1/8 For years, it’s been assumed that when fishes hover in open water, they’re just resting. Our new @pnas.org paper shows otherwise: hovering can double metabolic costs compared to true rest in near-neutrally buoyant fishes. Here’s what we found: www.pnas.org/doi/10.1073/...

Marine Mammal Acoustics in a Noisy Ocean
This open-access book explores the potential impacts of noise on marine mammal species such as whales, dolphins, seals, seacows, and otters.
New free book: "Marine mammal acoustics in a noisy ocean", looks like an incredible intro to how sound works in the ocean and an overview of some of the big outstanding questions and answers.

Post-ablation, fish swam faster, took more direct paths, and made frequent contact with obstacles, perhaps sensing with snout and fins… or just bumping into things.
Congratulations to Sonia and Fidji Berio (Postdoc in the lab!) for the nice work!!

New publication led by my MS student, Sonia Marketaki:
We tested how blind cavefish navigate a novel 3D obstacle course after lateral line ablation. Despite losing their primary mechanosensory input, the fish altered their behavior to complete the task. 🧪 🐟

Reality check: coral restoration won’t save the world’s reefs
New research examined coral restoration projects worldwide to calculate what it would actually cost to bring back what’s already been lost.

We found that the sharks:
- adjust their body posture and tail movements across speeds 📐
- display higher variation in kinematic patterns at low versus high speeds, suggesting reduced hydrodynamic stability ⚖️
- display a peak in kinematic efficiency at higher speeds than more active shark swimmers ⏩

Fish schools are three-dimensional, with fish constantly rearranging their positions relative to each other. Fish can school in groups in a circular motion with little mean forward velocity or undertake active directional locomotion where the group moves forward along a common mean path as shown (photos via Getty Images).
