First record of the pacific fanfishpteraclis aesticola (jordan and snyder, 1901) in the tropical eastern pacific

The Pacific coast of Colombia has been poorly explored, and its fauna is one of the least known in the tropical eastern Pacific. Although knowledge of the decapod fauna from this coast has recently increased, the information is scattered in numerous sources. A review of the literature showed that 378 decapods have been reported from this coast, including the islands of Gorgona and Malpelo. The numbers of species are distributed as follows; Dendrobranchiata, 18; Caridea,79; Thalassinidea, 13; Palinura, 6; Anomura, 61; and Brachyura, 201 .Twenty-seven species are known exclusively from the Colombian coast, three of which are endemic to the islands of Malpelo or Gorgona. A list of nominal species is presented, including information on distribution, important references, and synonyms under which the taxa have been reported for this coast. A summary of the history of explorations of the Pacific coast of Colombia as it relates to decapods, is presented. Zoogeographic affinities are briefly discussed for the marine species based on published distributions. Affinities are greatest with the Gulf of California (51.8%), followed by the Galápagos (28.6%), the Indo-Pacific (8.8%), and the Caribbean- Atlantic (7.7%).

We report the occurrence of a major corallivore, the Crown-of-thorns Starfish Acanthaster planci, on the coral reefs of Gorgona Island, Tropical Eastern Pacific. Three individuals were sighted on opposite sides of the island, where they fed on small coral colonies of Pavona varians and Pocillopora damicornis. These sightings are noteworthy in light of reports that have demonstrated that the geographic distribution of A. planci is gradually increasing in the equatorial eastern Pacific, particularly south of the Gulf of Chiriquí (Panama) where it was previously absent.

Squat Lobsters

Seven species of squat lobsters were collected during the TALUD XIV cruise in the Gulf of California, Mexico. Gastrop-tychus perarmatus (Haig, 1968) was collected for the second time since it was described and represents a first record ofthe genus in the tropical eastern Pacific. Its association with gorgonians is also noted from color pictures taken during adeep-water dive in another cruise in the area. Janetogalathea californiensis (Benedict, 1902) was captured in four sam-pling stations, in the same area where it has been previously reported. Three species of Munida Leach, 1820 were collected(M. bapensis Hendrickx, 2000, M. mexicana Benedict, 1902, and M. tenella Benedict, 1902). Records of M. bapensis ofthis cruise combined with additional captures of this species in 2007 in the same area indicate that it is the most abundantdeep-water species of squat lobster in the northern part of the central Gulf of California. Among the species of Munida,M. tenella was second in abundance and included specimens much larger than previously known. The single record forM. mexicana fits within the currently known depth and geographical ranges. Only one species of Munidopsis Whiteaves,1874 (M. depressa Faxon, 1892) was collected, in one of the deeper sampling stations visited during the cruise and itsnorthernmost distribution limit within the Gulf of California is increased by ca two degrees of latitude. The seventh speciescollected during this survey, Pleuroncodes planipes Stimpson, 1860, is a common inhabitant of the California Current and the Gulf of California.

Pomatostegus Schmarda, 1861 is a serpulid genus with three recognized species, mostly from tropical waters. Pomatostegus stellatus (Abildgaard, 1789), was described from the Caribbean Sea, and has been widely recorded in the Pacific and Indian oceans; P. kroyeri Mörch, 1863 was described from Puntarenas, Costa Rica; however, most records from the Tropical Eastern Pacific were referred to P. stellatus. In this work, the two species are redescribed using morphological characters. The main differences are in the shape of the Spirobranchus-type collar chaetae, opercular plate shape and the number of “free” circlets of spines without accompanying of opercular plates. Comments about characters of P. actinoceras Mörch, 1863, described from Philippines, and an identification key for the three species, are included.

The first comprehensive list of 318 coastal fish species recorded from the Islas Marías Archipelago, Mexico, was compiled from recent fieldwork, archival museum collections, and literature references. The jacks (Carangidae, 18 species) and the labrisomid blennies (Labrisomidae, 16) were the most speciose families. Most recorded species occur throughout the tropical eastern Pacific (160 species), while a significant proportion have wider ranges in the eastern Pacific (39), eastern Pacific and Indo-Pacific (39), eastern Pacific and Atlantic (3), or are circumtropical (39) in distribution. Three species occur in the Northeast Pacific, twenty-five are endemic to the Pacific coasts of Mexico, five are endemic to the Gulf of California, and three are endemic to Islas Marías. Cephalopholis panamensis (Epinephelidae), Epinephelus labriformis (Epinephelidae), Mulloidichthys dentatus (Mullidae), Stegastes flavilatus (Pomacentridae), Acanthurus xanthopterus (Acanthuridae), Pseudobalistes naufragium (Tetraodontidae), and Sufflamen verres (Tetraodontidae) were the dominant conspicuous species observed during underwater surveys in 2010. The absence or low abundance of commercially valuable shark, ray, and grouper species throughout the archipelago is discussed.

Unusual Combination

During a recreational fishing trip on May 2017 to Isla Montuosa, Pacific coast of Panama (7.467472, -82.266556; 30 m depth), a specimen belonging to the genus Caranx was captured. The specimen showed an unusual combination of external characters, intermediate among the species known to occur in the Tropical Eastern Pacific (TEP), which caught the attention of the fishermen. A detailed analysis involving traditional morphology and molecular techniques revealed that the specimen corresponds to a hybrid of the species C. melampygus and C. sexfasciatus. This represents, to the best of our knowledge, the first confirmed record of hybridization within the genus and family in the TEP and the second record for the entire Pacific Ocean.

High Diversity

The sea turtle Eretmochelys imbricata inhabits tropical waters of all oceans. IUCN considers this species to be critically endangered and its populations are affected by illegal international shell traffic. We present a pioneer research for Colombia and the Tropical Eastern Pacific, since populations located in 1) Parque Nacional Natural Gorgona, 2) Corales del Rosario y San Bernardo, and 3) Cabo de la Vela (Guajira) were genetically characterized using mtDNA control region sequences. Two new haplotypes for the Eastern Pacific were found, although with low diversity indexes (h: 0.2857 ± 0.1964; π: 0.0009 ± 0.0008). Five haplotypes were found for Corales del Rosario and San Bernardo’s populations, with high diversity indexes (h: 0.9333 ± 0.1217; π: 0.0089 ± 0.0056). Finally, Cabo de la Vela population presented relatively high diversity indexes (h: 0.6429 ± 0.0539; π: 0.0076 ± 0.0041). The genetic distance analysis revealed no significant differentiation between the Colombian Caribbean rookeries (Φst = 0.002, p > 0.05; Fst = 0.083, p > 0.05). However, significant differences were found between Cabo de la Vela nesting rookery and eight nesting rookeries along the Caribbean Sea, which is a genetic pattern characteristic of sea turtles on a global scale. Our phylogeographic analysis revealed a deep split between the Atlantic and the Pacific-Indian Ocean. For Atlantic phylogroup no clear clustering between haplotypes was perceived, while in the Pacific-Indian phylogroup a possible distribution of isolation by distance was observed. The divergence time reported in this study between the Atlantic and Pacific-Indian lineages suggests a separation that may have occurred between the Pliocene and Pleistocene (7 Ma), possibly influenced by the rise of the Panama Isthmus.
