FIGURE 2 | Ontogenetic development of the lateral-line canals in larvae and juveniles of Electrophorus varii, in lateral and dorsal views. A. 1.9 cm TL; B. 2.5 cm TL; C. 3.0 cm TL; D. 5.0 cm TL; E. 9.0 cm TL; F. 38 cm TL. Types of dashes indicate the (1) shallow and short grooves on the skin; (2) deep grooves; (3) segments of grooves start enclosure; (4) pores of canals on the skin. Yellow: infraorbital canal; navy blue: mandibular canal; green: otic canal; purple: pre-opercular canal; pink: supraorbital canal; light blue: supratemporal canal; grey: posterior lateral-line canal of the trunk and; red: otic pit between cephalic and trunk canals. Arrows indicate short grooves of the presumptive infraorbital and mandibular canals. ... : Published as part of Verçoza, Gabriel, Shibuya, Akemi, Bastos, Douglas A., Zuanon, Jansen & Rapp Py-Daniel, Lúcia H., 2021, Organization of the cephalic lateral-line canals in Electrophorus varii de Santana, Wosiacki, Crampton, Sabaj, Dillman, Mendes-Júnior & Castro e Castro, 2019 (Gymnotiformes: Gymnotidae), pp. 1-16 in Neotropical Ichthyology (e200075) 19 (2) on page 6, DOI: 10.1590/1982-0224-2020-0075, http://zenodo.org/record/13321959 ...
