Subclass: Palpata
Order: Haplotaxida
Family: Acanthodrilidae 
Genus: Lumbricus
Species: L.terrestris
Latin meaning “little ring”, sometimes also called as segmented worms.
The animals that are classified as Annelids are segmented worms.
No legs
No skeleton
Have body that are divided into little segments
There are about 22,000 species including rag worms, earthworms, and leeches.
TO THE ECOSYSTEM:
Without worms, plant would not be able to grow, as it helps fertilize, mix, and provide proper minerals to soil

3. ANATOMY (EARTHWORM) BODY Metamerism
Are segmented which looks like many little rings joined together
Make them flexible and strong in its movement
Made out of segmented bodies
Structural function
Help them to move
MUSCLE
Setae
Control the worm when moving through soil
They can relax or contract their muscles independently
Lengthen one specific area

Fish
Small shrimp
Other worms

8. Hirudinea (LEECHES) Kingdom: Animalia Hirudinea means leeches
Mostly freshwater, some marine and terrestrial
Consume blood
No parapodia or setae
Clitellum present
Kingdom: Animalia
Phylum: Annelida
Class: Hirudinea
Order: Arhynchobdellida
Family: Hirudidae
Genus: Hirudo
Specis: Hirudo medicinalis

9. ANATOMY (MEDICINAL LEECH)
BODY
Cylindrical bodies
Divided into three segments
The top part
Black or brown color
They don’t really have muscle
Therefore they could only swim or attach themselves into something using their sucker
SUCKER
Posterior
To attach themselves
Anterior
To eat
Kingdom: Animalia
Phylum: Annelida
Class: Hirudinea
Order: Arhynchobdellida
Family: Hirudidae
Genus: Hirudo
Specis: Hirudo medicinalis

10. REPRODUCTION
Polychaeta and Oligochaeta can both reproduce sexually and asexually, while leeches can only reproduce asexually.
Asexual reproduction does not involve the formation of gametes (sperm and eggs), it is by budding
