“…Members of the family Labrisomidae correspond to small blennioids, found mostly in the tropics of North America (primarily in Central America) and South America, and comprise 15 genera allocated into five tribes and a growing number of species (Guimaraes et al., ; Baldwin et al., ). Generally staying within shallow coastal regions to depths of around 10 m [except for the genus Haptoclinus , which inhabit deep reefs of 150–160 m depth, off Curaçao, southern Caribbean (Baldwin and Robertson, )], labrisomids are found in a variety of habitats including shallow‐water coral reef crests, reef dropoff areas, patch reefs, rocky tidepools or ledges, algae‐covered rocks surrounded by sand, eroded limestone slopes, turtle‐grass beds, pier pilings, areas with coral rubble and algal mats (Gibran et al., ).…”

Summary The diet, feeding success (prey number and total volume per gut, and maximum prey width) and trophic niche width of the labrisomid blenny Auchenionchus variolosus (Valenciennes, 1836) was studied during its larval development (3.93–17.26 mm standard length). Individuals were collected in October 2012 and October 2013 in nearshore waters (<500 m offshore) from Bahía Valparaíso, central Chile with Bongo nets. When compared to the same length range, larval A. variolosus collected during 2013 showed larger upper jaw‐at‐sizes than those from 2012. This coincided with a reduction in relative importance (%IRI) of the main prey item, copepod nauplii, from ~90 to ~73%. Feeding incidence (FI) was high throughout larval development, varying from 97.3 to 100%, being similar throughout the larval development. Prey items per gut (PIPG) ranged from 0 to 35 prey, showing no differences among years. Total volume per gut (TVPG) was positively correlated with larval length, and at given larval size, TVPG ingested by larval A. variolosus was larger during 2013 (0.0607 mm3) than during 2012 (0.0301 mm3). Prey width range was 47.47–700.94 μm and was positively correlated with standard length (SL). Niche breadth was independent of larval size and did not change during larval development in 2012 or 2013. The study helps to understand the trophic interactions occurring in nearshore waters off rocky reef environments from mid‐latitudes of the Southeast Pacific coasts.

“…The family Labrisomidae is composed by 14 genera distributed into five tribes (Labrisomini, Starksiini, Cryptotremini, Paraclinini, Mnierpini), with 118 known species (Herrera & Lavenberg, 1999; Nelson, 2006) but a growing number of new species (Baldwin et al, 2011; Guimaraes et al, 2010; Sazima et al, 2009). Recently, a monophyletic Labrisomidae was recovered with the exclusion of the Cryptotremini and the inclusion of Stathmonotus (Lin & Hastings, 2013).…”

Parental care and early development of the labrisomid blenny Labrisomus philippii (Labrisomidae) from northern Chile

The parental care of the nests and the embryonic and larval development of the labrisomid blenny Labrisomus philippii (Teleostei: Labrisomidae) were described for the first time. In situ underwater recordings were done on nests deposited at 2‐m depth at Pisagua and Sarmenia, northern Chile. The nests were composed by a mass of adhered eggs, exclusively on red algae covers (Rhodophyta) outside the crevices used by the adult and guarded by the male. Males utilized ~90% of the time taking care of the nest, defending it from predators (other fish and crustaceans), and keeping it clean. For the observation of larvae, egg masses were extracted from the nests and incubated in the laboratory. Eggs are spheroid, 1.09–1.23 mm in size, with filaments originating from a central thallus in the basal pole, small perivitelline space and granular yolk, with numerous small oil droplets. Larvae hatched at an average size of 5.06 ± 0.10 mm body length (BL), with a functional mouth, and a round yolk‐sac of 0.09 mm3. Larvae are elongated, slightly laterally compressed, with a round and moderate head and a short snout. They have preopercular spines and 35 myomeres; melanophores are located on the cleithrum symphysis, over the head, along the base of the anal fin, between pterygiophores of the dorsal ray fin, and in the ventral margin of the gut. During development, larvae grew at 0.28 mm d−1. Finally, this research helped to increase knowledge on early‐life history traits of this coastal fish inhabiting rocky shores along the south Pacific Ocean.
