Question

Similarity between the arrangement of chaetae in an oligochaetes and polychates

Answer 1

Answer:

Annelida: Oligochaeta

Portrayal

Oligochaetes are sectioned, respectively balanced worms with decreasing closures. There is a front prostomium, trailed by the principal portion, the peristomium, which conveys the ventral mouth. The back limit is the pygidium, with terminal rear-end. Different fragments are comparable in structure aside from a gathering of up to 6 portions in the genital locale which structure a thickened misty clitellum in explicitly develop examples. Chaetae are regularly present in two sets of groups for each fragment. Chaetae incorporate both hair-like vessels and basic or distally-toothed snares. Compound chaetae are missing.

Comments

• The Oligochaeta incorporates the terestrial worms and an a lot more noteworthy assorted variety of littler freshwater, estuarine and marine species. Generally marine and freshwater oligochaetes have a place with one of 3 families: Naididae, Enchytraeidae or Tubificidae.

• A few oligochaetes are effectively mistaken for polychaetes, yet oligochaete snares are unmistakable and are never hooded as in numerous polychaetes including the capitellid polychaetes which they most intently take after. Oligochaetes are basic in benthic examples, and are regularly predominant in naturally enhanced silt if a strainer of 0.3 mm or less is utilized.

• Recognizable proof of oligochaetes requires dismemberment, and, regularly, utilization of histology and sequential areas to derive life systems. This isn't to be attempted daintily, and there are no ongoing ID devices for the Australian fauna. Brinkhurst (1982), however it tends to the British fauna, remembers notes for study techniques and just and succinctly depicts families and genera, a considerable lot of which are probably going to happen in Australian waters.

Answer 2

Similarity between the arrangement of chaetae in an oligochaetes and polychates :

• Polychaetes are anneals worms that are usually present in "marine environments". Earth worms are 'annelids' too, but they are the oligochaetes.
• The primary differences between "polychaetes and oligochaetes" that can be used to categorize them are the "parapodia and chaetae".
• Polychaetes are having them and oligochaetes are don't. Oligochaetes are two sided, segmented, vagile annelids sharing with polychaetes two types of chaetae (hairs and crotchets) and their location in four bundles, but inadequate the "parapodia and paired head appendages".
• The "size of freshwater oligochaetes" are varies usually between "1 mm" and "several centimeters".
