Earthworm Phylum Characteristics
- Metamerism. All annelid bodies are divided serially into segments called metameres.
- Body Wall. The body wall has an outer circular muscle layer and inner longitudinal muscle layer.
- Chitinous setae.
- Coelom.
- Closed Circulatory System.
- Complete Digestive System.
- Respiration.
- Excretory System.
How is the earthworm adapted to its feeding habits?
Earthworms are adapted for digging and feeding in the dirt. They squeeze their circular muscles to dig. As they eat they process food through their one-way gut and poop into the soil.
How are earthworms adapted to the air?
The worm’s skin is protected by a thin cuticle and kept moist by a slimy mucus. This lets it absorb the oxygen it needs and expel carbon dioxide. If a worm is dried up by the sun, it will die because the exchange of gases can’t take place.
What are two ways in which an earthworm’s body is adapted to soil?
1: it has slimmy skin which helps it to move in the soil. 2: it has pores on skin through which it can breathe even inside the soil.
Can worms live when cut in half?
If an earthworm is split in two, it will not become two new worms. The head of the worm may survive and regenerate its tail if the animal is cut behind the clitellum. But the original tail of the worm will not be able to grow a new head (or the rest of its vital organs), and will instead die.
How is earthworm body shape adapted for its environment?
An earthworm has a streamlined body with no antennae or fins or arms or legs! This streamlined shape is an adaptation to living in narrow burrows underground and the need to move easily through the soil. An earthworm has circular muscles that surround each body segment.
Can worms feel pain?
But a team of Swedish researchers has uncovered evidence that worms do indeed feel pain, and that worms have developed a chemical system similar to that of human beings to protect themselves from it. The Swedish scientists, J.
Can a worm survive in water?
