Johan Christian Fabricius
A Danish zoologist, specialising in entomology. He was a student of Carolus Linnaeus in Uppsala (Sweden), and then appointed a professor at the University of Copenhagen (Denmark) as well as the University of Kiel (officially Germany, but ruled by the Danish king through a personal union). Fabricius is considered one of the most important entomologists of the 18th century, having named 9,776 species of animals, and established the basis for the modern insect classification. He added two distinct areas to the classification system: both artificial and natural characteristics. Artificial characteristics allowed for the determination of a species, and natural characteristics for the relationship to other genera and varieties. Much of his system still remains the basis of modern insect classification. Towards the end of his career Fabricius spent much of his time living in Paris, where he frequently met with naturalists such as Georges Cuvier and Pierre André Latreille.

How about replacing your dog with a Litoria caerulea? This frog's docile nature, cartoon-like appearance and long life expectancy make it an attractive choice for exotic-pet owners. The male calls can be heard year round from high tree canopy. When threatened, the Australian green tree frogs emit an ear-piercing distress call. During the dry season they cover themselves in a cocoon of sloughed epidermis and mucus and burrow to keep moist. When the rainy summer season comes they feast for a few days before starting to breed. The breeding often takes place in very moist places, such as drainage systems, water tanks, or grassy semi-permanent water systems. The female ejects her eggs with such a force that they pass through the male's deposited sperm cloud, stopping up to half a meter away. A clutch contains from 150 to 300 eggs. Once fertilized, the eggs sink to the bottom substrate and about 28 to 36 hours later hatching begins. Metamorphosis occurs in two to three weeks given good conditions. Litoria caerulea shares the genus Litoria with dozens of other frog species endemic to Australasia. One old common names of the species, "White's tree frog", is in honor of John White's first description in 1790. It was the first Australian frog to be scientifically classified.
