Study Notes
Tentacles
- Long, flexible structures surrounding the sea anemone that help capture prey.
- Equipped with specialized cells called nematocysts used for stinging.
Oral Disc
- The upper surface of the sea anemone where the mouth is located.
- Typically surrounded by tentacles and serves as the feeding area.
Mouth
- The opening through which food enters the body.
- Located in the center of the oral disc.
Pharynx
- A muscular tube connecting the mouth to the gastrovascular cavity.
- Aids in the digestion and transport of food.
Complete Septum
- A wall-like structure that divides the gastrovascular cavity into compartments.
- Enhances the efficiency of digestion and nutrient absorption.
Incomplete Septa
- Partially developed partitions within the gastrovascular cavity.
- May provide some structural support but are less effective than complete septa.
Pedal Disc
- The base of the sea anemone that anchors it to a substrate.
- Used for attachment to rocks, coral, or sandy surfaces in marine environments.
Acontia
- Thin, thread-like structures found within the gastrovascular cavity.
- Contain nematocysts and help defend the anemone or capture prey.
