一直以来，人们都在设想如果地球发生大灾变，能够活到最后的一定是缓步动物门的生物，所以在某种程度上，气囊猫面棘甲熊虫的存在完全是可以理喻的。然而它的尺寸和行动方式呢？估计没什么人能猜到。 气囊熊虫在战斗中缓慢而笨重，所以在这末世生存下去，它选择了飞行。 首先，它会像气球一样迅速膨胀，这个过程能够相对持久但是会导致减速。然后通过腹部一系列肌肉工作将气体迅速排出，利用排出的气体将自己发射到空中的，这种方式同时也能减缓降落的速度。 是的，就是这种听上去很不可能的方式，但是气囊熊虫确实能够充分地利用它的膨胀性。除了跳跃，它还能利用储存起来的气体驱赶侵略者，甚至还可以帮助自己浮在水面上。
Common name: Gasbags
Species: Mopsechiniscus fluitobesus
It was always hypothesized that a member of the Tardigrada phylum would be the last species on Earth in the event of a global apocalypse, so in some ways, the existence of Mopsechiniscus fluitobesus is completely expected. Its size and method of travel, however? Less so. Mopsechiniscus is slow and ineffective in a fight, so to survive, it tends to choose flight - literally. First, it inflates itself like a balloon, briefly slowing down and gaining durability. Then it launches itself into the air by expelling gas through a series of sphincters in its underbelly, which it also uses to slow its descent. Yes, it's as...unusual as it sounds, but Mopsechiniscus makes the most of its inflatable nature. In addition to jumping, it can use its stored up gases to push back aggressors, or even float on water.
While a poor steed in battle, Mopsechiniscus is a fantastic beast of burden. The hairs on its back let a single rider steer it without a saddle, and it carries an incredible amount of cargo for its size. A small caravan of these could see us swimming in resources in no time.
