Question

Quizplus · Accepted Answer

The umbrella-shaped and translucent body, the pulsing movement, and the presence of long trailing tentacles all suggest that this creature is a jellyfish or another type of cnidarian. The burning sensation felt when touched indicates that it may have stung the person, which is a common trait of cnidarians. Porifera (sponges) do not have tentacles or a body shape resembling an umbrella, while Platyhelminthes (flatworms) and Mollusca (mollusks) have very different body plans and modes of movement.
