New paper: Fully protected areas that are large and cover whole reefs provide conservation benefits for reef sharks🦈 Benefits DOUBLE when embedded within areas of effective fisheries management‼️

This 'mixed management' approach boosts global conservation of elasmobranchs🦈

Eagle Rays have specialized dental plates called 'cetotrichia' that they use to crush and eat their prey, which often includes mollusks and crustaceans.

These dental plates are unique to eagle rays among elasmobranchs (the group that includes sharks and rays).

Atlantic Shores: '[we] recognize community concerns surrounding EMF & marine life. Research does indicate that marine organisms, including elasmobranchs (sharks, skates), some fish (eels, sturgeons), sea turtles and benthic invertebrates are electrically sensitive.' #Endangered

🧬🦈🌊 New study reveals the urgency of regulate the trade of sharks and rays in Brazil. A Meta-Analysis of all studies using DNA based methods to track trade of elasmobranchs identified 64 species being commercialized, being 83% threatened ones (IUCN). Check the key highlights:

Happy #fintasticfriday 🦈

Scotland’s inshore seas have some incredible elasmobranchs, such as dogfish, flapper skates, and basking sharks.

On catch #diversity and #historical catch #records of #elasmobranchs (sharks, rays, skates) from a multi-gear fishery in Central West coast of India We recorded 27 species and suggest potential #management measures

World Whale Shark Day 🦈

A day to celebrate the biggest fish in the oceans, these enigmatic elasmobranchs are true gentle giants.

It is always a special feeling when you see those iconic spots appear from the deep. #whaleshark #wildlifephotography

Spotted eagle rays are amongst the most adorably elegant of elasmobranchs (sharks and rays) #spottedeagleray #eagleray #stingray sofcoralcity #stingray #elasmobranch #coral #coral citycamera #miami #portmiami #miami beach #noaa #aoml #coral city #coral cityfoundation

Reposting the giant peacock bass for the #SundayFishSketch theme of best freshwater fish. While I think catfish and river elasmobranchs are still better, the Tucunaré-açú is still high up in my list.

#FactFriday

Did you know that sharks and rays are related?

Both are elasmobranchs, a subclass of fishes that have skeletons made of cartilage.

This ad just popped up on a website I was on and OMFG Whale sharks. Are. Elasmobranchs. Not. Mammals.

Very excited to share that my #MSCA fellowship application for my project FINS (Finding the Identifiable Species in Shagreen) has been successful! With FINS I will study marine #shagreen objects for insights into the #historicalecology and exploitation of #elasmobranchs !🦈

Do you know how crazy a shark-ray is???

and we won’t know until she gives birth.

they’re all elasmobranchs but still

⚠️NEW EPISODE⚠️

This month we're talking about the flattest of the elasmobranchs: the bottom-dwelling batoids - the deep sea rays and skates!

Listen to the new episode with Dr Will White now: bit.ly/3Ukz3Iz

“You can tell how old a shark is by counting the rings on their vertebrae, they also don’t have any actual bones, they’re a type of fish called elasmobranchs, and that means they instead have cartilaginous tissue, they use their gills to-“

A #WorldWetlandsDay 🧵on Oman Gulf #CoralReef fish around Snoopy Island, Fujairah, UAE from Sandy Beach Hotel. 1st Elasmobranchs. In April 2018 young Blacktip Reef Sharks (incl. Striped Remora) common, but in July 2023 rare, like Honeycomb Stingray & Longtailed butterfly ray. 1/25

Great pleasure presenting Important Shark and Ray Areas - ISRAs @ European Elasmobranch Association 2023 #EEA2023 The Shark Trust 🦈🇬🇧

Privelage to share the stage with James Thorburn, Nicholas Dulvy, and Eva Meyers - “Spatial management as a tool for protecting elasmobranchs'.

Random Fact of the Day:
Sharks are elasmobranchs which means they have skeletons made primarily of cartilage rather than bone. Cartilage is a lighter, more flexible tissue and this adaptation helps them be more agile and buoyant in the water.
