The HideShark dataset

Every guide, added up

HideShark tracks structured facts — taxonomic group, conservation status, diet, habitat — behind every one of its 4,048 hand-written animal guides. This page turns that into an at-a-glance dashboard, and the bottom of the page has a free CSV/JSON download of the whole dataset if you want to explore it yourself in Excel, Python, or SQL.

Species by group

Every animal belongs to exactly one group, so these percentages sum to 100%.

Invertebrates 690 · 17%

Conservation status

IUCN-style status, ordered from least to most at risk. Every animal has exactly one status, so these also sum to 100%.

Least Concern 2,617 · 65%

Near Threatened 236 · 6%

Vulnerable 306 · 8%

Endangered 219 · 5%

Critically Endangered 154 · 4%

Extinct in the Wild 4 · 0%

Extinct 11 · 0%

Data Deficient 35 · 1%

Not Evaluated 466 · 12%

Diet

Animals can have more than one diet (an omnivore that's also a scavenger, say), so these add up to more than 100%.

Carnivore 1,775 · 44%

Omnivore 885 · 22%

Insectivore 819 · 20%

Herbivore 704 · 17%

Filter feeder 107 · 3%

Habitat

Also multi-value — many animals live across more than one habitat type — so these add up to more than 100% too.

Temperate forest 1,452 · 36%

Temperate grassland 1,170 · 29%

Rivers & wetlands 1,163 · 29%

Coasts & shorelines 789 · 19%

Savanna & grassland 181 · 4%

Polar & tundra 103 · 3%

Which groups carry the most conservation risk?

"Threatened" here means the standard IUCN bucket of Vulnerable, Endangered, or Critically Endangered. Grey segments are Least Concern; amber covers Near Threatened, Data Deficient, and Not Evaluated (a data gap, not necessarily good news); red is the threatened bucket above plus any Extinct or Extinct-in-the-Wild guides.

Mammals 30% threatened

Amphibians 23% threatened

Reptiles 19% threatened

Fish 14% threatened

4,048 rows, last generated November 8, 2026. The CSV and JSON aren't byte-for-byte identical in shape — CSV can't hold real arrays, so multi-value fields are joined with a semicolon; the JSON keeps them as arrays and is a plain top-level list of records (so pandas.read_json(url) loads it directly, no unwrapping needed).
