Answer:
Echinodermata – bilateral symmetry as a larva, water vascular system
Explanation:
Echinodermata are marine animals that include groups such as sea stars, sea urchins, sand dollars, sea cucumbers, and sea lilies. As adults they have radial symmetry, usually five point radial symmetry. One of their unique characteristic is water vascular system which consists of a network of fluid-filled canals involved in gas exchange, feeding, sensory reception and locomotion. Their digestive and nervous systems are very simple.
The study of animals is called zoology.
The correct answer to the question is option B which is Echinodermata – bilateral symmetry as a larva, water vascular system.
When a species has two equal halves when it cut through the specific plane is called bilateral symmetry.
According to the question, the Echinodermata has bilateral symmetry and consists of a water vascular system that helps to move in any direction.
An example of the Echinodermata is starfish.
Hence, the correct answer to the question is option B.
