Study Notes
Distinguishing Characteristics of Insects
- Insects are distinguished from non-insect hexapods by having a three-part body (head, thorax, and abdomen) and a hard exoskeleton made of chitin.
Unique Feature of Insect Body Structure
- A unique feature of insect body structure is the three-part body (head, thorax, and abdomen) with a hard exoskeleton made of chitin.
Non-Insect Hexapods
- Non-insect hexapods belong to the group of arthropods called Entognatha, which includes proturans, collembolans, and diplurans.
Distinguishing Insects from Other Arthropods
- Insects are separated from other arthropods by having a three-part body (head, thorax, and abdomen) and a hard exoskeleton made of chitin.
Ecological Niche Occupation
- Insects are unable to occupy an ecological niche that requires a large body size, as they have a hard exoskeleton that restricts their growth.
