An example of an aquatic lifeform
Aquatic lifeforms, in the Encyclopaedia Cosmosica's definition, are animals or plants that live or grow in or near a liquid environment, especially water. Examples on the planet Earth comprise vertebrates, such as fish, and invertebrates, such as molluscs, as well as air-breathing finned mammals such as cetaceans (e.g. dolphins) that cannot survive on land, and footed mammals (e.g. otters) that live mainly in water. Intelligent aquatic lifeforms often invent survival gear that allows them to live outside their moist habitats, e.g. the Tourans' "dry suits". Aquatic lifeforms that the Inspector has encountered on his adventures include the Asterozoids and the Ocean Demons.
