.Victoria Camilieri-Asch is unlocking the secrets of shark cartilage in deepwater chondrichthyans. Why? When you consider at ~2000m deep the pressure on cartilage is equivalent to that in a human knee after a 5m jump, you can see how biomicry can change our daily lives! #SharksInt2022

New open-access paper! We quantified catch rate, shark sightings and shark depredation at a spearfishing competition in the GBR marine park through citizen science Catch rate was 1.25 fish per hour, 358 sharks were sighted and depredation rate was 5.9% mdpi.com/2079-7737/11/1…

NEW PAPER! 🦈🐟 In this open access review we provide an update on the latest advances in shark depredation research and discuss key principles for management and mitigation of depredation. Thanks to all those involved in this great team effort! link.springer.com/article/10.100…

My first lead author paper was officially published! 🦈 It focuses on quantifying the timing and threshold of thermal migratory cues in juvenile white sharks! 😁 nature.com/articles/s4159…

Pale Blue Dot is a photo of Earth that was taken by the Voyager 1 space probe in 1990 from a distance of about 6 billion kilometers (3.7 billion miles) as it was leaving our solar system. This is what Carl Sagan said about the photo: "Look again at that dot. That's here. That's

Is it possible? One year #migration of a #baskingshark from and back to #Lofoten at 68°N. We were able to recover the tag only 80 km from where we tagged it just over year ago🥳 What a journey! What a team effort!#SharksontheMove #haisommer Havforskningsinstituttet MOVE

Did you know that, like people, great white sharks also have individual preferences for what they eat? Some like fish, some like stingrays, some like dolphins... besjournals.onlinelibrary.wiley.com/doi/full/10.11…

I came across some great #elasmobranch artefacts from the Torres Strait and Pacific Islands at the #BritishMuseum in London. An amazing museum that was well worth the visit!

12 Reasons Why Cities Need More Trees: 1. Temperature Control One large tree is equivalent to 10 air conditioning units, and the shade they provide can reduce street temperature by more than 30%. 2. Noise Reduction Trees can reduce loudness by up to 50%. In urban areas

Great trip to Lord Howe Island to test the efficacy of shark deterrents to reduce depredation led by Jonathan D. Mitchell and Victoria Camilieri-Asch. Definitely enough sharks around for the testings… supported by #SeaWorldFoundation Parks Australia @nswdpi UWA Oceans Institute

Another amazing fieldtrip to Lord Howe Island completed! We tested 🦈 deterrents for fishing and deployed acoustic receivers to track Galapagos sharks.

Shark depredation + bycatch are common at Lord Howe Island. We identified key fisher-shark overlap areas using telemetry and vessel tracking, and collated expert fisher knowledge to aid mitigation efforts link.springer.com/article/10.100…… Australian Marine Parks UWA Oceans Institute IMOS Animal Tracking
