What is the Species Explorer?
The Species Explorer is SpeciesWatch.io's searchable index of conservation profiles. Every card on this page represents one species with a fully curated profile: its scientific name, common name in English and Spanish, IUCN Red List category, population trend and, when available, a distribution map built from real occurrence records and field recordings you can listen to. The View profile link opens the complete dossier — hero image, conservation status explained in plain language, estimated population, main threats, a map of recorded occurrences and references for further reading.
The search box understands scientific names (full or partial, e.g. Balaenoptera), common names in English or Spanish (vaquita, tortuga laúd) and genus names. The sidebar refines results by IUCN category, by continent — computed from the coordinates of recorded occurrences — and by audio availability, so you can instantly see which species have field recordings in our sound archive.
A curated collection — why not every species on Earth?
Quality over quantity. The Explorer grows through a hand-curated collection of flagship species instead of an unverified dump of tens of thousands of names. Each profile is checked by hand: current IUCN category and population trend, estimated population, main threats, translations and media. A collection where every card is complete and trustworthy is more useful — to you and to search engines — than a large one full of empty shells.
The collection was also chosen to exercise everything the Explorer can do: it spans the full IUCN scale, from Critically Endangered to Extinct in the Wild and Extinct; it covers marine, forest, savanna, mountain and freshwater habitats across all continents; and many profiles carry occurrence maps and audio. New species are added on a regular cadence through the same pipeline that keeps occurrences and recordings fresh, so the collection grows without ever shipping unverified profiles.
Meet a few of the residents
Among them: the vaquita (Phocoena sinus), the world's rarest marine mammal, with fewer than ten individuals left in the Gulf of California. The blue whale (Balaenoptera musculus), the largest animal that has ever lived, still recovering from whaling. The leatherback sea turtle (Dermochelys coriacea), the deepest-diving and most wide-ranging of all sea turtles. The whale shark (Rhincodon typus), the gentle giant of tropical seas and the largest fish on Earth. The European sturgeon (Acipenser sturio), a river giant nearly lost to dams and overfishing. The wandering albatross (Diomedea exulans), the bird with the greatest wingspan, threatened by longline fisheries.
Green sea turtle (Chelonia mydas), a seagrass gardener whose rookeries are slowly rebounding. Giant panda (Ailuropoda melanoleuca), the rare conservation success story of this list, downlisted from Endangered to Vulnerable in 2016. Scarlet macaw (Ara macao), a flamboyant Neotropical parrot still widespread but pressured by the pet trade. Spix's macaw (Cyanopsitta spixii), extinct in the wild and returning to Brazil only through captive-breeding and reintroduction programmes. African savanna elephant (Loxodonta africana), the largest land animal, declining under poaching and habitat loss. Tiger (Panthera tigris), the apex predator of Asian forests, whose wild numbers are slowly ticking upwards for the first time in a century.
How to read the IUCN Red List categories
The International Union for Conservation of Nature (IUCN) sorts every assessed species into one of nine categories. Extinct (EX) means no individuals remain; Extinct in the Wild (EW) survives only in captivity; Critically Endangered (CR), Endangered (EN) and Vulnerable (VU) form the threatened block, in decreasing order of extinction risk; Near Threatened (NT) is likely to qualify soon; Least Concern (LC) is widespread and abundant; Data Deficient (DD) has too little information for an assessment. The coloured badges and filters on this page follow that scale exactly, from red (CR) to green (LC).
Where the data comes from
Conservation statuses, trends, population estimates and threats are curated into our database from the IUCN Red List. Distribution points use OBIS for marine records and GBIF as global coverage for terrestrial and freshwater species. Field recordings come from xeno-canto, the world's largest archive of wildlife sounds. Encyclopaedic summaries are adapted from Wikipedia. Everything is cached on our servers and refreshed on a schedule, so providers are never stressed and you always see consistent, citable data.
