21. The Devil’s Hole Pupfish!!!
It’s a critically endangered fish, measuring about 1.2” (30mm) they live in an isolated body of water in the Devils Hole in Nevada. The water temperature is consistently 91 degrees (33*C), which is very warm for most fish.
Devil’s Hole is a water-filled cavern stretching into a rocky hillside at an elevation of 2,400 ft, (730m) Devil’s hole is over 430 feet deep (130m) and connected to a massive underground aquifer below that- but the Devil’s Hole Pup Fish only occupy the upper 80ft of Devil’s Hole. It gets much much smaller than that!
They primarily eat, live and spawn on a small shelf measuring just 11×16 ft (3.5x5m) with a total area of 176sqft (17.5 m). They have been living in this shelf, as an isolated species for up to 60,000 years!?!
They were discovered in 1930, and since then have faced many trials, agriculture trying to drain the water, vandalism, and outright attacks. They are now surrounded by protective fences and surveillance.
Since 1972 (200 fish) the population spiked at 550 in 1995, but then saw a slow decline- at its lowest count in 2013 it was down to only 35 individuals. Thankfully it’s back up as of 2019 to 136 individuals. There have been multiple attempts at conversation even going so far as to build an exact replica of the Devils Hole 22ft deep! (6.7m) and have raised many fish there.
They have a very fascinating history, and remain largely a mystery. For such a tiny fish- millions have been spent on conversation efforts and protections, legal battles, and defense. I think it’s all completely worth it, they are the single most endangered fish on the planet and are completely unique to the Devil’s Hole.

22. There is a whale named 52-Hertz also known as the world’s loneliest whale. This whale is on a different frequency than any other whale. So it has most likely never heard another whale before.

25. Bob Ross was a Drill Instructor. When he stopped working as that, he promised he would not raise his voice at someone again. That’s why he was so soft-spoken.

28. Picking up a turtle by gripping it from the sides is said to be painful for the turtle. This is because turtles are attached to the insides of their shells, and you’re basically letting the weight of the turtle’s body hanging from the upper half of the shell. Instead, the proper way to pick them up is to support them from the bottom of the shell.

29. As the result of a collision with another moon eons ago, Neptune’s moon “Triton” has a retrograde orbit; meaning an orbit in the direction opposite to its planet’s rotation. Triton is the only large moon in our solar system to have such an orbit.
The collision eons ago also altered Triton’s orbit of Neptune in another, far more sinister way. Despite obviously emerging victorious from the collision, the impact ever so slightly threw Triton off course. Every year, Triton creeps a fraction of an inch closer to Neptune.
This means that one day billions of years in the future, Triton’s orbit will get too close to Neptune, and Neptune’s superior gravitational pull will tear Triton apart.
