** The hiddenwood is the last species of ant tree left by the early Late Ultimocene after the ice age due to most of the plant growing underground. With the increased warmth and wetness of the Late Ultimocene and the extinction of the more destructive razorback thorngrazer, it has seen a major resurgence. It's also the last of the sunflower tree lineage found on Serinarcta, with its cactaiga cousin being among the victims of the increased temperatures.

* LifeWillKillYou: Blaze eventually dies from old age, surrounded by her family, save for Brighteye who happened to be away and only comes back once she's already been buried.

* BizarreSeasons: In the Hothouse Age, the climate is warm and wet all year round around the whole globe regardless of latitude, meaning that there are barely any seasons. The main exceptions are the Polar basin and the Longdark swap. Both of these biomes are situated in the polar circles and so have to deal with one season of constant daylight and another one of constant darkness...while still being warm in both.

* AmbushingEnemy: The cave chandelier is a centipedeweed adapted to cave environments that plants itself on ceilings and has its tendrils hang down to detect and ensnare unsuspecting prey, ranging from rat-sized to approaching human size.

* AquaticSauropods: The blimp is a non-cygnosaur gantuan that has evolved into a fully aquatic animal than [[WalkDontSwim walks]] along river bottoms like a hippo. It can travel on land when young, but by fifteen years of age, it is too large to leave the water and beaching can be fatal for them.

** Wideminds are seen as more flexible in thought by the woolly wumpos, and so young ones are venerated by elders due to their ability to change how things are done in ways that only they can.

** Played completely straight by the blimp. Unlike the ferocious cygnosaurs, the blimp is a docile animal that only attacks to defend itself. It's also the largest bird ever to live, with adults reaching lengths of 100 feet and a weight of 110,000 pounds.

* SeaMonster: Swordwhale fish such as the gulpy and gigadon, birdwhales, bloons, king trawlers, predator burdles, and giant filter-feeding dolfinches like the banded maw, the last of which are said to be the largest birds Serina has ever seen. Special mention goes to the sea rex of the ocean age. They're huge 50ft apex predators with crushing jaws and armored skin that makes them virtually unbeatable as adults, even to the pelagic daydreamers who are large powerful predators in their own right. This forces them to target the beasts when they are young and small when dwindling food supplies causes the fully grown sea rexes to start hunting the pelagans instead.

** The kraken of the late hothouse is an aquatic variant of the trope, being a colonial centipedeweed that covers the rocky shores of the Centralian Sea, ensnaring any animals unfortunate enough to swim into it, including animals up to the size of fully grown pied guingrebes if they swim inland while disoriented during storms. Its main limiting factors that prevent it from spreading are that it can't tolerate saltwater, grow on sandy shores, and while water resistant is not fully aquatic, so animals like the molrus can throw krakens into the sea to drown since they can't survive more than several days of submerging.
