Study Notes
Arthropods Overview
- Arthropods belong to the phylum Arthropoda.
- Main body structure characteristic includes a segmented body, jointed appendages, and an exoskeleton made of chitin.
Exoskeleton Structure
- The epicuticle in arthropods' exoskeleton serves as a waterproof layer, protecting the organism from desiccation and providing structural integrity.
Crustaceans Classification
- Crustaceans fall under the class Malacostraca within the phylum Arthropoda.
- Crustaceans possess two pairs of antennae.
Body Segment Organization
- Arthropods’ body segments are grouped into specialized regions called tagmata.
Digestive System Function
- The digestive system in arthropods includes a specialized area for the storage of food known as the crop.
Exoskeleton Functions
- The jointed exoskeleton provides structural support, protection from predators, and facilitates movement.
Decapod Classification
- The order Decapoda includes animals such as shrimp, crabs, and lobsters.
Claw Function in Decapods
- The larger claw in decapods primarily functions for defense and capturing prey.
