because since invertabrates have no bones the can sqeeze so like the octupus they are small so that they can sqeeze through cracks.
all invertebrates are smaller than vertebrates. :)

they dont have a backbone
Not all invertebrates are smaller than vertebrates. Molluscs such as the Giant Squid can weight up to 275 kg. However, in general, and particularly in terrestrial habitats, it's because the stiff structure supplied by the vertebral column allows the organism to better support its weight against the force of gravity.
no way lizards eat mostly insects smaller than them. like flies and ants.
Vertebrates have an internal skeleton and invertebrates have external skeletons. Vertebrates are able to grow larger than invertebrates because of this. Invertebrates would crush themselves under their own skeletons if they grew to a large size.
mostly babies that are smaller because they are premature.
Both Venus and Mercury fit this description. Mercury is the smaller of the two.
Grey wolves feed on mostly and animal that is smaller than it or one than is already dead.
Most reptiles are predators which means they eat other animals to survive. But many reptiles are not very large so they limit their prey to animals that are smaller than they are such as invertebrates, amphibians, small mammals and small reptiles. There are a few reptiles though that are herbivores and feed mostly on plant material.
some smaller planets are more dense then the larger ones that are made up of mostly gases.
Definetely the sea, Even if you took all the Insects (largest group of land dwelling invertebrates by far) and the plants, It would pale in comparison to the amount of flora and invertebrate fauna in the oceans. The Ocean is where Life began and it has more species diversity, quantity, and mass than double the invertebrates on the Earth's land.
