🚨 New paper alert! 👀In our new opinion piece in @Trends_Ecol_Evo, we propose #cephalopods as model systems to investigate the link between tactical #deception and #cognition in animals 🐙🦑🪄✨🧠 Read the paper here: 🔗 https://t.co/OEhMYthHPz

Moreover, we find that when controlling for underlying abundance, #lionfish are encountered deeper, form larger maximum #group sizes and are caught in larger maximum catch sizes in areas with higher #hunting pressure. @Sam_Matchette @MarineBehavEcol @JHerbertread

🚨Our new paper is out now in Biological Invasions. Using a #citizenscience approach we find correlations between #invasive #lionfish abundance, the length of time invaded, and human #hunting pressure in the western #Atlantic and #Caribbean Sea.

🚨 Our new paper is out now in Ethology. Here we show that #lionfish show social attraction to conspecifics when selecting shelters.

Group formation in animals can arise from two primary mechanisms: individuals aggregating over resources, or individuals socially benefiting from interacting with conspecifics. Distinguishing...

Overall, we find no evidence that lionfish utilise ambient soundscapes of different habitat types for directional orientation during the day.

Moreover, lionfish activity was not influenced by the habitat playback type, nor did their preference interact with body size.

When exposed to sandy or reef habitat playbacks versus a silent control, lionfish displayed no preference to associate with either soundscape, nor did they choose to associate more with either habitat soundscape when broadcast simultaneously.

🚨Excited that the first chapter from my PhD is now out in Marine Biology. Here we show that #lionfish do not show any directional preferences for ambient #soundscapes during diurnal hours. 🔗 https://t.co/6P43HIRsNv 🧵A thread to find out more:

Marine Biology - Sound is a valuable cue in the marine environment that can inform animals about habitat location and community composition. Indeed, sound is often used for orientation and...

Thrilled to be featured in #Forbes - I'm over the moon that our research is reaching so many interested people 🎺🐠
Scientists have discovered an unusual way trumpetfish stalk their prey by using other fish to disguise their deadly movements. https://t.co/UpV53DLxBa

🚨 We are delighted to announce that our new paper is out TODAY in @CurrentBiology 🚨 Here we provide the first direct evidence of how a predator - the trumpetfish - can use ANOTHER ANIMAL for concealment when hunting! 🔗 https://t.co/9vaKLh0Wdw 🧵 Thread to find out more: (1/7)
