Dawn of Biological Accuracy

I have a confession to make. As an arachnologist, I have a lot of fondness for Spiderman. This webslinging hero does more for the image of my chosen species than any amount of science communication ever could. However, ever since I was a kid, my favourite superhero has been Gotham’s Dark Knight, the Caped Crusader…Batman. Which is the better superhero? Who would win in a fight? There’s really no way to know, but what we can figure out is which of these animal themed heroes represents their namesake best. Through this contest I will compare these two juggernauts of the genre and determine in a totally scientific and unbiased manner who is the most biologically accurate superhero! Grab your grappling hooks, it’s time for Batman vs Spiderman: Dawn of Biological Accuracy.

Round 1: Anatomy/Appearance

Basically, the question here is, who mimics their animal’s body the best? Now, clearly Batman is at something of an advantage here, by choosing an animal with the same number of legs as him…but let’s try and give Spidey a fair chance.

Spiderman does share a lot of biological characteristics with spiders. “Spiderman” 2002 clearly show his ability to climb walls comes from hooks and hairs on the ends of his limbs, and this version even has web-producing organs. However, it really does come down to that question of limbs, doesn’t it…and spiderman simply doesn’t have enough. “But Simon”, I hear you cry “Both Superior Spiderman and Tom Holland’s MCU Spiderman have robotic extra arms, bringing them up to 8 limbs! Surely that’s the right number!!” Well, whilst I thank you for the specificity of your references dear reader, you are incorrect. Spiders actually have 10 limbs (sort of). Next to their mouth, spiders have a pair of appendages known as pedipalps. Whilst small, they do look a lot like legs (in females at least) and are sometimes referred to as limbs. Spiders can use them for all sorts of things, usually handling food, though some females use them to carry their eggs around with them. Male spiders also house their genitals inside these pedipalps! In scorpions, these pedipalps actually make up the claws! So, in summary, Spiderman really should have 10 limbs, not 8. Batman on the other hand is the clear winner. He usually has bat-like wings and ears. He is “warm blooded” like a bat, and thanks to evolution, the bones in Bruce Wayne’s arm are the same as the bones in a bat’s wing…just shaped a little differently.

Batman 1 – 0 Spiderman

Round 2: Abilities

Using their gadgets and powers, who can mimic their animals abilities the best?

This is where I must confess, I am not a bat scientist, so there may be some flaws in my analysis. However, Batman seems to be doing VERY well in this round. Bats are known for their abilities of flight, hearing/echolocation, and hanging upside down. Many versions of Batman can at least glide, and in “Batman Begins” and “The Dark Knight” we see him using gadgets to enhance his hearing and create images using sonar. In “Batman” 1989 and the Arkham video games, we even see Batman hanging upside down for long periods. However, is he as good as a bat? Could a gliding batman catch a moth in his mouth? Could he fly from a cave with thousands of other batmen and not crash into them? Unlikely.

Spiderman also does well here. As mentioned, he can create webs, climb on walls, and from trying to catch spiders I can tell you that they share his Spidey Sense. He also has “the proprtional speed and strength of a spider”, which depending in which spider you choose is probably accurate (though I once calulated that if he could run as fast as a Dolomedes spider, he should be able to run at over 200kph).

However, for this round, I’d like to discuss an underated ability of spiders: geometry. To build orbwebs, spiders have the incredible ability to construct a complex geometric shape in 3D space and modify its design to suit their environment! This is a kind of intelligence we don’t usually think about in animals…but it’s an intelligence Peter Parker possesses. In “Spiderman: No Way Home” Spiderman battles Doctor Strange in the Mirror Dimension. How does he win? He realises the Mirror Dimension is “just geometry, you’re great at geometry” and catches the sorcerer supreme in a web. So yes, Spiderman wins this round because Peter Parker is a geometry nerd.

Batman 1 – 1 Spiderman

Round 3: Villains

Any C-list superhero will tell you that a hero is only as cool as his villains…but do the villains that that Batman and Spiderman face represent the natural enemies of their animals? Well, let’s go through some of their most popular villains and see what we can find.

Batman: The Joker (nope), The Riddler (whilst bats are probably bad at Riddles…no), Bane (no), Scarecrow (…hmmmm, no), Two Face (Bats have very few rights in the legal system), Poison Ivy (maybe…), Catwoman…ah hah!! Right here in Aotearoa cats are a threat to our endangered bats!

Spiderman: Doctor Octopus (Octopuses don’t meet many spiders, I don’t think),The Green Goblin (give me a break), Mysterio (oh, that hologram loser), Sandman (NO), Electro (…not really), The Lizard (Yes!). As relatively large vertebrates, lizards would definitely love eating spiders!

So both heroes have at least 1 villains who would be a threat to their animal of choice. BUT…is Catwoman really a villain? The Lizard actually tries to kill and eat Spiderman most of the time…so I will give the point to Spiderman here!

Batman 1 – 2 Spiderman

Spiderman wins! He is officially the most biologically accurate hero!

Batman is still cool tho.

“You just end up with a sixth sense for where your species will be.”, said my supervisor nearly three years ago. As with most things, Chrissie ended up being right about this (and I’m not just saying that because her website hosts this blog)! My PhD work has had me travelling up and down the country hunting for two spider species.

In some cases, this meant arriving in a remote part of the South Island, with only 7 days to collect hundreds of spiders from sites I had never been to before! The first time I tried this, I struggled. I wandered up and down field sites with no idea what I was looking for. Hours upon hours of my precious time wasted in places with the same number of spiders you’d find on the surface of the Moon! However, three years on, having learnt the hard way, I have developed that sixth sense that Chrissie spoke of, my Spidey Sense, if you will.

Looking at a site, I can tell you whether you will find my target species there. The terrain, elevation, the structure of the plant species, these all provide useful information. However, it’s all in a way that is difficult to describe. For example, I can tell you that Dolomedes minor likes shrubby habitats, and that Dolomedes aquaticus likes rocky rivers. I can also tell you that aquaticus needs rivers with a little elevation and plant life to them, so they don’t all get washed away in the first bit of rain. But there’s also a certain ineffable quality. Something unquantifiable that exists in a good site. Something that reaches out into the subconcious part of my brain and whispers “there are spiders here.” In the same way that Spiderman knows that danger is nearby but can’t tell you what, I can tell you that spiders are nearby…but can’t tell you why.

This spidey sense has also completely ruined my brain! I can’t go for a walk without seeing a patch of shrubs that I know must teem with spiders. I see a picture of a riverbend, and I know the precise spot where I’d look for eight legged friends! I simply cannot turn off this knowledge. There is only so many times my friends and loved ones want their relaxing walks interrupted by the words “I reckon there’s spiders in that bush.”

And now here is the dilemma. I will not be the last to carry this (modest) burden. Even now, I am helping train an intern to find another species of spider. And after him, there will be other students and PhD candidates. If I myself am to continue in this field, I may yet have to develop my senses to look for more species. Should they be cursed…as I have been.

I mean probably, I am being quite melodramtic here… but if…with great power comes great responsibility, then perhaps with great knowledge comes great annoyance.

Bonjour everyone!

My name is Bastien Clémot, I’m a 21-year-old Msc student, coming from France to learn more about scientific research and Arthropod behaviours! I will roam the lab corridors under Chrissie’s supervision till late June (Which is a quite short time, unfortunately). My primary objective here is to study the courtship and reproductive behaviours of nursery web spiders, but also to make some observations on Dolomedes dondalei, a species that everyone succeeds to find but me! (Love spiders and they’ll love you back, they said) Overall, I’m mainly interested in evolutionary and behavioural ecology in Arachnids, but also in applied modelisation.

Apart from my obvious passion and fascination for those cutey-crawlers (who said ‘creepy’?), I might be a blend of a nerd, enjoying fantasy worlds, writing, role-playing, coding, and video games; and a nature lover, always eager to go hiking, bouldering, making wildlife observations and naturalist drawings! But globally I think that it’s just an unexhaustive list, as I tend to have spontaneous interest in everything.

Coming to New Zealand is a huge adventure and step in my life. I’m truly enjoying discovering new habits and new ways of thinking, as much in science as in everyday life! Of course, as a proper tourist, I’m loving discovering Maori culture and New Zealand’s landscapes and environments. By the way, I should give an honourable mention to feijoas, which have been a revelation in my life and I think have claimed the top spot on my list of favourite fruits! (Is this excessive? No. Nothing is too much for feijoas)

Besides that, one of my nature lover objectives in New Zealand is to see a peripatus, which might not gonna happen, but wish me luck! In all cases, my plan here is mainly to go hiking everywhere and live my life in Hamilton, by taking all opportunities and having fun!

Anyway, you’ll most likely find me between my desk and the lab, where I feed my beloved spiders. So don’t hesitate to have a talk with me! 😉
