insects
All phyla contain invertebrates. The only one that contains vertebrates is the phylum Chordata, but it also contains some invertebrates.
Correct,Insects ARE the only Invertebrates to evolve to fly!
Ganglia are called simple brains in invertebrates .
All animals are invertebrates, except for fish, amphibians, reptiles, birds and mammals. These are known as vertebrates (animals with a backbone; vertebra = backbone) and account for only 2% of the animal kingdom, at most (as we probably haven't discovered all invertebrate species yet)!
sponges
no it isn't all sea animals are vertebrates only turtles are invertebrates but they have a backbone too.
Insects are the only flying invertebrates.
invertebrates
The best-known example is probably the Monarch butterfly.
The smallest group of invertebrates is the phylum Placozoa, which consists of a single known species, Trichoplax adhaerens. These simple, flattened organisms are composed of only a few cell layers and lack organs or distinct tissues.
I think the word you're after is just invertebrates. Vertebrates and those animals with a notachord are known as the Chordata - but those with neither spinal chord nor notachord are simply invertebrates.
Lobsters are invertebrates, as in they have no back bone.
