Sea anemones may look alien, but scientists just found out they're hiding an ancient body 'blueprint' – one that most animals, including humans, still follow.

Starfish are echinoderms, a form of invertebrate marine animals known for radial symmetry and having spiny skin. Researchers said most animal species have similar genetic structures, prompting ...

Many marine animals, including the jellyfish, can regenerate limbs. Scientists recently did a study to find out how moon jellyfish recuperate after suffering an injury.

Radial symmetry is key to how moon jellies propel themselves and eat. (The two functions are related: The same flapping motion that moves a jellyfish through the water also sends food-rich water ...

While people and many animals might look pretty symmetrical on the outside, inside our bodies we are all fundamentally asymmetric. Snails are similarly asymmetric in their appearance. Now ...

Bilateral symmetry is one such feature found in flowers of various taxa, such as orchids and legumes. Animals enter these bilaterally symmetrical flowers from the front with their ventral side down.
