5 characteristics of phylum ARTHROPODA
Answers
Insects such as ants, dragonflies, and bees
Arachnids such as spiders and scorpions
Myriapods (a term which means “many feet”) such as centipedes and milipedes
Crustaceans such as crabs, lobsters, and shrimp
It may help to remember that the term “arthropod” comes from the Greek words for “jointed foot.” If the organism has an exoskeleton with joints between its feet and its body, it is probably an arthropod!
Arthropods are a lineage of life that developed skeletons on the outside – their hard shells, made of a material called “chitin” – instead of on the inside for structural support.
Arthropods’ bodies also have other important differences from those of vertebrates like ourselves – their organ systems are simpler and less efficient, which limits the size arthropods can attain.
Answer:
Arthropoda actually means and can be split into two parts
Arthon- Jointed ; podos- legs
#Arthropoda, animals having jointed appendages or legs.
#It is a phylum of triploblastic, haemocoelomic, segmented invertebrates having head, thorax and abdomen, a chitinous exoskeleton and jointed legs and appendages.
#Most successful phylum on the Earth that has ever existed.
#Habitat: They are mostly aquatic, few are terrestrial and very few are parasitic.
#Cephalothorex: Head is often fused with thoracic segments to form cephalothorax.
#Thorax and abdomen have a pair of biramous appendages in each segment.
#Respiration: through the gills or general body surface.
#Excretory organs are modified coelomoducts which may either maxillary glands or antennary glands.
##Examples: Cancer (crab), Palaemon (Prawn), Daphnia (water flea) etc.
###Arthropods were first studied by Aristotle.
###Von Siebold coined the term Arthropoda.
