The crown-of-thorns starfish, Acanthaster planci, is a major coral predator widely distributed in the Indo-Pacific region, where population outbreaks have caused dramatic impacts on reefs. In Tropical Eastern Pacific (TEP) A. planci occurs at low densities; it has been significantly abundant only Panama and Cocos Island. We recently found two individuals of Malpelo Island, small oceanic island with significant communities located off Colombian coast. recent discovery light reports its...
A variety of abnormalities have been described for sharks, rays and skates across different ecoregions. Morphological functional anomalies in these species, however, were not yet documented distributions from the Canary Islands, spiny butterfly ray Gymnura altavela (Linnaeus, 1758) situ observations. The aim present study is to fill knowledge gaps. female G. with an unfused anterior part right pectoral fin neurocranium was observed port Sardina del Norte (Gran Canaria Island) during a visual...
The ecotouristic approach to sharks and rays has developed rapidly in the last 20 years. We studied three species Gorgona Island from 427 dives ( 2004-2011), including 866 photographs videos. There was at least one sighting 34.4% of dives, 25.0% photos videos were useful for identification individuals. T. obesus seen all months year, its presence correlated with depths 20-30m (66.9%), sandy-rocky bottoms (79.8%), western (61.2%) south (52.9%) areas island. southern area had groups up 9...
<title>Abstract</title> The paternity patterns observed in decapods reflect the mating strategies and tactics employed by different species. However, these may be altered fishery management, particularly through male-biased harvesting, which affects natural sex ratio subsequently influences success reproductive success. This study examined of kelp crab Taliepus dentatus, revealing that, unlike other majid crabs, T. dentatus demonstrates a single pattern, apparently unaffected fishing...
Here, we describe the first mitochondrial genome of angelshark, Squatina squatina. The is 16,689 bp in length with 13 protein-coding genes, 22 tRNA 2 rRNA and a non-coding control region. Base composition mitogenome has an A + T bias (62.9%), seen commonly other elasmobranchs. This provides key resource for future investigations population genetic dynamics evolution this Critically Endangered shark.
The present communication documents the first observation of a morphologic anomaly in juvenile Spiny Butterfly Ray Gymnura altavela. This is interesting for its similarity with rostral abnormality an adult G. altavela from Canary Islands 10 years earlier and one Long-tailed poecilura Western Indo-Pacific. Although no firm conclusions can be drawn these records, it reinforces hypothesis congenital disorder this type malformation within genus. individual appeared to have successfully adapted...
