Sea Wasp

No good photo of this species is available yet, so this Illustration was created with ChatGPT Image 2.5. It is an attempt to get the anatomy and features right, and may contain small errors.

The Sea Wasp has a smooth, clear, elongated rectangular bell. Four long, thin tentacles trail behind it, one from each corner. Its tentacles may have a pink tint.

The Sea Wasp uses stinging cells in its tentacles to immobilize small prey, such as larval fish, before moving them into its bell for digestion. It is most often seen at night in sheltered areas and may be attracted to light. About eight days after a full moon, large numbers may gather near the surface close to shore to spawn. Night diving is therefore not advised 8–10 days after a full moon. Its sting can cause intense pain.

According to DAN, after a sting, leave the water, apply vinegar for at least 30 seconds, carefully remove any remaining tentacles, and apply hot water that will not burn the skin. Seek medical help for severe pain, breathing problems, or other serious symptoms.
