Eutherians, also known as placental mammals, primarily inhabit terrestrial environments, but some species have adapted to aquatic life. Notable examples include whales, dolphins, and manatees, which have evolved specialized features for living in water. However, the majority of eutherians, such as humans, dogs, and elephants, are land-dwelling creatures. Thus, while some eutherians thrive in aquatic ecosystems, the group as a whole is not exclusively aquatic.
Eutherians and monotremes are in the phylum Chordata.
Yes. About 94% of living mammals are eutherians.
Eutherians are a group of mammals consisting of placental mammals plus all extinct mammals that are more closely related to living placentals (such as humans) than to livingmarsupials (such as kangaroos).
Eutherians are referred to as placental mammals because they have a placenta, which is an organ that nourishes the developing fetus during pregnancy.
They are Monotremes, marsipuals, eutherians.
they live in water
Eutheria is a subclass of mammals that includes placental mammals, which give birth to live young that have been nourished in utero by a placenta. Eutherians are the most diverse and successful group of mammals on Earth, and they include humans, elephants, dogs, and whales.
Manatees do live in salt water if they live in Florida they live in salt water and they live in springs if it is warm
They live in water, some species live in salt water, others live in fresh water.
They don't choose to live in water, they have to live in water. Certain species can live for an extended amount of time out of water, but they have to return to water to survive.
Water Louse obviously live in the water.
No seahorse can live in tap water they can only live in salt water
