Question

Which one correctly describes the location of body parts in Pheretima?

• A. Two pairs of accessory glands in 16-28 segments
• B. Two pairs of testes in 10th and 11th segments
• C. Four pairs of spermatheca in 4-7 segments
• D. One pair of ovaries is attached over septum 14-15 segments
  

Answer 1

The correct option is B Two pairs of testes in 10th and 11th segments

In Pheretima or earthworms, a pair of accessory glands are present in the 17th and 19th segments. Two pairs of testes are present in the 10th and 11th segments. A pair of spermathecae are located in each segment from 6th-9th segments. They are structures that receive sperms after mating. One pair of ovaries is attached at the inter-segmental septum of the 12th and 13th segments.
