Answer 1

Hey man! Here's what you asked for, i didn't add photos since they're copyrighted and that's against our honor code.

Phylum	Class	Subclass	Common names	Characteristics	Representative genera
Mollusca	Polyplacophora	Paleoloricata	Chitons	They live worldwide from cold waters through to the tropics, but only in marine ambients. They bear a protective dorsal shell divided into 8 articulated plates. They have an antero-posterior differentiation but head/anus aren’t conspicuous. Tri-chambered heart.	NF
Loricata	Katharina
Gastropoda	Eogastropoda	Limpets	They’re characterized by a process called torsion where the visceral body rolls over the body and head during embryo development. They use an organ called radule to scratch the food. They live in all types of water and a lot of species live in ground. The majority of the species are protected by a shell (made of calcium carbonate with additions) that generally is right-turned. The head is well defined. They move with a muscular foot.	NF
Orthogastropoda	Snails and slugs	Helix (escargot snail)
Bivalvia	Anomalosdesmata	Clams, mussels, oysters and scallops	Head isn’t differentiated. No radule. The shell is divided into 2 plates (also called valves). All species are aquatic. They filtrate food from water. The muscular foot is used to excavate.	Anodonta (freshwater mussel)
Heterodonta
Palaeoheterodonta
Protobranchia
Pteriomorphia
Cephalopoda	Nautiloidea	Nautilus	The typical “muscular foot” is diversified into various appendixes (8 in octopi and 90 in nautilus). They have a radule but food is first met by their beak. Shell disappeared (except in nautiloidea). They have the ink gland used for escaping. They use siphon to propulsate.	Nautilus (chambered nautilus) Loligo (squid)
Ammonoidea	Ammonites
Coleoidea	Squids, octopus
Annelida	Polychaeta	Aciculata Sedentaria Basal polychaetes	Segmented worms	They’re aquatic animals, and the majority of them are marine. They’re characterized by bearing a pair of parapods (fleshy protrusions) along with numerous chaeatae (made of chitin) in their dorsal and ventral angles. Their body length ranges from planktonic scale to 3 cm.	Lugworm (Arenicola) Clam worm Alitta.
Clitellata	Oligochaeta	Segmented worms	There are aquatic and terrestrial species. They range in legth from 0.5 mm to 3 m. They’re well segmented worms with each segment having a pair of organs identical to the other segments. They don’t have appendixes except in the 1st segment (called prostomium) but have small chaeatae along the whole body. They move identical to a peristaltic wave. Near the mid segments of the animal there’s a structure formed by a defined number of modificated segments by the presence of numerous secretory glands forming the clitellum. They’re detritivorous. Are hermaphrodites.	Lumbricus (Earthworm)
	Hirudinea	Leeches	Parasitic or predatory worms (hematophagous). Are hermaphrodites. They’re internally segmented but in the exterior, it doesn’t look like it. They have suckers at both ends. Clitellum isn’t visible most of the time (only at reproductive station) The majority of species live in freshwater, but others are terrestrial, and others marine.	Hirudo (medicinal leech)
