Seahorses are fish; therefore, like all vertebrates, they have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
Most Echinoderms have radial symmetry. Sea Urchins, Starfish, Sand Dollars, etc.
Sea urchins!
A sea urchin has radial symmetry, meaning it is symmetrical around a central axis, like a wheel. This symmetry allows them to have multiple planes of symmetry passing through the central axis, giving them equal parts around the center.
nope. Some bivalves have bilateral symmetry but no radial symmetry.
Sea urchins belong to the kingdom Animalia, which is one of the five kingdoms of living organisms. Within the kingdom Animalia, sea urchins are classified under the phylum Echinodermata. Echinoderms are characterized by their spiny skin and radial symmetry, which sea urchins exhibit prominently.
Some examples of creatures with radial symmetry include jellyfish, sea stars, and sea urchins. These animals have body parts arranged symmetrically around a central axis, allowing them to move and feed in all directions.
Radial, meaning that however you cut them in half the two parts will always be the same - round symmetry, if you will, also found in sea urchins and the like. This is not the most common form of symmetry; bilateral symmetry is (left and right are the same).
No. Not even close. Sea urchins are small, herbiverous marine invertebrates with spines.
Their early larvae have bilateral symmetry, but as they get bigger they develop fivefold symmetry. This is apparent in the regular sea urchins, that have roughly spherical bodies, with five equally sized parts radiating out from their central axes.
No, They are bilaterally symmetrical. Radially symmetrical animals include echinoderms (starfish, sea stars, sea urchins) and many plants.
Deuterostomes that show radial symmetry in their adult form called phylum Echinodermata. Phylum Echinodermata are things like sea stars, sea urchins and sea cucumbers.
Yes they are. They are flattened burrowing sea urchins.
