(Linnaeus, 1766)

Conservationis status

LC

Vigens (IUCN 3.1)^[1]

Electrophorus electricus (aliis speciebus propositis^[2]), in variis linguis anguilla electrica vulgo appellatus, est piscis electricus ordinis Gymnotiformium, qui piscis in America Australi invenitur. Usque ad annum 2019, classificabatur sola sui generis species.^[2]

Anatomia[recensere | fontem recensere]

Electrophoro electrico est corpus praelongum et cylindricum, quod plerumque ad 2 metra longum crescit, 20 chiliogrammatibus ponderis, ut maxima ordinis species sit.^[3] Colores sunt fuscus obscurus in tergo et flavus vel aurantius in ventre. Colores feminarum maturarum in abdomine obscuriores sunt. Eis non sunt squamata. Os est rectangularis, prope finem rostri situm. Pinna analis secundum corpus totum ad apicem caudae extenditur.

Ut in aliis ostariophysorum piscibus, vesica natandi in duo conclavia finditur: conclave anterius cum auri interiori serie parvorum ossium ex vertebris colli evolutorum (apparatus Weberianus appellata) conectitur, facultatem audiendi amplificans; conclave posterius secundum totum corpus extenditur, et levitati piscis moderatur.

*Electrophorus electricus* in Aquario Novae Angliae.

Systema respiratorium est vascularizatum, ubi commutatio gasium per textum epitheliale in lacuna buccali fit.^[4] Electrophori electrici, quia aerem spirant, ad superficiem decimo fere quibusque minutis surgere ad spiritum ducendum debent, antequem iterum ad imam aquam redeunt. Ei paene octoginta centesimas eorum oxygenii sic adipiscuntur.^[5]

Contra nomen vulgare, Electrophorus electricus ad anguilliformes veras non arte conectitur, sed est socius Gymnotiformium neotropicorum, qui ad siluriformes artius conectitur.
