“…Exceptions were Acestrorhynchus falcatus and A. microlepis, Charax pauciradiatus, Poptella brevispina, and Phenacogaster megalostictus in which the anal fin preceded the dorsal fin as observed in H. macrolepis. The same pattern was described by Taguti et al (2009) in Pyrrhulina australis. Among these species, C. pauciradiatus, P. megalostictus, and H. macrolepis were already classified in the same subfamily based on the long anal fin (e.g., Géry, 1977), a feature that might be related to the early shift of the onset of the anal-fin development.…”

Fishes in early developmental stages frequently have morphological features that differ from those of adult stages, and many characters found later in ontogeny are not available in initial stages. Hence, morphological descriptions of early stages are useful to provide information for the identification of eggs and larvae, a knowledge still restricted among Neotropical fishes. We studied the development of Heterocharax macrolepis, a heterocharacine whose adult specimens from the aquarium trade were kept and spawned at around 23-24ºC. A developmental series of 51 specimens was preserved, ranging from 3.2 mm notochord length to 18.6 mm standard length, covering approximately the first 73 days post-hatching. We described the development of main morphological features emphasizing those useful in the identification of H. macrolepis larvae (i.e., appearance of preopercle spine and development of the pseudotympanum). We also compared H. macrolepis with photographs taken of live larval specimens of Gnathocharax steindachneri, recently included in the Heterocharacinae. Both species have a yolk sac with a small rounded projection directed posteroventrally. Although this information is not yet available for all pertinent taxa, the different yolk sac shape in other representatives of the Characiformes may indicate that this peculiar yolk sac represents an additional synapomorphy of the Heterocharacini.Peixes em estágios iniciais de desenvolvimento frequentemente apresentam características morfológicas distintas dos adultos e muitos caracteres presentes em estágios avançados não são disponíveis em estágios iniciais. Assim, descrições morfológicas dos estágios iniciais de desenvolvimento de peixes são úteis por fornecerem subsídios para a identificação de ovos e larvas, um conhecimento ainda escasso entre peixes Neotropicais. Estudamos o desenvolvimento de Heterocharax macrolepis, espécie de Heterocharacinae cujos exemplares adultos provenientes do aquarismo foram mantidos e reproduzidos entre 23-24ºC. Uma série de desenvolvimento de 51 exemplares foi preservada, medindo entre 3,2 mm de comprimento da notocorda e 18,6 mm de comprimento padrão, incluindo os primeiros 73 dias pós-eclosão. Descreveram-se detalhadamente os principais aspectos morfológicos, enfatizando características úteis na identificação de larvas de H. macrolepis (i.e., surgimento do espinho do pré-opérculo, desenvolvimento do pseudotímpano). Comparamos H. macrolepis com fotografias de larvas vivas de Gnathocharax steindachneri, recentemente incluída em Heterocharacinae. Ambas espécies possuem saco vitelínico com pequena projeção arredondada póstero-ventral. Ainda que a informação não esteja disponível para os táxons pertinentes, o distinto formato do saco vitelínico em outras linhagens de Characiformes pode indicar que esta forma do saco vitelínico peculiar represente sinapomorfia adicional de Heterocharacini.

“…[ 23 ] and Taguti et al . [ 24 ] observed similar transformations in external morphology during early development. The present observations also corroborate the Theory of Saltatory Ontogeny [ 25 ], since development alternated through periods of slow and small changes and fast and large changes.…”

External Morphology of Lophiosilurus alexandri Steindachner, 1876 during Early Stages of Development, and Its Implications for the Evolution of Pseudopimelodidae (Siluriformes)

Pseudopimelodidae are Neotropical catfishes characterized by having slightly to strongly depressed body in fully developed specimens. The largest species of the family with 500 mm SL, Lophiosilurus alexandri, experiences impressive changes in body shape during development, becoming extremely depressed when fully developed. Accordingly, Lophiosilurus alexandri is an ideal species to observe the morphological changes during ontogeny, and to seek solid interpretations on the polarity of characters. Specimens of distinct larval periods (yolk sac, flexion and postflexion; n = 186 specimens) and juvenile stages (n = 20) were analyzed. Changes in body shape, position of mouth and eye, morphology of fins and pigmentation were observed during the development of Lophiosilurus. Larvae (5.7–11.2 mm standard length) had pigmentation concentrated on the head and parts of body, eyes small and pigmented, short barbels, and well-developed finfold. Juveniles (15.9–28.1 mm standard length) had body shape similar to adult, with head depressed and bearing bony ridges, large mouth, dorsally-oriented eyes, small barbels and well-developed shoulder bulges (cleithral width). The greatest morphological changes in the development of L. alexandri occurred during the postflexion larval stage. Relative to standard length, measurements of snout length, head depth and body depth are smaller in juveniles than in larvae, but body width is larger. New interpretations on the phylogenetic characters related to these changes are provided in view of the two alternative hypotheses of the evolution of Pseudopimelodidae.

“…In larvae of Brycon hilarii, total folding of the notochord occurs when individuals reach a TL of 9.00 mm (Oliveira et al, 2012). In larvae of Pyrrhulina australis, notochord folding occurs when the specimens reach a TL of about 5.33 mm (Taguti et al, 2009).…”

“…There were no visible myometers during the postflexion larval stage. The number of myometers differentiates A. lacustris from other species of the Characidae family, such as Pyrrhulina australis (Taguti et al, 2009), Brycon orbignyanus (Faustino et al, 2011), and Brycon hilarii (Oliveira et al, 2012).…”

Ontogenetic development of the tetra Astyanax lacustris was studied under laboratory conditions. Larvae obtained by induced reproduction were maintained individually in tissue-culture plates, at 25°C. Daily observations and morphometric measurements were performed. Larvae hatched with a total length (TL) of 3.02 ± 0.34 mm (average ± standard deviation) without pigmentation and 0.06 ± 0.02 mm³ of yolk reserves. The yolk-sac larval period lasted 26 h post-hatching (hph). During this period, eye pigmentation started, the digestive tract emerged, the anus opened, and the animals began to show steady movements. Inflation of the swimming bladder initiates the preflexion stage, which extended until 230 hph. During this stage, the transition from endogenous to exogenous feeding was observed, with the yolk reserve being completely absorbed after 74 hph (TL: 4.17 ± 0.36 mm). Up to 86 hph it was possible to observe the first food ingested within the digestive tract. This period was followed by the flexion stage, with the folding of the notochord tip and development of the caudal fin (11-13 days post-hatching). Finally, during the last larval developmental stage (postflexion), the segmentation of the fin rays was completed, and the emergence of scales was observed (TL: 5.97 ± 0.65 mm). The larval ontogenetic development of A. lacustris was completed after 22 post-hatching days (dph).
