If you mean the second most diverse animal phylum in terms of number of species, it would probably be the nematodes, which are a type of worm, or chordates, which includes humans. Arthropods are the most species rich animal phylum.
The phylum with the second most diverse range of species is Arthropoda, which includes insects, arachnids, crustaceans, and other groups. Arthropods have a wide variety of adaptations and occupy diverse habitats, making them one of the most successful and numerous groups of animals on Earth.
Mollusca
molluscs
Ticks belong to the phylum Arthropoda, which is a diverse group of invertebrates that includes insects, spiders, and crustaceans.
Phylum is the second broadest classification grouping for animals, following Kingdom. Phylum divides animals into major groups based on general characteristics such as body structure and organization. Examples of phyla include Chordata (which includes vertebrates) and Arthropoda (which includes insects and crustaceans).
Ragworms are in the phylum Annelida, which is a diverse group of segmented worms that includes earthworms, leeches, and polychaetes like ragworms.
Flagellates are a diverse group of single-celled organisms belonging to various phyla, including the phylum Euglenozoa and phylum Dinoflagellata. These organisms possess whip-like structures called flagella that they use for movement. Flagellates can be found in diverse environments such as freshwater, marine, and soil.
The lungworm belongs to the phylum Nematoda. Nematodes are a diverse group of roundworms that can be found in various habitats, including the lungs of animals.

Phylum arthropoda is the most diverse in species, with the highest count known of described species in any animal phylum. Over a million species under the phylum have been described and biologists estimate that millions of species have yet to be described, particularly amongst the insects.

Former Answer by some dummy: "The most diverse group is insects, which belong to the group ARTHROPODA*.*Arthropoda-Largest and most diverse animal phylum, mostly insects."This answer is completely wrong based on the question.Arthropods are invertebrates! They are the most numerous INvertebrates.The most diverse vertebrates are BONY FISH.
A diverse phylum comprising the multi segmented worm like animals.
Arthropods are unique for their jointed appendages and exoskeleton made of chitin. This phylum includes animals such as insects, arachnids, crustaceans, and myriapods, making it the largest and most diverse phylum in the animal kingdom.
The fungal phylum with the largest number of species is Ascomycota. This phylum includes a diverse range of fungi, such as yeasts, molds, and truffles, with an estimated 64,000 to 66,000 species.
The most successful phylum in the animal kingdom is Arthropoda. It includes insects, arachnids, crustaceans, and other groups, with millions of species described so far. Arthropods also have a high total mass due to their abundance and diverse ecological roles.
