No, humans do not have feelers.
A bee's antennae (feelers) are their organs of scent detection -- many, many times more sensitive than a human nose. The are also organs of touch.
A butterfly does have feelers. These feelers are at the top of the butterfly's head. The feelers help it to feel its surroundings.
Mostly all insects have feelers. As we know that there are a large amount and types of insects in the world so I can not tell you the exact number.
a tarantula maybe have a feeler but it should not have one
crayfish have six antennae
Crayfish have a total of 5 swimmerets
a crayfish can have up to 100 babies.
The zygote of a crayfish with a diploid number of 112 chromosomes would contain 56 chromosomes. This is because the zygote receives one copy of each chromosome from each parent, resulting in half the number of chromosomes of the diploid number.
yes a ant has feelers witch are called Antena's.
