What is common between earthworm and Periplaneta?

  • A
    Both have red coloured blood
  • B
    Both possess anal styles
  • C
    Both have malpighian tubules
  • Correct answer
    D
    Both have segmented body

Solution

Segmentation occurs in three highly organized phyla-annelida (earthworm), arthropoda (Periplaneta) and chordates. The body is often divided both externally and internally into a number of segments (metameres) e.g., annelids. Segmentation is mostly external in arthropods and mainly internal in man and other chordates.

Hence, the correct answer is option: 'D'.
