These are not Cribrinopsis albopunctata.

The following are identifying characteristics of Urticina mcpeaki

  1. The verrucae (wart like tubercles or spots) on the side are sticky and almost always have debris sticking to them
  2. The top row of marginal structures (spots) has visible openings
  3. The tentacles have longitudinal stripes or chevrons.

There is usually not any debris sticking to the sides of Cribrinopsis albopunctata, nor do they have openings in the top row of spots.

Thank you for liking the pictures. I am very happy with the Olympus 50mm lens.
