Study Notes
Box Jellyfish Overview
- The bell of box jellyfish is uniquely shaped like a box, contributing to their common name.
- Box jellyfish are classified under the class Cubozoa.
Morphological Similarity
- Cubozoans share similar morphology with scyphozoans, another class of jellyfish.
Tentacle Arrangement
- The arrangement of tentacles distinguishes cubozoans from scyphozoans, providing them with unique hunting capabilities.
Tentacle Structure
- Tentacles are attached to muscular pads called pedalia located at the corners of the square canopy, allowing for effective locomotion and feeding.
Digestive System
- In certain instances, the digestive system may extend into the pedalia, affecting how cubozoans digest their prey.
Nematocyst Configuration
- Nematocysts are arranged in a spiral configuration along the tentacles, enhancing their ability to subdue and capture prey effectively.
Eye Structure
- Cubozoans possess complex eyes made up of cornea, lens, and retina, showcasing advanced visual systems.
True Organs
- The eye components—cornea, lens, and retina—are considered true organs due to their formation from multiple interactive tissues.
Rhopalia and Vision
- Cubozoans have three sets of eyes within their Rhopalia, providing them active and effective vision crucial for hunting.
