Study Notes
Crayfish Anatomy and Functions
- Cheliped: Large claws essential for defense and capturing prey, playing a vital role in the crayfish's survival.
- Antenna: Larger sensory organs that detect environmental changes and help the crayfish navigate its surroundings.
- Green Gland: Part of the excretory system responsible for filtering waste from the blood, crucial for maintaining internal balance.
- Stomach: The primary organ for digestion, where food breakdown occurs to extract nutrients.
- Gills: Respiratory organs allowing crayfish to extract oxygen from water, enabling aquatic life.
- Walking Legs: Limb structures that facilitate locomotion, allowing crayfish to move efficiently in water and on substrate.
- Uropod: Located on each side of the telson, aids in maneuvering through water, enhancing swimming abilities.
- Intestine: Organ that absorbs nutrients from digested food and eliminates waste, vital for nutrient uptake.
- Telson: The terminal part of the crayfish that provides propulsion, enabling quick movement in water.
- Heart: Central component of the open circulatory system in crayfish, responsible for circulating blood.
- Digestive Gland: Produces digestive enzymes and absorbs nutrients, supporting the crayfish's metabolic needs.
- Compound Eyes: Comprised of multiple light detectors, providing a wide field of vision and sensitivity to movement.
- Cephalothorax: Composite body part formed by the head and thorax, housing vital organs and appendages.
- Abdomen: The posterior section of the body, contributing to the overall structure and function of the crayfish.
- Swimmerets: Appendages that create water currents over the gills for respiration, function in reproduction, and assist in swimming.
