# Red Sea Creatures > Field guide to the marine life of the Red Sea: 1337 documented species across 5 top-level groups, plus 64 dive sites, 34 dive centres and 132 articles. Written and maintained by divers; species data is cross-checked against WoRMS and the IUCN Red List. The whole catalogue is also available as one document: https://redseacreatures.com/llms-full.txt — every category and species page concatenated, about 3 MB. Fetch it if you want the corpus in one go; otherwise read the per-page twins described below. Every catalogue and blog page has a plain-markdown twin for machine reading. The URL is the page URL with the section prefixed by `/markdown`: - `https://redseacreatures.com/taxon/fishes/bony-fishes/moray-eel` → `https://redseacreatures.com/markdown/taxon/fishes/bony-fishes/moray-eel` - `https://redseacreatures.com/blog/` → `https://redseacreatures.com/markdown/blog/` The markdown copy carries the same facts as the page: quick facts (size, depth, diet, habitat, hazard, IUCN status), the identification marks, the full description, and — on a category page — its subcategories and species list. Each one declares the HTML page as its canonical URL. ## Catalogue - [Fishes (Pisces)](https://redseacreatures.com/taxon/fishes): 775 species — Fish is not one group: the gap between a shark and a grouper is older than the gap between you and a bird. What they share is a gill that strips more oxygen from water than your… - [Invertebrate](https://redseacreatures.com/taxon/invertebrate): 539 species — Invertebrate names animals by a bone they lack, the way non-elephant would name them by a missing trunk. It covers more than thirty phyla, and the gap between a sponge and an… - [Mammals (Mammalia)](https://redseacreatures.com/taxon/mammals): 13 species — Inside a dolphin's flipper are the bones of a hand, fingers included. Marine mammals never finished the return to water: they breathe on purpose, sleep one half of the brain at a… - [Reptiles (Reptilia)](https://redseacreatures.com/taxon/reptiles): 6 species — A reptile kidney cannot make urine saltier than the sea, so every marine reptile grew a separate salt pump. A nesting turtle's tears are that pump working: concentrated brine, not… - [Sea plants](https://redseacreatures.com/taxon/sea-plants): 4 species — Sea plants is a gardening word for two unrelated things. The real split is plumbing: a seaweed has no roots or vessels and trades with the water cell by cell, while seagrass and… - [Creatures A–Z](https://redseacreatures.com/creatures-list): flat index of every species in the catalogue ## Diving - [Dive sites](https://redseacreatures.com/diving/dive-sites): 64 sites with depths, conditions and what lives there - [Dive centres](https://redseacreatures.com/diving/dive-centers): 34 centres, liveaboards and guides - [Red Sea overview](https://redseacreatures.com/redsea): the sea itself: geography, seasons, conditions ## Writing - [Blog](https://redseacreatures.com/blog): 132 published articles on marine life, diving and conservation - [Glossary](https://redseacreatures.com/vocab): marine biology and diving terms explained in plain language ## Optional - [sitemap.xml](https://redseacreatures.com/sitemap.xml): index of all sitemaps - [sitemap-taxons.xml](https://redseacreatures.com/sitemap-taxons.xml): every category page - [sitemap-creatures.xml](https://redseacreatures.com/sitemap-creatures.xml): every species page - [sitemap-posts.xml](https://redseacreatures.com/sitemap-posts.xml): every article - [About](https://redseacreatures.com/about): who maintains the site - [Terms](https://redseacreatures.com/terms): reuse terms for text and photographs
