i) How does the ability of phyla Annelida to move compare with the phyla Platyhelminthes, which prominently use adhesive/releaser glands to facilitate movement? Describe their movement using two examples from specific groups of annelids (structures & how it's used) in one or two paragraphs. ii) Describe the circulatory & nervous systems of phyla Annelida and how they relate to their metamerism. Finally, iii) compare your answer from part iii with the myriapods found in the phyla Arthropoda.

Expert Solution

Phylum Annelida

Aquatic annelid like Nereis- got lateral appendages and parapodia ( which help them in swimming by a sweeping movement)
Hirudinaria (blood sucking leech), Earthworm - possess longitudinal and circular muscles which help them in their locomotion.
closed circulatory system and presence of heart for pumbing blood.
their body surface is distinctly divided into segments/metamers.
Neural system consists of paired ganglia connected to double ventral nerve cord by lateral nerves.

Phylum Platyhelminthes

Eg: Taenia (tapeworm) , Fasciola
present adhesive/releaser glands to facilitate movement.
They contain longitudinal, circular and oblique layer of muscles.
some like fasciola move by beating of cilia.
open type of circulatory system.
segmentation is not present.
ladder like nervous system

( as the question for which answer is needed is not specified i will give answer for the 1st)

There are nine major phyla described - Mollusca, Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Arthropoda, Echinodermata, and Chordata, 1. which of these do you consider to be the most successful? 2.Explain your rationale for measuring success (e.g. total numbers, numbers of different species within the phylum, adaptability, specificity etc) and choose a representative animal within that phylum and discuss which aspects of its physiology and lifestyle have contributed to its success.
