Nannarrup is a genus of soil centipedes in the family Mecistocephalidae. [1] [2] This genus contains only three species, including the type species Nannarrup hoffmani. [3]Also known as Hoffman's dwarf centipede, N. hoffmani was discovered in Central Park in New York City and was the first new species to be discovered in that park in more than a century. [4]
Hypopygus is a genus of South American gymnotiform knifefishes native to the Amazon, Orinoco and upper Paraguay basins, as well as rivers in the Guianas.

The Phillip Island centipede is known for its habit of preying on vertebrates including geckos, skinks, black-winged petrel (Pterodroma nigripennis) nestlings, and fish, as well as other small arthropods. [6] The centipede may consume petrel chicks at a rate between ~2100 and ~3730 nestlings per year, across the island's population of
Observations of the grumpy dwarfgoby indicate that it typically inhabits depths ranging from 10 to 30 metres (30 to 100 ft). This depth range is where the fish finds shelter among the holes and crevices among the walls, and overhangs of coral reefs, as well as access to various food sources, such as tiny invertebrates, which it will capture using its large canines.
The world's smallest fish depends on the measurement used. [1]Based on minimum standard length at maturity the main contenders are Paedocypris progenetica where females can reach it at 7.9 mm (0.31 in), [2] [3] [4] the stout infantfish (Schindleria brevipinguis) where females reach it at 7 mm (0.28 in) and males at 6.5 mm (0.26 in), [1] and Photocorynus spiniceps where males can reach it at 6. ...
