According to Tippo's classification of the kingdom Plantae, the phylum Tracheophyta (vascular plants) is divided into three subphyla: Lycophyta (club mosses), Pterophyta (ferns and their relatives), and Spermatophyta (seed plants). Each subphylum represents a distinct group of vascular plants with unique characteristics and reproductive strategies.
There are differences within the different phyla (sub-order) of invertebra but they all differ from vertebrae in the lack of cerebialization, they lack one brain. Some phyla like mollusks have pair masses of neurons termed ganglia that handle different functions, like eating or movement.
AIDS has affected the economy of Sub-Saharan Africa by reducing the available work force. Many people with AIDS either pass away or are too ill to work.

Snails belong to the phylum Mollusca, which also includes other animals such as clams, octopuses, and squid. This phylum is characterized by soft bodies, often covered by a hard shell, and a muscular foot used for locomotion.
These are the eleven common Phyla but there are over 30 different classification of Invertebrates!Invertebrata Phyla includes;* Arthropoda * Nematoda * Mollusca * Annelida * Nemertea * Platyhelminthes * Rotifera * Acoelomorpha * Ctenophora * Cnidaria * Porifera Also included, but not limited, are a sub-phyla of Marine Invertebrates. Hope this helped.
Insects, Arachnids (scorpions and spiders), Crustaceans (crabs, lobsters, shrimp), Millipedes and Centipedes are all classified as Arthropods. An article that goes into more detail of the sub-phyla and classes can be found at the related link below.
