NEW RESEARCH - Proud to finally share my first lead-author paper on Whale Shark movements! 🐋🦈 We found sex-specific differences that improve our understanding about movements by females 🌏🔭 Link to read https://t.co/75PIYBJhBZ @CSIRO @UTAS_ #NingalooOutlook

There was some evidence that females preferred cooler waters than males, particularly in Spring months. On average, females also appeared to dive deeper in warmer temperatures (>26°C) relative to males.

[Dr. Neil Hammerschlag @DrNeilHammer]

Following the loss of white sharks from False Bay, both seals and sevengill sharks have increased in relative abundance, coinciding with declines in small fish that seals feed on and smaller sharks that sevengills prey upon.

New publication in @SciReports showing the effectiveness of electric deterrents to reduce risk of bites from white, tiger, and bull sharks.

These deterrents have now been tested on the three species responsible for the most fatal bites.

Most incredible science discovery this decade! Changes every textbook. Manganese nodules produce oxygen in the #deepsea!!? ⁦These are the nodules targeted for mining… they make oxygen… 😳🤯⁩ ⁦@DeepSeaPod⁩ ⁦@DSBSoc⁩ ⁦@BBCMorelle⁩ https://t.co/gQHO38D3v4

@WestOzFish Loved working with Desy few years back - he’s a legend, as they all are! Hope the trip goes well!

Stole this vid of an orca predating on a whale shark off of fb 🔗👇

They are displaying v similar behaviour to Port and Starboard, but in the Sea of Cortez. It seems the first orca is distracting the WS while the second removes the liver! Fascinating.

@SharkColin @icft2023 @IMOSAnimalTrack @ShioriSharky @JK_Matley @RobHarcourt @FabriceJaine @HuveneersSSEG Looks like an exciting talk! Is it based on a new paper or synthesising previous findings?

How I spent #worldoceansday - out on the water doing research and getting visited by some v cool marine life!! This dive was the highlight of many ocean experiences over the past 10 days at #Ningaloo 🐟 @WorldOceansDay @CSIRO

[Dr. Vincent Raoult @sawsharkman]

There's an official government petition to raise the PhD stipends in Australia to $45k. Their current rate of less than $30k makes it impossible to focus on research and will have long term impacts on Australian trained scientists. Sign it! https://t.co/vX64i8ErM1
