Diving deeper for richer prey? - GEOMAR Helmholtz-Zentrum für Ozeanforschung Kiel: METEOR expedition M202 investigates the ecology of prey to better understand hunting behaviour of toothed whales in the Atlantic.

Dytiscidae are commonly known as predaceous diving #beetles, with their #larvae knick-named water tigers due to their insatiable appetite. These #aquatic insects are found in #freshwater habitats worldwide. With elongated bodies and specialised adaptations for life underwater, they prey on small, aquatic organisms including #insect larvae and tadpoles. Have you spotted any interesting insects? #CnRconsulting #aquaticEcology

🌊 Explore the World of extraordinary Blue Spotted Stingrays! The blue spotted stingrays (Neotrygon kuhlii) are among the most fascinating marine creatures… the Andaman Sea around Koh Lanta offers a unique opportunity to learn about them. ➡️ Educational Insights: - Unique Appearance: Their bright blue spots serve as a warning to predators about their venomous spines. - Habitat: Typically found in sandy or muddy areas near coral reefs, using these environments for camouflage. - Diet: They hunt small fish, mollusks, and crustaceans using electroreceptors. - Behavior: Known for their non-aggressive nature, they are often buried in sand during the day. - Ecosystem Role: Crucial in maintaining marine ecosystem balance by controlling prey populations. ➡️ Conservation Note: These stingrays face threats from habitat destruction and overfishing. Sustainable diving practices are essential to protect their habitat and ensure their survival.

Diver Observations on Arctic Charr (Salvelinus alpinus) Spawning Grounds in Llyn Padarn Sites of Special Scientific Interest (SSSI) - December 2010 is #MEDINDataAdvent Day 6 ❄️🎄 Llyn Padarn is a large, natural lake located at the foot of Snowdon alongside the village of Llanberis, North Wales. The lake is designated as a Site of Special Scientific Interest (SSSI) for its rare, genetically distinct Arctic charr (Salvelinus alpinus) population, the presence of the nationally scarce Annex II aquatic macrophyte, Luronium natans L. (Floating Water-plantain) and the exposure of geologically important Cambrian rock sequences. The Arctic charr population is one of only three naturally occurring populations in Wales and one of the southernmost in the UK. There has been concern in relation to the declining Arctic charr population in Llyn Padarn and the potential impact of the water quality of the lake on the population. This study was undertaken to investigate potential spawning areas in the lake for Arctic charr by a SCUBA diving survey. Knowledge of the location of the spawning grounds of charr in Llyn Padarn is important to inform management of the site for conservation of the species. The purpose of this data capture was to collected information so that any additional spawning grounds (to the one location known) could be identified along with any potentially important spawning sites. Data are held with Cyfoeth Naturiol Cymru / Natural Resources Wales https://hubs.la/Q02-5t3H0

Dubbed the ocean's best buddies by Marco himself, these microalgae play a crucial role in forging endosymbiotic bonds with corals, sea anemones, sponges, jellyfish, and more.🪼 Passionate about diving? These dinoflagellates are essential for the stability and vivid pigmentation of coral reefs, creating lively and colorful underwater landscapes.🪸 Yet, the decline of 𝘚𝘺𝘮𝘣𝘪𝘰𝘥𝘪𝘯𝘪𝘶𝘮 populations leads to bleaching, severely impacting reef health. It's a perfect opportunity to reflect on the importance of protecting our oceans.

"Looking for a unique blend of natural beauty and scientific significance? Look no further than Hanauma Bay State Park! As a protected marine sanctuary, this Hawaiian wonder is not only a popular destination for snorkeling and scuba diving, but also a valuable site for marine research and conservation. Let's appreciate the importance of preserving our planet's incredible ecosystems and the amazing creatures that call them home. #HanaumaBay #MarineConservation #Sustainability #HawaiiStateParks #NatureMeetsScience"

Egypt's Red Sea coral reefs are under threat from climate change and human activities, which have led to a decline in live hard coral cover. The reefs are a vital habitat for fish nurseries and a major tourist attraction, earning Egypt an estimated $7 billion per year. However, some pessimistic projections suggest that climate change could eliminate 74% of Egypt's coral reef habitats by 2100. Just sad when that was your childhood. Possibly the last generation that could scuba dive and enjoy looking at beautiful coral reefs.

Costal Manta Rays (aka "Reef Mantas") are one of two manta species that you can see while diving in Hawaii. Coastal Mantas (Mobula alfredi) are found in nearshore waters, usually where there are concentrations of plankton. And, unlike their pelagic cousins, Coastal Mantas appear to have a home range and don't migrate. In other words, each island (e.g., Maui, Oahu, the Big Island) has its own population with no apparent interaction between groups - at least according to tracking data. Individual mantas can be identified and tracked by unique pigment spots, which are especially prominent over the ventral abdomen.
