good or bad eye sight?

[ornata]

hey

Does any of you guys know if wandering spiders have good eye sight?

I know they cant compete with salticidae or lycosa, but if you compare them to huntsman spiders!?

Which two of them has the best eye sight, and how good is it?

Also want to ask about how good the eye sight to lycosa(wolf spiders) are, compared to jumping spiders, who has a excellent eye sight as we all know:)

[Brianhogs]

Even though wolfs have good eyesight for hunting, I have to say, jumpers have way better vision and have the ability to single out movement from very far away. Lycosidae do have a very keen sense of vibration, so I think that they would have worse eyesight than jumpers...

This is my OPINION.


I have no experience with huntsmans or wandering spiders.

Yes, wandering spiders have good eyesight. Even though they bear some resemblance to wolf spiders they aren't closely related. They are both active hunters that rely heavily on their eyesight and have much the same habits.

IMO huntsman's have better eyesight than wandering spiders and wolf spiders. They can detect approaching humans or other large animals from some distance. Plus being arboreal gives them a much better vantage point.

I would rank eyesight as followed:
jumping spiders
huntsmand spiders
wandering/wolf spiders

Are you sure that huntsman spiders have better eye sight then wolf spiders? I am not so sure about that!

Wolf spider have bigger eyes(compared to size), and can also detect approaching objects, like a human. They also use there eyes during the mating process.

Some studies have shown that some females/species prefer males with the "best" paterns

Can you please tell me your source?

[Skullptor]

Source? No. IMO stands for in my opinion.

I don't think the OP expected scientific data on this, because there probably isn't any.

It's kind of like asking which bird has better eyesight a robin or blue jay?

As stated, they all rely heavily on their eyesight and are long-sighted hunters. Your point about the wolf spider having larger eyes is a good one and may be the factor that disproves my opinion. I went with the theory that the huntsman's vantage point may tip the scales in it's favor.

I know that studies have shown *the male wolf spider will commence courtship of a female who is still centimeters away. But it can also be stimulated by pheromones or both visual and scent signals.

I think bigger eyes is a very "safe" astatmennt, but when you watch the behaviour of wolf and huntsman spiders, Lycosa seems to be more dependent on there eye sights......but of course, you may have right=)

No need to feel stupied!

I think bigger eyes is a very "safe" astatmennt though, it is a reason that nature gave them those big eyes.

When you watch the behaviour of wolf and huntsman spiders, Lycosa seems to be more dependent on there eye sights......I think!

But when it comes to your "spider eyesight list", so did you forget Net -casting spiders, they are almost at the same level ass jumping spiders(better night vision, I think)

cheers

Actually, I think I will mail Rick West about this question, his expertise goes beyonde mygalomorphaes...I hope!!!

[Skullptor]

Please post what he thinks!

[ornata]

Please post what he thinks!


This was his answer: "I would 'guess' so as I am no expert on araneomorph spiders".....crap, I really want to find out about this topic!!

hmm....is there any araneomorphae experts I can ask!!

[Skullptor]

Perhaps you could get a specimen of each and run some rudimentary tests yourself?

I think that one of the ATS officers, Robert Gale Breene III, was an arachnologist. Could well be that other directing members there are arachnologists, or experts otherwise, too. Likewise, you could look into the BTS members.

ATS: atshq.org.

I would love to hear if there is a scientific answer to this, too, although the speculation and reasoning is appreciated as well.
