Radial symmetries
When feeling in danger, octopuses spread out their arms, pump water through their siphon and exhibit phosphorescent pigments. Octopuses are animals with bilateral symmetry, despite these postures make them looking like radial. “My” octopus did not ink, maybe it was not so frightened after all.
Sedentary marine tube worms quickly retract their colorful bristles (visible) in their calcareous tube (not visible). Despite their exposed, radial head, they are bilateral annelids
Sea anemones are true radial animals. This anemone belongs to the Actinaria subclass
Sea urchins (Echnoidea) are true radial symmetry animals

No sand can be collected, no shell can be picked… and of course no sea creature can be fished. That is why the waters comprised in the Natural Marine Area of Capo Carbonara swarm with fishes.
