Lonesome George
Lonesome George was a male Pinta Island tortoise and the last known individual of the species. In his last years, he was known as the rarest creature in the world. Over the decades, all attempts at mating Lonesome George had been unsuccessful, due to the lack of females of his own species. This prompted researchers at the Darwin Station to offer a $10,000 reward for a suitable mate.
Giant ant colonies
Anthills can be fairly unassuming on the surface. When excavated, not so much.
Immortal jellyfish
The immortal jellyfish is found in the Mediterranean Sea and in the waters of Japan. It is one of the few known cases of animals capable of reverting completely to a sexually immature, colonial stage after having reached sexual maturity as a solitary individual. Once the adults have reproduced, they don’t die but transform themselves back into their juvenile polyp state. Their tentacles retract, their bodies shrink, and they sink to the ocean floor and start the cycle all over again.
Shagreen

William Buckland
William Buckland is famous for two things: he was the first man to write a full account of a fossil, and he was incredibly eccentric when it came to animals and food. Buckland’s love of natural history resulted in his house being something akin to a zoo. He filled it with animals of every kind and he then proceeded to eat them all (and serve them to guests). He claimed to have eaten his way through every animal. The creatures that he said tasted worst were bluebottle flies, and mole. Various guests to dinner describe being served panther, crocodile, and mouse.
Shad roe
Shad roe is the egg sac of the female American shad fish, a member of the herring family. Each female shad produces a pair of lobe-shaped egg sacs. Although the fish itself is quite bony, shad roe is full of rich flavor similar to sweetbreads.
