Spiracles are present in Cockroach.

Here's the step by step explanation:

1. Earthworm: Earthworms do not have spiracles. They breathe through their skin. Oxygen and carbon dioxide pass in and out through the moist skin by the process of diffusion.

2. Starfish: Starfish do not have spiracles either. They have a water vascular system which helps in their respiration.

3. Cockroach: Cockroaches have spiracles. They are small openings on the sides of their bodies that allow them to breathe. Air enters and leaves the cockroach's body through these spiracles.

4. Sea anemone: Sea anemones do not have spiracles. They breathe by absorbing oxygen from water through their skin.
