Similarities on the bodies of spiders and butterflies

The two have something in common almost exclusively in the big picture (at the arthropod level):

1。body segmentation (heterorhythmic segmentation);

2。Most somites have paired appendages;

3。with chitin exoskeleton with peeling phenomenon;

4。The muscles are striated muscles with strong contractility;

5。has a mixed body cavity, that is, a blood cavity;

6。The blood circulation is open-tube circulation;

7。The excretory organ is the Malcolski duct;

8。cordoid nerves, the first few ganglia heal into the "brain", with a single eye;

9。Dioecious, hermaphroditic, and the mode of reproduction is oviparous.

2. Butterflies have 6 legs, while spiders have 8 legs.

3. Butterflies are knowledge animals, while spiders are carnivores.

4. Butterflies are non-venomous, while spiders are venomous.

Exoskeleton, head, thorax, abdominal structure, same carnivore, etc.

1. Both spiders and insects have an exoskeleton structure that protects the body, provides support, and is constantly renewing during the growth process.

2. Spiders and insects are composed of three parts: head, thorax and abdomen, of which the abdomen is the main part of Yu Jian where the organs of digestion, discharge and reproduction are located.

3. Spiders and insects are both carnivores, feeding on small insects or other invertebrates and even small vertebrates (such as frogs).

Similarities:

1。body segmentation (heterorhythmic segmentation);

2。Most somites have paired appendages;

3。with chitin exoskeleton with peeling phenomenon;

4。The muscles are striated muscles with strong contractility;

5。has a mixed body cavity, that is, a blood cavity;

6。The blood circulation is open-tube circulation;

7。The excretory organ is the Malcolski duct;

8。cordoid nerves, the first few ganglia heal as "brain";

9。Dioecious, hermaphroditic, and the mode of reproduction is oviparous.

10。All belong to arthropods.

Differences:1. Butterflies are insects (Insecta) while spiders are not (Arachniformes)2. Butterflies have 6 legs, while spiders have 8 legs.

3。Butterflies are vegetarian animals, whereas spiders are carnivores.

4。Butterflies are non-venomous, whereas spiders are venomous.

5。Butterflies have wings while spiders have no wings.

6。Butterflies can fly, but spiders can't.

7。The butterfly body is divided into three segments: head, thorax, and abdomen, and the spider is divided into two segments: cephalothorax and abdomen8. Butterflies have compound eyes, and spiders have one eye.

9。Butterflies don't take care of their young, spiders do.

10。Butterflies have a pupal stage, spiders do not.

11。Butterflies have antennae, spiders don't.

Don't forget to list me as an oh.

The spider and the butterfly are in interracial love, lay eggs on their deathbed, and give birth to strange babies!

Same: It belongs to the same phylum Arthropods, and both have exoskeletons and appendages.

Different: Butterfly belongs to the phylum Arthropod, Insecta, the body is divided into three segments: head, thorax and abdomen, with antennae and three pairs of legs; Spiders belong to the phylum Arthropoda, arachnids, the body is divided into two segments, the head and thorax, and the abdomen, without antennae, four pairs of legs.

Butterflies are insects, while spiders are animals.

Butterflies have wings and antennae, while spiders do not.

Butterflies have two eyes and spiders have eight eyes.

Butterflies have six legs and spiders have eight legs.
