Giant spider

A Giant spider is an introductory monster in RuneScape that fights with ranged attacks. They come in a variety of levels, and are weak to crush attacks, so a mace or warhammer will dispatch them quickly, although any melee weapon can be used. They have moderate resistance to ranged and high magic resistance, and will range the player right back if attacked with these styles, so training these skills on them is not advised.
Many new players kill the level 4 giant spiders to train combat because of their low combat level and close location to the starting point in Lumbridge. They primarily attack with ranged.
The level 48 spiders are rarely trained on, and are aggressive. They also use ranged in combat.
The level 57 Giant spiders are fairly accurate and can hit up to 74 LP if you have low defence, so it is recommended that players wear at least full rune armour and bring food (filling the inventory with food is recommended as the spiders drop nothing). Alternatively, members can bring a Bunyip, Saradomin Godsword, Unicorn Stallion, or a full set of Guthans to heal with. The level 57 Giant spiders have 1425 hp and fight with ranged. Unlike their level 4 and 48 cousins, however, they do NOT drop anything, not even charms.
There have been rumors circulating on the Internet of a spider large enough to eat people’s dogs and cats… While it should be obvious that such an animal would not be discovered out of the blue, and the poorly done photoshop job should be a hint, apparently many people have fallen for this. So I figured why not do a debunking and talk about something that I love, spiders.
To start with the photo, there are VERY clear signs that it was photoshopped, and poorly at that. And even if the photoshop had resulted in a masterpiece of deception, the image simply doesn’t make sense; the shape, body type, location, behavior, none of it.
More interesting than any of that though, is that there are real limits to how large spiders can actually get, based primarily on the (relative) ineffectiveness of their “lungs”, among other factors. They simply can’t grow past a certain size in relation to the oxygen content in the atmosphere, or they wouldn’t survive.
Most spiders possess what are called “book lungs“, which are completely unrelated to what we normally call lungs, and developed independently. And from fossil evidence, we can determine that these structures have remained more or less unchanged throughout the past 400 million years because of how effective they are. There are downsides/limits to them though, with relation to lungs as we know them. As body size increases in relation to gas molecule size, they become less effective. This means that as animals with these structures get bigger they become less and less effective at “breathing”, which places limits on their maximum size.

Other limits to their maximum body size include a decreasing effectiveness and durability of their exoskeleton and muscular system, as they get larger they generally need to become thicker to compensate for this (especially highly-mobile spiders), tarantulas are a good example of this.
The two largest spiders alive in the world today are both approaching the limits of maximum spider size, in the current atmosphere anyways, perhaps not in the distant past. They are the foot long Goliath bird-eater tarantula, and the Giant Huntsman in Vietnam. Neither of these come close to approaching the size of the “Angolan Witch Spider”.
