It's a tricky question because insects have two kinds of eyes. There are simple eyes and compound eyes. Some insects just have one type, others have both types. The simple answer is, most insects have two eyes, but several of them have five eyes.
1. Only insects have wings 2. Insects have six legs 3. Only insects undergo complete metamorphosis 4. Insects have 3 distinct body sections 5. Insects have antennae 6. Insects have external mouthparts 7. Only insects have compound eyes 7 is the lucky number- if it meets at least 3 of these criteria, it is definitely an insect.
The spider is not an insect because it has eight legs, and insects have six legs. The spider is classified being in the group of Arachnids instead of being in the group of Insects, or Bugs.
One things that all insects have in common are legs with joints. They also all have an exoskeleton made, in part, of chitin. The insects also have bi-lateral symmetry.Most insects have eyes and legs. Some insects have wings, which allow them to fly around from place to place.
They have two eyes. These eyes are simple and NOT compound.
6 legs. (3 pairs of 2).
Yes they do have eyes.
Yes, two eyes.
Insects usually have 2 compound eyes but their vision has two distinct organs:compound eyes, which are made up of multiple lenses and cell groups (ommatidia) ranging in number from 2 to over 10,000 per eye in the dragonfly.simple eyes (ocelli) which have light detecting cells of various complexity, the simplest being "eye spots" or pigment pits. Many insects such as flies and wasps have 3 ocelli in a group between their compound eyes.(see the related link for more information on insect vision)
The eyes of a grasshopper are unique in the sense that they are not necessarily used for sight. They have compound eyes, which help them to determine shapes, color, movement, and determine distance.
More than our eyes can see.
All insects and arachnids. for example bees, centipedes, millipedes, spiders.
it may had 2 or more eyes.
becaus eour body is more complex than insects and worms....
They only have 2 eyes because they don't need any more than that but for spiders that's a different story they have 8 eyes but im not sure why they have 8!
Nothing really, but think about it. 2 eyes, 2 ears, 2 arms, 2 legs. it would just be unusual. why ask this, do you have 3?
No.
Crayfish have compound eyes, similar to many insects. These eyes are on stalks on the top of their head and allows them to see what is going on above them when they are in the bottom of a body of water.
