Biology Of the 650 species of leech listed, Hirudo medicinalis is one of the most extensively studied. This annelid from the subclass Hirudinea has 2 suckers, one housing the mouth and its 3 jaws. It lives mainly in the stagnant waters of marshes and ponds. When it comes to reproduction, the animal is a hermaphrodite. Inseminated leeches lay their eggs during the spring and summer months, outside the water, with cocoons containing as many as thirty young.

Hirudinea Leeches are famous as blood-suckers. The species that feed on blood have special chemicals in their saliva that prevents blood-clotting. Many blood-feeding leeches attack only fish, a few attack any vertebrate (including people), and a few are specialists on another group of animals, like turtles or waterbirds.

What are Annelids? Annelids can also reproduce sexually. There are four classes of annelids: polychaete worms, marine annelids which make up the majority of all species (more than 10,000), clitellates, a large group which includes leeches and earthworms, haplodrils, simple marine worms, and myzostomids, small parasites of sea lilies.

Annelida: Life History and Ecology Most earthworms and leeches are hermaphroditic with both male and female gonads. Polychaetes usually have separate sexes; many polychaetes hatch into a particular type of planktonic larva, the trochophore, which later metamorphoses into a juvenile annelid. Some polychaetes, however, can reproduce asexually, by budding.

Annelid A major invertebrate phylum of the animal kingdom, the annelids number more than 9,000 species distributed among three classes: the marine worms (Polychaeta), which are divided into free-moving and sedentary, or tube-dwelling, forms; the earthworms (Oligochaeta); and the leeches (Hirudinea).

What are some fish that eat leeches? Best Answer: Most fish that are larger than the leech will ATTEMPT to eat it... they are considerably tougher skinned than an earthworm,and earthworms can't attach back like a leech. Two types of fish can ACTUALLY eat a leech.... those that can have leeches in their natural diet (so they are evolved to eat/digest them) and those that chew their food (cichlids come to mind,also some catfish). Leeches are also more tender when younger,so some fish feed on them then,but not later....

Understanding the leech While leeches are confident swimmers, they are not exceedingly fast, typically covering about a foot every few seconds (check out the video at the bottom for an example of a swimming leech). This type of motion is often most well imitated using a slow retrieve and a fly with a weighted head.

Common Examples of Annelids Leeches. Often feared for their reputation as bloodsuckers, leeches are another example of annelids common throughout the world. Most live in temperate climates, but some are found in other places, ranging from hot desert ponds to the icy waters of Antarctica.arthworms are probably the best known and most common of the annelids; more than 2,700 kinds of earthworms have been identified around the world. They range from no more than a half-inch long to many feet long; the largest recorded earthworm was 22 feet.

Annelid Leeches have 34 segments, and elongation occurs by the subdivision of these segments. Leeches have a small sucker at the anterior end and a large sucker at the posterior end. A clitellum is present in the mid-region during the reproductive period. The poorly developed eyes are paired structures at the anterior end.

- (Erpobdella obscura) Fishing with Ribbon leeches is very popular in the northern part of the United States. In Wisconsin there are several species of fish like walleyes, bass, perch, bluegill, and crappie that seem to like eating leeches. Some anglers swear by leeches and say they are the only thing thats working. Leeches are a great alternative to nightcrawlers. All leeches have 2 sucking discs (one at each end).

Ch 27 Worms and Mollusks Oligochaetes have steamed lined bodies and few setae compared to polychaetes and most of them live in fresh water or soil. Leeches are typically external parasites that suck the blood and body fluids of their host. Polychaetes are marine annelids that have paired, paddlelike appendages tipped with setae. Describe the feeding strategies of earthworms and leeches. Worms collect food by extending itss pharyna and pressing it agianst the surrounding sediments.

- It lives in lakes, marshes, and slow-moving streams. This leech is brownish-green with black and red spots, and it has a round, sucker-shaped mouth. They also have five pairs of eyes. The Freshwater Leech is a parasite that feeds on the blood of fish, frogs, turtles, and mammals.

Leeks, Size Does Matter!â¦ and so does shape. First off, there are lot’s of leek varieties out there. There seem to be two basic classifications of leeks, tall and short. Not all the tall leeks are skinny and not all the short leeks are fat, but it seems to tend that way as if the plant had only so much to grow and was guided either out or up.

Annelids - Annelida Marine species are members of one of two classes, Polychaeta (Polychaete worms) or Hirudinea (leeches). A third class, Oligochaeta, includes the well-known earthworms. The phylum is up for a revision as recent research has revealed that the leeches should probably join the oligochaetes, together with the earthworms.o, the annelids now inlcude both segmented and unsegmented worms. They come in a huge variety of shapes and colors. Many of the worms live their lives buried in the sand while others stand up like flowers. Some are microscopic in size, others can reach a length of 3 meters.

- Marine worms come in a staggering variety of forms. New forms are being discovered all the time and here we can only look at a few selected examples. We begin with the polychaetes (btistle worms). Polychaetes, like the earthworms are segmented (annelid) worms. Earthworms, leeches and some freshwater worms belong to a group called the oligochaetes, since they have only a few spines (chaetae) per segment.
