There is simple trick to remember this fact if it's a Coelomate or not:

Prince Played Needless Music

This trick will help you remember which are the items that are NOT Coelomate. Hence all other can be remembered as Coelomate . 

  • Porifera - Prince
  • Platyhelminthes - Played
  • Nematoda - Needless  
  • Mollusca - Music

Now let's see the list once more (only remember the bolded one's that are not Coelomate, others are all coelomates )

  • Porifera - Not needed
  • Cnidaria - Coelomate
  • Platyhelminthes - Pseudocoelomate 
  • Nematoda - Pseudocoelomate 
  • Annelida - Coelomate
  • Arthropoda  - Coelomate
  • Mollusca - Less Coelomate
  • Echinodermata  - Coelomate
  • Protochordata - Coelomate
  • Vertebrata - Coelomate
