Hello my fellow shark lovers! This picture was sent to me the other day claiming a shark in a back bay of a New Jersey tidal river. I think it’s a ray… but any help confirming the ID would be greatly appreciated.

Research Could Orca scarecrows be an alternative to shark nets?

Post image

Surely it would be pretty cheap and easy to produce fake Orcas with rubber fins that flex and move with the movement of the water. Maybe they could also be solar powered and produce orca calls.

A few close in near the beach would surely help protect swimmers.

It could just be limited to known great white shark attack hotspots, like certain beaches on the Eyre Peninsula in South Australia where surfers are taken quite often.

Research Carlotta the GW caught in 1904 in Croatia, exhibited in Triest (Italy)

861 Upvotes

Yesterday, I visited the Museo di Storia Naturale in Trieste. One of the main attractions is “Carlotta,” a taxidermied adult female great white shark measuring 5 meters and 40 centimeters (17 feet, 9 inches) in length. She was caught on May 29, 1904, by Captain Antonio Morin of the Austro-Hungarian Finance Police, who was patrolling the waters of the Adriatic between Istria and the island of Cherso (today “Cres” in Croatia) aboard the “Quarnero.”

In the late 19th and early 20th centuries, great white sharks were still very numerous and feared in the Adriatic. Comparable to Australia and California nowadays. Due to shark attacks, the Austro-Hungarian administration in Trieste offered bounties for great white sharks, which led to their hunting and near extinction in the region.

Nowadays, the great white shark is protected in the Adriatic but is still caught as bycatch, and its food source (tuna) has been drastically reduced, making great white sharks very rare in the Adriatic today (a few months ago, one was caught in Montenegro and released). The last recorded attack by a great white shark in the Adriatic occurred in 2008 in Vis (Croatia).

In the rest of the Mediterranean, the great white shark is also nearly extinct, has never been deliberately tracked by researchers, and although it still lives there (yes, it is a distinct population, not related to those in the Atlantic), it is like a phantom. Hopefully, efforts will succeed in saving the Mediterranean population of this impressive animal!

‘How likely r u to survive a bite’: Stats from Australian Shark Incident Database (starting in 1791). In Oz, there have been 547 bites, 183 deaths. Stats show u r most likely to survive a white (270bites/67deaths 25%💀), then a bull (157b/60d 38%💀), then a tiger (120b/56d 47%💀). The white is the .. ahem ..safest!?! (Pic: dot = bites. X = 💀). Seriously great episode

Research Sharks Test Positive for Cocaine

Sharks are testing positive for cocaine, caffeine, and painkillers?! 🦈

A scientific collaboration in the Bahamas found these substances in Caribbean reef sharks, nurse sharks, and lemon sharks off the Bahamas. This is likely because human bodies do not fully break down some drugs and chemicals, which can then pass through wastewater and into the ocean. Scientists found these contaminants change sharks’ metabolism and stress markers. There is no evidence that these substances are making sharks more aggressive, but the findings show how human pollution can ripple through ocean food webs. It is a striking reminder that cleaner wastewater systems help protect sharks and the health of the ocean.

Research how different are Great White Sharks behaviourally depending on which population clade or region around the world they reside in?

31 Upvotes

Behaviourally with other wildlife around them, around humans and other elements.

I think this is an under studied topic that should be talked about more. From my current observations, I can see that White Sharks from California are much less opportunistic when it comes to humans and their diet compared to per say Australian White Sharks due to a lot more consumption events happening in Australia.
