This is a GBIF biodiversity occurrence dataset with 610 records spanning 14 columns, covering observations and preserved specimens of organisms across 35 countries, primarily recorded between 2021 and 2026. Despite the filename suggesting carnivorous plants, the dataset actually mixes three distinct taxonomic families — Hesperiidae (skippers/butterflies), Canellaceae (spice plants), and Araceae — each contributing roughly 300, 300, and 10 records respectively, which is a notable data-quality curiosity worth investigating. The dominant species is Canella winterana with 174 records (28.5%), and the US, Mexico, Brazil, and Guadeloupe together account for nearly half of all country-level records. Coordinate uncertainty is severely skewed and problematic: the median is just 35 metres but the max reaches 766,917 metres, with 91 outliers and a 23% null rate, meaning spatial analyses should treat location precision with caution.

This column represents geographic coordinate uncertainty (likely in meters), a standard biodiversity/occurrence record field indicating the spatial precision of a location fix. Two signals are striking: the distribution is extremely right-skewed (skew=17.3, kurtosis=335.7) with a median of just 35m but a max of 766,917m (~767km), and 91 outliers (19.3% of rows) drive a mean of 6,463m versus a median of 35m — suggesting a mix of GPS-precise records and very coarse or placeholder uncertainty values. Additionally, 22.6% of values are null, meaning nearly a quarter of records carry no uncertainty estimate at all.

This column is the GBIF (Global Biodiversity Information Facility) occurrence identifier, a globally unique numeric key assigned to biodiversity occurrence records. With 610 rows, 610 unique values, a null rate of 0.0, and an entropy ratio of essentially 1.0, every record has a distinct ID — perfect identifier behaviour. The top frequency of 0.001639 (1 occurrence each) confirms zero duplication. Values appear to be sequential large integers in the 5937748xxx range, consistent with GBIF's ID scheme.

This column records detailed collection locality descriptions for what appears to be a biological specimen or herbarium dataset, likely from Madagascar (French-language administrative hierarchy: Région, District, Commune, Fokontany) with at least one Brazilian entry ('Serra da Farinha-seca'). The dominant signal is that 92.3% of the 610 rows (563 records) have an empty string, rendering the column nearly uninformative for most records. Among the 29 distinct non-empty values, each of the populated entries appears only 2–3 times, confirming the long-tail alert and suggesting these are free-text verbatim field notes rather than a controlled vocabulary.

This column contains Linnaean binomial scientific names for biological taxa, including both plant species (e.g., 'Canella winterana (L.) Gaertn.') and insect species (e.g., 'Hylephila phyleus (Drury, 1773)'), suggesting a mixed-taxon dataset. The dominant value 'Canella winterana (L.) Gaertn.' accounts for 28.5% of all 610 rows, which is strikingly disproportionate given 157 unique names, and the long-tail alert confirms the remaining mass is spread thinly across many species. Entropy ratio of 0.756 indicates moderate but uneven spread—far from uniform distribution.

This column contains geographic latitude values, ranging from -43.25° (southern hemisphere, around southern South America or South Africa) to 46.70° (northern hemisphere, around central Europe or northern US). The distribution is notably platykurtic (kurtosis -1.28) with a wide IQR of 47.75 degrees, indicating near-uniform spread across a broad swath of the globe rather than clustering around any particular region. The mean (5.20°) and median (17.01°) diverge by ~12 degrees, and the slight negative skew suggests a modest tail toward southern latitudes. With 466 unique values out of 610 rows and zero nulls, this is a real-valued geographic coordinate with moderate but not near-unique cardinality.

This column contains geographic longitude coordinates, with values spanning from -115.04 to 153.39 degrees — a range that covers locations across the Americas, Europe/Africa, and into the Pacific/Oceania region. The mean (-32.94) and median (-63.06) diverge substantially, and the IQR of 120.21 degrees is very wide, indicating the dataset captures globally dispersed locations rather than a single region. A skew of 1.18 suggests a tail toward positive (eastern) longitudes, meaning most records cluster in western longitudes but some pull toward Oceania (e.g., the max of 153.39 is consistent with eastern Australia). With 467 unique values out of 610 rows and zero nulls, coordinates appear mostly distinct but not fully unique, suggesting some location reuse.

This column represents a calendar year dimension spanning 2021–2026, with only 6 distinct values across 610 rows — confirming it is a low-cardinality temporal grouping field rather than a continuous numeric. The distribution is left-skewed (skew = –0.80) with both median and max at 2026, meaning the majority of records are concentrated in the most recent year. The presence of 2026 data (a future or current year at time of writing) alongside 2021 suggests multi-year longitudinal coverage, with recent years — especially 2026 — heavily over-represented.

This column represents calendar month, encoded as an integer from 1 to 12 with exactly 12 unique values and near-zero nulls (0.16%). The distribution is notably right-skewed (skew ≈ 1.0) with a median of 1.0 and Q1 also at 1.0, meaning at least 25% of rows are coded as January — suggesting strong concentration in early months rather than a uniform seasonal spread. The mean of 3.75 versus median of 1.0 confirms this heavy front-loading, which would surprise an analyst expecting roughly uniform monthly representation.

This column is a Darwin Core 'basisOfRecord' field classifying how each biodiversity occurrence was recorded, with only two valid categories present. The distribution is heavily skewed: HUMAN_OBSERVATION dominates at 90.2% (550 of 610 records), while PRESERVED_SPECIMEN accounts for just 9.8% (60 records). The extreme imbalance between field observations and museum/herbarium specimens may affect any model trained on this feature, as PRESERVED_SPECIMEN is a near-minority class. No nulls are present, and the low entropy (0.464) confirms the near-uniform dominance of one category.

This column captures country of origin or location for 610 records, spanning 35 distinct countries with no nulls. The United States dominates at 21.3% (130 records), followed by Mexico (73) and Brazil (51), but the presence of Guadeloupe (48) and Madagascar (40) as top-tier entries is surprising for a dataset this size, suggesting a specific thematic or biological focus (e.g., species occurrences, field surveys) rather than a general population sample. Entropy ratio of 0.77 indicates reasonably broad distribution across countries, though the top-heavy US share introduces mild imbalance.

This column contains biological family-level taxonomic names, with exactly 3 distinct values across 610 non-null rows. Notably, two families — Hesperiidae (butterflies) and Canellaceae (flowering plants) — each appear exactly 300 times, suggesting a deliberately balanced dataset pairing two taxonomic groups, while Araceae (another plant family) appears only 10 times, likely as a minor addition or control group. The near-perfect split between an animal family and a plant family in equal counts is unusual and warrants investigation into dataset construction intent.

This column contains biological genus names, functioning as a taxonomic label for 610 specimens spanning 94 distinct genera. The dominant genus 'Canella' accounts for 28.5% of all rows (174 occurrences), creating notable imbalance — the top four genera alone (Canella, Warburgia, Cinnamosma, Cinnamodendron) appear to be plant genera (order Canellales), while lower-ranked entries like Urbanus, Hylephila, Burnsius, and Pyrgus are butterfly genera (Hesperiidae), suggesting the dataset may mix taxonomic kingdoms or represent a cross-taxon study. Entropy ratio of 0.74 indicates moderate concentration despite 94 unique values.

This column records biological taxonomic names, appearing to be species-level identifiers (binomial nomenclature) though it also contains family-level names such as 'Droseraceae' and 'Sarraceniaceae', indicating inconsistent taxonomic rank across rows. The dominant value 'Canella winterana' accounts for 28.5% of all 610 rows (174 occurrences), which is a striking concentration given 123 unique values and an entropy ratio of 0.74 suggesting moderate-to-high diversity otherwise. The mix of species binomials (plants and insects, e.g. butterflies like 'Hylephila phyleus') alongside family names is a data quality concern that should be flagged before modelling.

This column captures state or province-level geographic designations, with 108 distinct values across 610 rows and no nulls. The top value is 'Texas' (13.3% of rows), but the mix of US states, Mexican states (Nayarit, Sinaloa), Australian states (Queensland), South African provinces (KwaZulu-Natal), Brazilian states (Santa Catarina), and a French Caribbean municipality (Pointe-à-Pitre) confirms this is an international dataset — not US-only. Notably, 30 rows (≈4.9%) contain an empty string rather than a true null, and 11 rows are coded as the catch-all 'Other', both of which will need handling. The high entropy ratio (0.82) reflects genuine geographic spread rather than a dominated distribution.
