Do Spiders Have Antennae

Do Spiders Have Antennae??

In summary, spiders don’t have antennae but only have pedipalps (palps) – which are a pair of appendages located at the front of their legs.

With no antennae, the spider’s legs are sensitive and specialized setae are put on their legs to pick up air currents, vibrations, sounds, and scents. 

Spiders have 8 legs (with up to 7 segments – the tarsus, metatarsus, tibia, patella, femur, trochanter, and coxa) for walking plus 2 pedipalps. See top spider killers.

Most spiders have three claws (with a smaller middle one) except for hunting spiders that have just 2 claws and the Australian crab spider that have no claws. 

Spider anatomy

Details: Do Spiders Have Antennae?

The spider’s pedipalps will come with about six segments but have no metatarsus. The male spiders have a modified palp (palpal bulb) that’s suited for mating. 

The pedipalps’ basal areas (coxae) sits near the mouth and will a8id eating – also named as maxillae but do not math the mandibulate arthropods’ maxillae

So, spiders lack antennae but just two appendages (pedipalps) around the animal’s mouths – you may confuse these with antennae on insects. 

The pedipalps serve specialized functions or manipulating the prey. Their chelicerae have fangs that can inject venom and also has eight legs. 

In fact, all arachnids including spiders lack antennae and wings, and their body has two segments – the opisthosoma (abdomen) and the cephalothorax (prosoma). 

Do spiders have feelers?

Spiders have pedipalps – (sensory feelers for food tasting) that appear like short legs at the front end of the spider. Many of the spider species have 8 eyes, but some none or up to 12 eyes.

The spider’s silk is released on their spinnerets areas – and you’ll find them around the arachnid’s abdomen tip.

What’s the spider’s Palp? – The spider’s palpi, palps, or Pedipalps are another pair of the arachnid’s chelicerates-appendages, also found in sea spiders, horseshoe crabs, and scorpions.

You’ll find the spider’s pedipalps being laterally positioned to the arachnid’s “jaws” (chelicerae) while also being anterior to its one pair of legs.

Spider’s Cephalothorax and Chelicera? 

The cephalothorax of the spider is one of the major parts (the anterior one) of the arachnid. The insects’ body parts are the abdomen, thorax, and head. 

On the front end of the spider’s cephalothorax, you’ll find a chelicera pair – the claw-like and fan-like mouthparts – appendages. The hollow chelicera has venom glands – for injecting into the prey. 

The pair of pedipalps (palps) at the front end of the cephalothorax – while the male spiders have their palp ends created to form mating parts.

Wolf Spider Body Parts?

The spider’s silk-producing glands are positioned on the rear-end of their Abdomen. Also, to prevent web-sticking, the spiders have oil glands to generate such oil. 

The arachnids have hair-covered legs – these will pick smells and vibrations on the air. The end of the spider’s legs has 2 tiny claws while also having 48 knees (on its eight legs). 

Spiders lack a skeleton but have an exoskeleton – a harder outer shell – and thus it won’t grow inside the spider. Therefore, spiders require to mold (shed) from their exoskeleton when young. 

After molting, the young spider will stretch its body before the new exoskeleton hardens – additional room for growth. But female spiders are bigger compared to males. 

Why Spiders Aren’t Insects?

The pink rose spiders come out during Halloween – maybe it cant scare many things but just hoverfly or sweat bee.

Just like insects, spiders are classified as invertebrates – seen at the Museum of Entomology

  • Unlike spiders, different insects have thorax, abdomen, thorax (with 6 legs), and head – also, they have mouthparts, antennae, and eyes – with a hard exoskeleton covering them.

Spiders, on the other hand, have a combined thorax and head into their body (the cephalothorax) plus their abdomen. Other bugs in this category include scorpions, mites, and ticks. 


On the question, do spiders have antennae? Well, NO, spiders have no antennae – but have a pair of pedipalps (small appendages) near their mouth that serve the same function.
