Tarantula, I'm sorry to be the one that has to break the news to you but you look dumb as fuck.

That's definitely not a horn. Spidey penis or weird head leg.

The new species of Ceratogyrus described here is remarkable. No other spider in the world possesses a similar foveal protuberance. The function of the foveal protuberance, or 'horn', in Ceratogyrus is uncertain. Members of other theraphosid genera from the Neotropics, namely Cyrtopholis Simon, 1892, Sphaerobothria Karsch, 1879 and Umbyquyra Gargiulo, Brescovit & Lucas, 2018, also possess similar foveal structures, as do some species of the ctenizid genus Stasimopus in South Africa, and several aganippine idiopid genera from Australia (M. Rix pers. comm.). The protuberance of C. attonitifer is unique in its length, as well as being soft, whereas this structure is fully sclerotized in all other genera where it is known to occur.

they dont know what it is

also its special because its flaccid instead of hard ( ͡° ͜ʖ ͡°)

Fucking spiders. They have to make even something as cool as a horn creepy and weird looking.

Looks like he's got some some of bizarre spider dick growing out of his head.

The tarantula is part of a secret society formed by only the most rich, smart and influential arachnids and the horn is really a hat because its going to its congregation

When the last eagle flies over the last crumbling mountain
And the last lion roars at the last dusty fountain
In the shadow of the forest though she may be old and worn
They will stare unbelieving at the last spidercorn
When the first breath of winter through the flowers is icing
And you look to the north and a pale moon is rising
And it seems like all is dying and would leave the world to mourn
In the distance hear the laughter of the last spidercorn
I'm alive, I'm aaaaaaaaaaaaaaaaaaaaaaaaallllllllllllliiiiiiiiiiiiiiiiiiivvvvvvvvvveeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

My first thought was that it looks like a leg tried to grow there. So weird.

It's sad do the other spider kids make fun of him and refuse to let him join in on their spider games?

Imagine if this is just the first few steps towards tarantulas evolving wings and flying into our faces.

I also love the term foveal protuberance.

this is apparently it's relative so you can see how the size of it is a novel

wikipedia says: There are several probable functions for this horn: according to a study by Rick C. West in 1986, it provides an increased surface for the attachment of the dorsal dilator muscle, which aids in drawing in liquefied food into the sucking stomach at a faster rate; this way, the spider can retreat to a safe place faster. It also increases the area for the midgut diverticula to expand during times of nutrient and water availability, analogous to a camel's hump, helping it to survive in its arid habitat during droughts.

Pretty neat that stuff is still being discovered.

every year there is a new study or two saying we have somewhere between like 2% and 30% (depending on a lot of factors) of the planet's species cataloged so its pretty safe to say we have a while to go on new stuff being discovered

for example these guys say
There are probably 303 species of mammals left to be discovered by science, most of which are likely to live in tropical regions, according to a predictive model developed by a team of University of Georgia ecologists.

thats just mammals

we have millions of arthropods to go at the very least

this paper: http://www.environment.gov.au/science/abrs/publications/other/numbers-living-species/introduction
says we describe about 18,000 new species a year out of a total somewhere between 5 and 50 million total species

How dare you think the horn is weird. It's not its fault it was born like that. For shame.
