# data[].attributes.body
1. A hard exoskeleton which .is made of calcium and do not have an internal skeleton
2. The head has two eyes, two pairs of antennae, and three pairs of mouthparts.
3. A pair of green glands excrete wastes near the base of antennae.
4. The abdominal segments have swimmerets.
5. The tail is fan-shaped , and ends in uropods and a telson.
6. The circulatory  system is open; there is no heart and the blood is pumped by vessels into sinuses, and does not flow in a close loop.
7. The nervous system consists of a primitive ventral nerve cord and ganglia system.
Brachyura

# data[].attributes.body
Myriapods have elongated bodies with numerous leg-bearing segments. It’s characteristics are: many pairs of legs, 2 body sections (head & trunk), one pair of antennae on the head, simple eyes, mandibles & maxiallae, respiratory exchange occurs through tracheal system.
Chilopoda

# data[].attributes.body
Exoskeleton
• 3 body regions: head, thorax, abdomen
• 3 pairs of segmented legs
• 1 pair of antennae
• most Insects have 2 pairs of wings (some insects for example ants, don’t usually
have wings; some insects, for example flies, only have 1 pair of wings)
Apis mellifera linnaeus

# data[].attributes.body
1. The body segmentation usually consists of: a head, a thorax and an abdomen.
2. Jointed appendages.
3. They have an exoskeleton which is firm but also flexible to move better.
4. An open circulatory system, the blood is not in vessels it flows freely
5. Especialized appendages have claws.
6. Eight appendages
7. No antennae, claws, or wings, but instead have mandibles: estructures for biting and chewing prey
Scorpiones

# data[].attributes.body
- They have jointed limbs which help them move easily. The jointed limbs are the parts were they can bend their legs.
- They are invertebrates, because of this fact they do not have a back bone as they don’t need it to stand upright and hold them in place.
- Instead of having a backbone they have an exoskeleton to keep all the organs in place and also for protection against the predators.
- They have good senses, they have a better eyesight as we do as they have more sofisticated eyes and can perceive other things that humans wouldn’t be able to do.
- There is a thing that we, humans and Arthropoda have in common, we have bilateral body symmetry which means that both sides are the same.
