Myriapods are terrestrial arthropods with elongated, segmented bodies bearing numerous legs. This group includes centipedes and millipedes, which are commonly found in soil, leaf litter, and under stones or logs. Most myriapods play an important role in ecosystems as predators or decomposers. Classes of Myriapods Myriapods are divided into four main classes: Class Diplopoda — … Continue reading "Subphylum Myriapoda — Centipedes & Millipedes"

Superclass Multicrustacea — Typical Crustaceans
Multicrustacea is a major group of crustaceans that includes many of the most familiar forms such as crabs, lobsters, shrimp, woodlice, barnacles, and copepods. Members of this group occupy a wide range of habitats, from oceans and freshwater to land. It is divided into two main classes: Malacostraca, which contains the larger and more recognisable … Continue reading "Superclass Multicrustacea — Typical Crustaceans"
Read MoreSubphylum Chelicerata — Spiders & Relatives
Chelicerates are a major group of arthropods that includes spiders, scorpions, mites, ticks, horseshoe crabs, and sea spiders. Unlike many other arthropods they lack antennae and possess specialised mouthparts called chelicerae, which are often adapted as fangs or pincers used for feeding. Most chelicerates are terrestrial predators, although some groups remain marine. Chelicerates occur in both marine and … Continue reading "Subphylum Chelicerata — Spiders & Relatives"
Read MoreClass Reptilia: Order Squamata — Lizards and Snakes
Squamates are the most diverse reptiles, including lizards, snakes, and amphisbaenians. With more than 11,000 species worldwide they occupy habitats ranging from deserts and forests to grasslands, wetlands, and even the open ocean. Their diversity is reflected in their anatomy, behaviour, and ecological roles, from tiny geckos to large constrictors and venomous vipers. Familes of … Continue reading "Class Reptilia: Order Squamata — Lizards and Snakes"
Read MoreOther Mammal Orders
The mammals on this page belong to a few other groups that I have only encountered occasionally. These include sloths in the tropical forests of Central and South America, opossums in the Americas, and some familiar insect-eating mammals from Europe such as hedgehogs and moles. Order Pilosa — Sloths and Anteaters Kingdom: Animalia > Phylum: … Continue reading "Other Mammal Orders"
Read MoreOrder Lagomorpha — Rabbits, Hares and Pikas
Kingdom: Animalia > Phylum: Chordata > Class: Mammalia > Order: Lagomorpha These are small to medium-sized herbivorous mammals found across much of the world, particularly in open landscapes such as grasslands, mountains and deserts. They are characterised by long hind legs adapted for running or jumping and by having two pairs of upper incisors — … Continue reading "Order Lagomorpha — Rabbits, Hares and Pikas"
Read MoreOrder Chiroptera — Bats
Kingdom: Animalia > Phylum: Chordata > Class: Mammalia > Order: Chiroptera This is the second-largest order of mammals after rodents. Bats are the only mammals capable of true powered flight, using wings formed from a thin membrane stretched between elongated fingers. Most bats are nocturnal and use echolocation to navigate and locate prey in the … Continue reading "Order Chiroptera — Bats"
Read MoreOrder Primates — Primates
Kingdom: Animalia > Phylum: Chordata > Class: Mammalia > Order: Primates Primates include monkeys, apes, lemurs and their relatives. They are generally characterised by forward-facing eyes, flexible hands and feet with grasping digits, and relatively large brains compared with other mammals. Most species live in tropical forests and spend much of their time in the … Continue reading "Order Primates — Primates"
Read MoreFish — Several classes
Fish are treated here as a practical grouping of aquatic vertebrates across several classes rather than a single formal taxonomic unit. These include the ray-finned fishes, lobe-finned fishes and the cartilaginous fishes (sharks, rays and chimaeras), as well as the more primitive jawless fishes such as lampreys and hagfishes. Despite their diversity, these animals share … Continue reading "Fish — Several classes"
Read MoreClass Reptilia — Reptiles
Reptiles are ectothermic vertebrates characterised by dry, scaly skin and reproduction typically involving shelled eggs laid on land. They evolved from amphibian-like ancestors over 300 million years ago and today include crocodilians, turtles, lizards, snakes, and the tuatara. Orders of Reptiles Modern reptiles are divided into four living orders, ranging from the ancient tuatara lineage … Continue reading "Class Reptilia — Reptiles"
