The arthropods are mainly classified depending upon the appendages present.
The phylum arthropoda is classified in to four subphylums
subphylum: Trilobita (Tri= three; lobita=lobe). The dorsal exoskeleton shows three lobes
subphylum: Chelicerata (Gr., chele= claw + keros=horn+ata=group)
subphylum : Myriapoda
subphylum: Hexapoda
subphylum: crustacea
no, i dont know what they are, but they are not arthropods
size and shape
NO. Arthropods do not have a 4 chambered hearts.
Do arthropods have backbones?No, it is the exoskeleton that holds the arthropod's body together. arthropods are invertebrates, which means they do not have backbones.
Tracheal tubes
No, worms are not arthropods because they do not have a shell. All arthropods have an external shell or an exoskeleton which is used to define them or classify them.
Trilobites are arthropods (like spiders)
How do they defend them selves??
Some arthropods can produce a smelly odor like a carabid beetle or some millipedes. Some will bleed a toxic blood to destroy their enemies.
Geologists classify crystal structures based on the arrangement of atoms within the crystal lattice, the symmetry of the crystal, and the types of bonds between atoms. Common crystal structures include cubic, tetragonal, orthorhombic, monoclinic, and triclinic structures.
The scale used to classify and describe the effects of earthquakes on structures and local damage conditions is the Modified Mercalli Intensity (MMI) scale. This scale ranges from I (not felt) to XII (total destruction) and assesses the level of shaking and resulting damage experienced at a specific location during an earthquake.
no arthropods have endoskeletons, completely different structures nothing like exoskeletons, exoskeletons are outer skeletons made of chitin only found on arthropods, endoskeletons are inner support structures like your skeleton, made of bone and/or cartilage.
Aquatic arthropods typically exchange gases through gills. Gills are structures that are rich in blood vessels and provide a large surface area for gas exchange to occur, allowing the arthropods to extract oxygen from the water and release carbon dioxide.
The genetic information, morphological structures and the fossil records are some of the required information required in order to classify the animals.
Malpighian tubules are the structures that help arthropods maintain water balance. These tubules are responsible for removing waste and regulating the concentration of solutes in the hemolymph, helping to conserve water in arthropods' bodies.
Most aquatic arthropods reproduce by laying eggs. These eggs can be deposited on structures in the water or carried by the female until they hatch. Some aquatic arthropods also undergo complex mating rituals or behaviors before reproducing.
