The question is asking about the comparison between classes of phylum anelida as well as the phylum platyhelmithes on the basis of similarities and differences between their classes.
00:26
So the phylum anelida has been classified into three major classes.
00:34
The first class is oligoceta, second class is polykita, and the third class is herodinia.
00:47
Some of the similarities between the members of these classes includes they have organ level of body organization.
01:00
They are triple plastic animals that is characterized by the presence of three germ layers.
01:07
They are silomate organisms that is having the presence of true body silo.
01:14
Also they have the segmented body.
01:21
Now let us see some differences between the three classes of philem anelida.
01:29
The members of class oligocita are primarily fresh water or there may be some terrestrial whereas the members of class polyquita are marine fresh water as well as terrestrial.
01:49
Also the members of class herodinia are marine fresh water and terrestrial.
02:01
Class oligoteta having the presence of few ctis on their body.
02:07
Polyketa have many ct as the name polysuget suggest and class herodinia having no ct.
02:15
These are the appendages that help in the movement of members belonging to these classes.
02:20
Members of class oligo -kita having no parapodia.
02:26
Polykita have the presence of parapodia and class herodinia do not contain parapodia.
02:38
Next, the members of class oligo -kita are characterized by the presence of phlytellum in them.
02:44
Whereas the members of polykita as well as the herodinia do not have the presence of clytem in them.
02:56
The other feature is the members of oligocita as well as the polykita having no succor in their body, whereas the members of class herodinia have the presence of suckers in their body.
03:13
Examples of these three classes include earthworm belongs to the class oligo kita, neres belongs to the class polykita, and leaches belongs to the class herodemia.
03:27
The next point is members of oligocita are hermaphrodite, that is the male and female sex are present in the same individual, whereas the members of oligocita are diaceous, that is, they have the separate sexes, and also the members of class herodemia are hermaphrodite.
03:51
The next phylum is phylam platyhelmintis.
03:54
And the three major classes of this phylum includes the first class is turbillaria, second is trimatoda, and the third class is sistoda.
04:13
Some of the similarities between the members of these three classes includes they are characterized by organ level of body organization...
