Researchers of the EU-funded?EcoScope project?based at the?Oceanographic Centre of the Baleares?(IEO-CSIC), the?Oceanographic Centre of Santander?(IEO-CSIC) and the?University of the Balearic Islands?at Palma, tagged 3,738 fish belonging to 23 different shark and batoid species caught in surveys over more than two years starting in June 2021. Their study, titled “Elasmobranch Mark–Recapture Experiment off the Balearic Islands: Insight into Scyliorhinus canicula Growth, Mobility, and Population Size” and published in the scientific journal?Fishes?in August 2024, found “striking differences in population size estimations”, suggesting that MEDITS population density estimates for the shark species S. canicula are likely overestimated, presumably due to its scavenger behaviour leading to them being overcounted near fisheries where discarded fish attract them. The research was co-authored by Francesca Ferragut Perelló, Paula Sánchez-Zulueta, Sergio Ramírez-Amaro, Maria Teresa Farriols, Noemi Pasini, Beatriz Guijarro, Cristina Rodríguez-Cabello and Francesc Ordines. ?? ?? ?? ?? https://lnkd.in/dDfRBzXn #EU #EcoScope #Marine #Research #Shark #Species #Monitoring #Fishes #Balearic #Islands Universitat de les Illes Balears?Instituto Espa?ol de Oceanografía

Scientists have found a fanged fish that looks like an alien Scientists from the Commonwealth Research Organization (SCIRO) have discovered a new species of fish while exploring undersea volcanoes off the coast of Australia. The find looks like an alien from a horror movie - it has no scales at all, but it has powerful fangs. The discovered fish looks like the stuff of nightmares, but is just over an inch (2 and a half centimeters) long. This way it would easily fit on the tip of your finger. The black fish weren't the only strange discovery scientists discovered eddies in the ocean that were home to lobster larvae, eel-like mothfish, and bristly-toothed butterflyfish (which, by the way, also boast sharp teeth). According to marine scientist Ian Suthers, the discovery showed that lobster larvae are capable of growing far out to sea. Previously, we thought that lobsters grew in coastal estuaries, and when the larvae were carried out to the open sea, they died. But it turns out that they can also live in ocean vortices. This is a very important discovery for the country's fisheries, Suthers said. Thus, the recently discovered ancient underwater volcanoes boast a diversity of life.

Should you pick up a sea star? Exploring beach tidal pools can be an enchanting experience, particularly when searching for unique marine species like the Sea star or Starfish. These marine invertebrates, known for their distinctive central disc and typically five arms, play a crucial role as keystone species within marine communities. Their diverse diets and adaptability make them ecologically significant (Villier, 2013). While the allure of interacting with nature is strong, it's essential to exercise caution. Starfish can only breathe underwater, with most species unable to survive out of water for more than 3 to 5 minutes. Some species can't even last more than 30 seconds when exposed to open air (Here et al., 2020). To learn more about the pentameral symmetry of starfish, check out Wu et al.'s research on ArXiv (2012). For additional insights on the biology and ecology of Asteroidea, Villier's study in Marine Biology Research (2013) provides valuable information. Remember, when admiring these fascinating creatures, it's best to observe with our eyes, not our hands, to ensure the safety of both ourselves and the starfish.

All #marinemammals produce #sounds #underwater to #navigate, #hunt, and #communicate with each other, and #scientists can listen to these sounds to learn more about them. The #Passive #Acoustic #Ecology Program at the Southeast #Fisheries #Science Center uses underwater recording instruments to listen to, record, and detect all types of sounds in the #ocean, including the sounds produced by #whales and #dolphins (cetaceans). These recordings and detections of #vocalizing #cetaceans help us to understand their distribution, abundance, habitat use, seasonal and longer term movement patterns, and calling behavior. All of this information contributes to management and #conservation efforts. They conduct large-scale short-term #surveys using towed acoustic instruments during our?ship-based offshore population assessments. They also conduct stationary long-term surveys using moored instruments that remain on the #seafloor for long periods of time. These #passiveacoustic surveys are complementary to our visual surveys. They improve our ability to assess the population status of many #marinemammal #species inhabiting the Gulf of Mexico, the southeast U.S. waters of the North Atlantic, and the Caribbean. #mai #marineacoustics NOAA: National Oceanic & Atmospheric Administration NOAA Fisheries NOAA National Ocean Service #NOAA #sonar #mammals #innovation #research https://lnkd.in/epWWbrHa

https://lnkd.in/gTHb5Wt2 ? Article title: A ‘Field of Mouths’: Damselfishes in the Intertidal of Heron Island Cay, Great Barrier Reef ? Author(s): John Lucas*, Leya Koh, Maximilian Rath, Jasper Synowski, Richard Vierick and Salomé Willer ? Journal: Annals of Marine Science ? Journal ISSN: 2640-2300 ? Abstract: The study was undertaken in the intertidal zone on the lee side of Heron Island cay (southern Great Barrier Reef) where there is a high density of branching corals. We investigated the influence of coral colony size on the diversity of damselfish species (Pomacentridae) associated with the branching corals. Forty coral colonies were marked and the associated pomacentrids photographed and identified. Eleven or twelve species were identified and there were up to eight species associated with a coral colony. The relationships between diversity of fish species and coral colony area, and coral colony perimeter were very significant. Plankton samples in the vicinity of the fringing reef are sparse during the day when the fish are feeding compared to the rich samples at night when they aren’t feeding, suggesting a substantial impact on the zooplankton content of the water flowing over the fishes’ habitats. In contrast to the ‘wall of mouths’ on the windward crest of a patch reef, it is suggested that these pomacentrid inhabitants of the shallow waters fringing Heron Island cay constitute a ‘field of mouths’. During the day, they trap and retain the allochthinous organic material that flows across the shallow coral reef and act as a source of nutrients for this coral reef ecosystem. ? #Damselfishes #Pomacentridae #Planktivores #Fish diversity #Heron Island cay #Branching coral #Great Barrier Reef ? #FisheriesScience #FishingTechnology #FisheriesManagement #EnvironmentalFisheries #FishHealth #FishCulture #Oceanography #Ecology #FishPhysiology #EvolutionaryResearch #PopulationDynamics #EcosystemAnalysis #FisheriesEconomics #MarineBiology #MarineBiodiversity #MarineGenomics #MarineEcology #MarineResources #MarineChemistry #MarineEnvironment #MarineBiotechnology #BiologicalOceanography #ChemicalOceanography #GeologicalOceanography #PhysicalOceanography #OceanEngineering

?? How much do you know about Dodo birds? ? Turns out it may be less than you think! ?? A team of researchers from the University of Southampton, the Natural History Museum, and the Oxford University Museum conducted a comprehensive review of the taxonomy of the Dodo and its relative, the Rodriguez Island Solitaire. ?? They revisited 400 years of scientific literature and physical collections, challenging many long-held misconceptions, including the existence of the mythical Nazarene Dodo and the White Solitaire. ?? Much of the early knowledge about the Dodo was based on incomplete remains and inaccurate sailor accounts, leading to the bird being considered a mythological creature during the 18th and 19th centuries. ??♂? Contrary to its popular image as a slow and clumsy bird, evidence suggests the Dodo was actually a fast-moving and active species, well-adapted to its environment before human interference. ??? The researchers also confirmed that both the Dodo and Solitaire belonged to the columbid family, which includes pigeons and doves, dispelling the belief that multiple species of these birds existed. ?? Their extinction marked the loss of a unique branch of the pigeon family tree, and a better understanding of their role in the ecosystem could contribute to ongoing recovery efforts in Mauritius. ??

#Chlaenius #nitidulus, known as the Shoreline #Ground #Beetle, is a member of the ground beetle family (Carabidae) with a body length of up to 12.5 mm. It boasts a metallic green head and copper-green pronotum. The lateral edges of the pronotum taper towards the rear; the rear angles are not rounded. The elytra are intensely green with a delicate fuzz. The legs are yellow, with the thighs being more orange. Antennal segments 1-3 are bright, yellow-orange, while the remaining segments are distinctly darker. ? The Shoreline Ground Beetle is a European species, with a range that spans from the Pyrenees and Basque Country in the west, to the European part of Russia in the east, and from the southern coasts of Great Britain, Sweden, and Finland in the north. It is also found on the Faroe Islands. To the south, its range extends to the northern coast of the Mediterranean Sea up to the European part of Turkey, but it is not present in G Screenshot has been saved to/Pictures/Screenshot encountered up to an altitude of 600 meters above sea level. Chlaenius nitidulus thrives in moist areas such as the edges of marshlands, lakes, rivers, and wetlands. It favors clayey and loamy soils with heterogeneous vegetation, for example, grassy banks of nutrient-rich waters or coastal floodplains. It is also found in cultivated fields and home gardens. The Shoreline Ground Beetle feeds on small invertebrates, such as insects and their larvae, snails, and earthworms. In Europe, including Poland, the presence of Chlaenius nitidulus is not considered endangered and does not fall under species protection. #Insect #Beetle #Chlaenius #Chlaeniusnitidulus #Entomology #Shoreline GroundBeetle #GroundBeetle #Carabidae #Biodiversity #Conservation #Nature #Insects #Ecosystem #Wildlife #Europe #Species #Habitat #Ecology #Environment #Science #Biology #Zoology #Fieldwork #Natural History #Research #Sustainability #Education

These sharks found off the coast of Southern California look completely different, but have something in common — they all exhibit rare skin color patterns! But what are these patterns, and how rare are they? A recent study led by Scripps Oceanography alum Zach Skelton describes these uncommon markings observed in four shark species. "Our study included a horn shark and tope shark that lacked pigment across only part of their body, called leucism, and a swell shark that completely lacked body pigment, called albinism," said Skelton (MS in marine biology, '20), a biologist for Ocean Associates, Inc. and contractor at National Oceanic and Atmospheric Administration (NOAA) Southwest Fisheries Science Center. "In addition, we redescribe an unusual color pattern of leopard sharks from several individuals in the wild and captivity." Using photos gathered from the researchers and citizen scientists documenting these rare color aberrations, researchers combed the literature to understand these specific conditions. Leucism and albinism collectively fall under the umbrella of hypomelanosis, which is a very rare birth defect that causes unusual patches of light-colored skin. These cases have only been observed in 69 species which represents less than 5% of all sharks, rays, and related species. Due to their rarity, most sharks with these conditions are only identified by pictures alone, and only 1 of the 84 previous studies obtained and analyzed skin samples. "This research is important because the rarity of individuals with such conditions means they are often encountered by chance and therefore little is known about them," Skelton said. "These sightings help researchers understand the biological significance of these color patterns to help inform future observations.” ?? Dive into the study: https://bit.ly/4aPq08W
