Smallest Animals on the Planet

A list of the world’s smallest creatures according to their kind.

To become a world record holder, one must be the largest, the smallest, the quickest, and many other superlative capabilities and traits. On this article, let’s all see the world’s smallest creatures according to their kind.

Kitti’s Hognosed Bat (Craseonycteris thonglongyai)

Kitti’s Hog-nosed Bat also known as Bumblebee Bat of Thailand and Myanmar is considered as the smallest mammal in the world. This animal can grow up to 40 mm in length and weighs up to 2 grams only.

Etruscan Shrew (Suncus etruscus)

The Bumblebee Bat is small but the Etruscan Shrew or Etruscan Pygmy Shrew lighter and weighs up to 1.3 grams only making it the smallest mammal by mass. It measures 36 mm or 1.42 inches long with 40 mm length of the tail. This creature has a lifespan of 15 months and inhabits forests and brush areas between Southern Asia and Southern Europe.

Dicopomorpha echmepterygis

The male of this parasitic wasp can be as small as 139 μm long – it is regarded as the smallest species of all known insects. It is smaller than a single-celled paramecium. Females are 40 percent larger than the male. This parasitic wasp is blind and wingless. The adult males mate with their sisters inside the host egg, and die without ever leaving the egg.

Paedocypris progenetica

Paedocypris progenetica of Indonesia is the smallest known vertebrate in the world. It dwells in peat swamps and can survive extreme drought in part due to its small size which is just 7.9 mm long at maturity. Much of its habitat is acid water, with pH as low as 2.9. This species and other members of the genus are thought to be highly endangered.

Monte Iberia Eleuth (Eleutherodactylus iberia)

At 9.6 to 9.8 millimeters long, the Monte Iberia Eleuth and the Brazilian Gold Frog are tied as the smallest frog, amphibian or tetrapod. The Monte Iberia Eleuth was first discovered in 1996 on Mount Iberia, from which the animal gets its name, and exists in only two small regions of Cuba. Much remains unknown about this small creature.

Brazilian Gold Frog (Brachycephalus didactylus)

Adult Brazilian Gold Frogs measure to only 9.8 millimeters in body length. Many have a beautiful golden color, for which they are named. It is also known as Izecksohn’s Toad.

Speckled Padloper Tortoise (Homopus signatus)

The world’s smallest turtle is the Speckled Padloper Tortoise of South Africa. The males’ measure 6-8 cm or 2.3-3.1 inches while females’ measure up to almost 10 cm or 4 inches.

Cuvier’s Dwarf Caiman (Paleosuchus palpebrosus)

At a maximum length of 1.6 meters or 5 feet long, the Cuvier’s Dwarf caiman is the smallest crocodilian. The Cuvier’s Dwarf Caiman or Musky Caiman is found in Bolivia, Brazil, Colombia and other South American countries.

Bee Hummingbird (Mellisuga helenae)

The Bee Hummingbird is the world’s smallest bird species and the smallest warm-blooded vertebrate. It is called the Zunzun in its native habitat on Cuba and the Isle of Youth. It has a mass of about 1.8 grams. This amazingly small bird’s wings beat 80 times per second and up to 200 times when mating. It is said to eat half its total body mass and drink eight times its total body mass each day. Its nest is 3 cm across.


Microraptor is the smallest known non-avian dinosaur. It is a genus of feathered dinosaurs that lived in China during the early Cretaceous Period about 130-125.5 million years ago. Adult specimens range from 42-83 cm or 1.4-2.7 ft long and the weight has been estimated at up to 1 kg or 2.2 lbs.

    I think the frogs are cute. I thought I saw some before, but being they are not native to this area I must be mistaken, unless they were in an exhibit some where. Great article, Nobert. Keep up the good work.
