Aquatic Leeches are segmented worms. Leeches have 34 body segments. These baby leeches have hatched from the cocoon. They are still attached to their mother. Leeches live in all freshwater habitats. They are more common in quiet water. Leeches suck the blood of fishes, amphibians, birds, and mammals.

Freshwater leeches (segmented worms) are important components of benthic communities in nearly every freshwater ecosystem. They are widely distributed, and some groups are found in great abundance. Several of the hirudinidan groups have been used for monitoring and detecting changes in water quality and physical habitats.

2010年6月21日 · The mother leech forms a tough, gelatinous cocoon around the egg mass and attaches it to a hard object or buries it in the mud. The cocoon contains all the nutrient that the young leeches need to survive, and the young emerge several weeks later. Some species nurture their young, which is unusual among annelids.

Macrobdella decora, also known as the North American medicinal leech, is a species of freshwater leech found in much of eastern North America in freshwater habitats, although there is one disjunct population in northern Mexico.

Here, we described a series of developmental stages of the W. pigra embryos and defined five broad stages of embryogenesis: cleavage stages, blastocyst stage, gastrula stage, organogenesis and refinement, juvenile.

Freshwater leeches are carnivorous predators that feed on small invertebrates like worms (470183-744), snails (470313-226), and insect larvae . They are also known for eating amphibian and fish eggs as well. Leeches can also be fed blood (rabbit, cow, or sheep). Put some blood in a Petri dish inside of a pan and introduce the leech to the pan.

Rhynchobdellida (from the Greek rhynchos, mouth, and bdellein, sucking), [1] the jawless leeches [citation needed] or freshwater leeches, [2] are an order of aquatic leeches. [3] [4] Despite the common name "freshwater leeches", species are found in both sea and fresh

They are also known for eating amphibian and fish eggs as well. Leeches can also be fed blood (rabbit, cow, or sheep). Put some blood in a Petri dish inside of a pan and introduce the leech to the pan.

Leeches are found in a variety of freshwater aquatic environments, including lakes, ponds, marshes, springs and slow streams. They are generally found in the area between the water’s edge and two meters depth, and prefer areas protected from wave action.
