).Īt a short distance from the mouth, at each inter-radial area, there is a somewhat circular aperture leading into a shallow pouch, the sub-genital pit (Fig.

Half way between the per-radii are the inter-radii and in-between the per-radii and inter-radii are the eight adradii (Fig. The corners of the mouth and the arms lie in the four per-radii, which are the major body axis. The oral arms are abundantly provided with stinging capsules or nematocysts. Each oral arm consists of a folded membrane, tapering to a point at its distal end and containing minute lobules along its edges. The corners of the mouth are drawn out into four lobes called oral arms. The velarium, quite unlike the true velum of the medusa of Obelia, contains gastro-dermal canals.Īt the centre of the sub-umbrella surface is the mouth, which is distinctly four- cornered and is borne at the end of an extremely short and inconspicuous manubrium. This is the velarium bearing the marginal notches and the fringe of marginal tentacles.

A narrow region of the umbrella, close to the edge, is very thin and flexible.

At the centre of two rhopalial lappets is present the rhopalium covered by a hood.īetween the pairs of lappets the edge of the umbrella is provided with numerous closely set marginal tentacles. The outline of the umbrella is somewhat circular, but is broken by eight equidistant notches, each bearing a pair of delicate sense organs, the marginal lappets or rhopalial lappets. The jelly like transparent umbrella shaped body has four, red or purple horse-shoe shaped gonads on its upper surface and form long and narrow oral lobes hanging downwards from lower surface. However, the concave and convex sides of the umbrella are more pronounced. I should program a DAW that is for engineering ear training only, so you can practice with your favorite plugins and parameter randomisation, track selection etc.Adult Aurelia is like a large version of the medusa of Obelia (Fig.

I want to make my own training routine before trying paid stuff but I'm kind of clueless on how to start

I am currently gathering all kinds of exercises and info's on that topic and I've stumbled upon a website that looks professional and systematic, its called Soundgym, have you guys tested the pro membership, is it worth it?
