Animal Photo Albums and Classification

My Animal Photo Albums feature images of unrestrained animals that I photographed in their natural or adopted habitat. Furthermore, I generally excluded photos of animals that depend on humans for food, such as those in captive zoo type environments.

The estimated number of animal species on the planet is 8.7 to 15 million. Still, science has only identified around 1.6 million of these.

Animal Photo Albums Invertebrates

The invertebrate photo album collections feature animals that belong to the phylum Arthropoda (Arthropods):
(a) Insecta (Insects),
(b) Arachnida (Arachnids), Araneae (Spiders).

Insecta (Insects)

Insecta (Insects) are the most diverse animals globally, with over one million described species. These include around 180,000 Lepidoptera (Butterflies and Moths) and over 6,000 Dragonflies and Damselflies (Odonata). Other insects such as Ants, Bees, Crickets, Grasshoppers, Mayflies, Stick Insects, and True Bugs account for the rest.

The photo album collections feature a small selection of images arranged in four time-ordered evolutionary history groups:
(a) Mayflies, Dragonflies and Damselflies,
(b) Moths,
(c) Butterflies:
(i) Gossamer-winged,
(ii) Brush-footed,
(iii) Skippers, Whites and Swallowtail,
(d) Other Modern, Wing-folding Insects.

Arachnida (Arachnids)

The number of described Arachnida (Arachnids) species is over 100,000; about half this number is Araneae (Spiders).

The photo album displays Araneae (Spiders) images placed in Arachnida (Arachnids), which show dorsal and ventral views, feeding behaviours, and different forms of spider webs.

Animal Photo Albums Vertebrates

The vertebrate photo album collections display the following animal classes placed in the phylum Chordata, subphyla Vertebrata:
(a) Reptilia (Reptiles),
(b) Mammalia (Mammals).

Reptilia (Reptiles) and Aves (Birds)

Class Reptilia (Reptiles) and Aves (Birds) share a common ancestor. Although Aves is part of Class Reptilia, my Bird Photo Albums feature in a dedicated top-level Birds section at the same level as animals.

The reptile database contains more than 10,000 species and 2,700 subspecies. My five time-ordered evolutionary history photo albums display a small selection of reptile images:
(a) Crocodiles, Turtles and Tortoises,
(b) Lizards, Skinks and Geckos,
(c) Iguanas (Land, Marine and Tropidurid),
(d) Iguanas (Agamids and Anoles),
(e) Snakes.

Mammalia (Mammals)

There are around 6,500 recognised mammal species. The ‘IUCN Red List 2020-2’ of Threatened Species lists 5899 while the Animal Diversity Web (ADW) 2013 and Mammal Species of the World, 3rd edition 2005 database lists around 5,000 species.

The mammals’ photo album displays some images arranged in four time-ordered evolutionary history groups:
(a) Egg-laying and Marsupial Mammals,
(b) Colugo, Primates, Rabbits and Rodents,
(c) Cetaceans and Marine Carnivores,
(d) Land Carnivores, Ungulates and Bats.

Animal Photo Albums High-level Classification and Photo Album Collections

The figure shows a simplified taxonomic diagram in time-ordered evolutionary history that illustrates the arrangement of a high-level classification of Animalia (Animals).

Following this classification arrangement, I have split the photo album collections into invertebrate and vertebrate groups:

Invertebrates contain two photo album collections:
(1) Insecta (Insects),
(2) Arachnida (Arachnids).

Vertebrates contain the following photo albums:
(1) Reptilia (Reptiles),
(2) Aves (Birds),
(3) Mammalia (Mammals).
