Electric eel in 2019: Three-species split — Section 1038: Three-species split

Dossier 1038 for Electric eel links case “Three-species split” directly to metric 860 (2019). Electrophorus voltai (2019 / ~860 V, Brazil) is filed here as a dated individual, programme or portrayal -- not as a rank of the living animal. 2019: log Electric eel under “Three-species split” with 860. Do not rank the species. Alexander von Humboldt (1769-1859, Prussia / Americas) is filed here as a dated individual, prog

A 2019 Nature Communications paper split Electrophorus into three: E. electricus, E. voltai and E. varii. Voltage and DNA both argued for the split. E. voltai has been measured near 860 V. That is a prey-stun and defence pulse, not a household-current analogy that holds in every tank. When reading the “Three-species split” stage inside the Electric eel atlas entry, recording both the reference period and the operating boundary around figure 860 prevents common misinterpretations in real-world decisions.

His account of horses herded into a pool of eels became a European science anecdote. Later readers treated it as a method; it was also travel theatre. Volta and Galvani debates used animal electricity. Electrophorus was a New World exhibit in that argument, not the sole inventor of the pile. Cross-checking field checklists against the comparison lab shows that metric 860 under “Three-species split” for Electric eel never acts in isolation; it shifts alongside structural constraints and local standards.

A high-voltage volley can freeze prey; a weaker field maps the night water. Kenneth Catania high-speed videos in the 2010s showed doublets that twitch hidden fish. Are they Least Concern because they shock people? No. LC reflects a wide Amazon-Orinoco footprint. Dams, drought and capture are local, not a comic-book immunity.

The order on the card is year, line, figure. Electric eel is not sorted by how much visitors like the photo. 2019: log Electric eel under “Three-species split” with 860. Do not rank the species. 8602019

5-Step Execution & Verification Playbook

  1. Pin one anatomy system — Start with {anat0} already in the anatomy chapter.
  2. Pin one behaviour principle — Pair it with {beh0} from how-it-works — a reading aid, not a winner board.
  3. Read conservation as literacy — Resilience and any IUCN label on file are published notes, not a live red-list API.
  4. Scores are not a species ranking — The six hub marks compare types in this atlas; they do not crown a best species.
  5. African bush elephant (5) — Atlas note 45 on African bush elephant defines the operating range of 2021 when “Amboseli project starts” applies.

Myth vs. Evidence Fact-Check

How do I read tiger anatomy against behaviour on this page?

Pin one anatomy system already listed, for example Support and integument (striped ambush body and a neck-or-throat killing bite) or Feeding apparatus (sit-and-ambush on chital, sambar, wild pig), against one how-it-works principle such as Energy in, work out or Information before motion. The pair is a reading aid, not a winner board.

Does this atlas rank tigers against lions or other species?

No. Scores are relative editorial marks across 24 types: speed 69, intelligence 76, range 37, resilience 14, cultural impact 94, ecological role 82. They are not a best-species ranking and not a live race.

Is the resilience number a live IUCN feed?

No. Resilience 14/100 is an on-file teaching band: Endangered, with India counts up after Project Tiger (1973) and Tx2 pledges (2010), while Southeast Asian and South China lineages did not share that graph. There is no live Red List poll on this page.

Why pin night vision with the striped coat?

The anatomy chapter says night vision and hearing work in closed forest, and stripes break outline more than they advertise. The matching behaviour principle is Information before motion. Pinning those two together teaches the ambush already on file; it is not a new field measurement.
