Types of life in water include fish, plants, marine mammals, invertebrates, and amphibians.
The sudden appearance of most of the major animal phyla within the fossils early in the Cambrian period. This caused a sudden diversification of life.
Invertebrates are more common an vertebrates. An estimated 98% of the world's animal life is made up of invertebrates.
The Cambrian era saw the rapid evolution and diversification of many animal phyla, known as the Cambrian Explosion. This era, approximately 541 to 485 million years ago, was a pivotal time in the evolution of life on Earth, leading to the emergence of a wide variety of body plans and organisms.
The most noteworthy feature of Paleozoic life is the sudden appearance of nearly all of the invertebrates animal phyla in great abundance at the beginning of the Cambrian. A few primitive fish like invertebrates, and then vertebrates , appeared in the Cambrian and Ordovician, scorpions in the Silurian period, land invertebrates and amphibians in the Devonian, land reptiles in the Carboniferous, and marine reptiles in the Permian. All reptiles increased in number and in variety by the late Permian. The plant life of the Paleozoic era reached its climax in the Carboniferous, and was then much diminished in the Permian.
If there is no invertebrates there will be no life on earth, for example pollinators such as bees and butterflies are important for plants to complete their life cycle.
