What are 3 characteristics of arthropods that help them survive?
Arthropods are animals with jointed appendages and a chitinous exoskeleton. They are adapted to live in terrestrial environments. Some of these adaptations include reduced body size, presence of antenna and compound eyes, complete digestive system, and breathing through trachea, gills or book lungs.
Which of the following is a trait of Arthropoda?
The distinguishing feature of arthropods is the presence of a jointed skeletal covering composed of chitin (a complex sugar) bound to protein. This nonliving exoskeleton is secreted by the underlying epidermis (which corresponds to the skin of other animals).
Which of the following is the characteristic feature of Arthropoda?

What trait separates birds from amphibians?
The amniotes—reptiles, birds, and mammals—are distinguished from amphibians by their terrestrially adapted (shelled) egg and an embryo protected by amniotic membranes.
Do slugs cells?
It is on this basis that one often finds in the literature that migrating slugs have about 100,000 cells. Using a similar method of estimating cell size, Bonner and Frascella (1953) isolated the amoebae from migrating slugs in standard salt solution (Bonner, 1947) and measured their diameters as spheres.
Do arthropods have 3 embryonic germ layers?
Arthropods are triploblastic (they have three germ layers) and are coelomate organisms.
What are characteristics of arthropods?
All arthropods share these characteristics:
- Exoskeleton. An exoskeleton is the supporting structure on the outside of the body of an arthropod.
- Segmented bodies.
- Jointed appendages such as mouthparts and antennae.
- Bilateral symmetry.
- Dorsal blood vessel.
- Ventral nerve cord.
