clitellum

Together, they form the clitellum, which is important in reproduction.

Occasionally, living segments of the worm will be shed with the clitellum.

The clitellum is a band of grandular tissue present on segments 14 to 16.

The clitellum becomes very reddish to pinkish in color.

To form a cocoon for its eggs, the clitellum secretes a viscous fluid.

During reproduction, the clitellum secretes a coat which hardens.

Like other oligochaetes, such as earthworms, leeches share a clitellum and are hermaphrodites.

Similar to the earthworms, leeches also use a clitellum to hold their eggs and secrete the cocoon.

The clitellum is a thick, saddle-like, ring found in the epidermis (skin) of the worm, usually with a light-colored pigment.

The megadriles are characterized by having a distinct clitellum (which is more extensive than that of microdriles) and a vascular system with true capillaries.

Adult earthworms develop a belt-like glandular swelling, called the clitellum, which covers several segments toward the front part of the animal.

The clitellum becomes apparent in mature annelids, but may be hard to locate visually in younger annelids.

Lumbricus castaneus varies from chesnut to violet brown; brown or yellow ventrally, and has an orange clitellum.

Some time after copulation, long after the worms have separated, the clitellum (behind the spermathecae) secretes the cocoon which forms a ring around the worm.

The Clitellata are a class of annelid worms, characterized by having a clitellum - the 'collar' that forms a reproductive cocoon during part of their life cycles.

The clitellum is a thickened glandular section of the body wall in earthworms and leeches, that secretes a viscid sac in which the eggs are deposited.

A clitellum is part of a of the reproductive system of clitellates, a subgroup of annelids which contains oligochaetes (earthworms) and hirudineans (leeches).

In all the body segments except the first, last and clitellum, there is a ring of S-shaped setae embedded in the epidermal pit of each segment (perichaetine).

They are true earthworms, having a complex vascular system with capillaries, the male pores (on 15 or 13) behind the female pores (on 14) and a multicelled clitellum.

Technically speaking, I suppose it was a Melaquinworm, but it looked like an earthworm to me: brown, annelid, roughly ten centimeters long, with the familiar thick clitellum band partway along its body.

The segmentation of Lumbricus rubellus identifies the organism as a member of Phylum Annelida, while the enlarged segments towards the anterior of the organism called the clitellum denotes membership to Class Clitellata.

However, they have a unique reproductive organ, the ring-shaped clitellum ("pack saddle") round their bodies, which produces a cocoon that stores and nourishes fertilized eggs until they hatch or, in moniligastrids, yolky eggs that provide nutrition for the embyros .
