First record of albinism in the rockfish Sebastes pachycephalus complex (Scorpaeniformes: Scorpaenidae)

Partial albinism in the Revillagigedo sea chub Kyphosus sectatrix (Perciformes: Kyphosidae) from Clarion Island, Mexico

“…2b). Abnormal color in this specimen coincides with description of teleost fishes with abnormal coloration (e.g., Kwun et al, 2016;Mansur, 2011;Muto et al, 2013Muto et al, , 2016 related to a dysfunctional melanin pigmentary system known as partial albinism. For the first time, we report this abnormal body coloration in K. sectatrix specimens in Mexican Pacific waters.…”

“…Anomalous body coloration in fishes usually occurs either as a deficiency of pigmentation known as "albinism" or as an excess called "hypomelanosis" or "melanism" (Jawad et al, 2013;Simon et al, 2009); whereas a particular form of albinism called xanthism is phenotypically expressed as a bright yellow or orange body coloration (e.g., Amaoka, 1995;Carson, 2011;Lewand et al, 2013). Albinism ocurrs in 2 forms: i) complete albinism, where the integumentary and retinal pigmentation is absent and ii) partial albinism or leucism, where there is a partial or complete loss of integumentary pigments, but the retinal pigments are present (Bottaro et al, 2008;Muto et al, 2013;Sandoval-Castillo et al, 2006;Reum et al, 2008). The present note reports the occurrence of partial albinism in an individual of the Revillagigedo sea chub K. sectatrix observed at Clarion Island, Revillagigedo Archipelago, Mexico.…”

First record of abnormal body coloration in a rockfish Sebastes trivittatus (Scorpaenoidei: Sebastidae)

“…However, most of these were considered to have been caused by skin tumors, resulting in black patches on the body, with other color abnormalities having been relatively rarely documented [Love et al 2002; but see Muto et al (2013) for partial albinism; Lewand et al (2013) for xanthochroism].…”

First record of albinism in the brown sea cucumber Isostichopus fuscus in the Gulf of California, Mexico

“…There are two kinds of albinism: complete albinism is the total absence of integumentary pigmentation, and partial albinism or leucism is the partial or complete loss of integumentary pigments but with retinal pigments present (Goto et al, 2004). This phenomenon has been reported in mammals, reptiles, fish, sharks and invertebrates (Fertl et al, 2004;Sandoval-Castillo et al, 2006;Modesti et al, 2011;Zhao et al, 2012;Muto et al, 2013). This mutation is also present in the Holothuroidea class; nevertheless, information about the occurrence of albinism in these kinds of echinoderms is scarce and refers to species from temperate to cold regions of the ocean (Casellato et al, 2006).…”
