Some animals, including snails and clams, have managed to become photosynthetic themselves, capturing the energy from the sun and converting it into biological energy via photosynthesis. All food ultimately comes from photosynthesis, either directly from plants or indirectly through animals that consume plants.
Some animals have managed to become photosynthetic by turning carbon dioxide and sunlight into sugar and oxygen, just like plants. Corals are the most famous example, able to photosynthesize thanks to a special partnership with a single-celled algae called zooxanthellae.
Mollusks are the most diverse group of animals when it comes to body forms, ranging in size from tiny grains of rice to colossal squids. Second only to the arthropods, mollusks have a wide variety of species encompassing snails, clams, octopuses, and more.
The world of mollusks is incredibly diverse, with giant clams, snails, slugs, and cone snails all belonging to this phylum. Each type of mollusk has its own unique characteristics, making them interesting to researchers and animal enthusiasts alike.
