On The Shoulders Of Giants - Film and Storytelling | Seed&Spark GIANTS is the journey of two young biologists trying to save one of the planet's largest sharks. It’s a story of exploration in the face of the great unknown. It’s a meditation on empowerment, Irish history, and why scientific investigation is so vital to our planet in these challenging times.

Please support On the Shoulders of Giants. Scott DeGraw (producer of the Alien & Ninja Sharks series) has demonstrated his commitment to producing inclusive, conservation-forward shark programming. Basking sharks are long overdue for their turn in the spotlight.

Schematic of how we measured live clingfish suction performance in a water tunnel with pressure transducers

In @fishguy.bsky.social’s lab we have done many studies on the suction cups of dead clingfish. In this new paper, @fishyologist.bsky.social et al and I found that clingfish can control their suction and stick harder than dead ones! @sicbjournals.bsky.social 🐟 🧪

Every fish that we catch has a story, some are crazier than others. We caught this unicornfish during a night dive in Okinawa last year. The trip was memorable because we had to end the dive early when North Korea fired a missile in our general direction and we had to take cover

An integrative taxonomy investigation unravels a cryptic species of Mobula Rafinesque, 1810 (Mobulidae, Myliobatiformes), from the Atlantic Ocean - Environmental Biology of Fishes Manta and devil rays comprise a vulnerable animal group with a complex nomenclatural history and a somewhat unresolved taxonomy. The existence of a putative undescribed species of manta ray in the Atl...

𝑀𝑜𝑏𝑢𝑙𝑎 𝑦𝑎𝑟𝑎, a new cryptic species of Manta Ray, is described from the Western Atlantic Ocean. The existence of an undescribed manta ray species has been suggested for over 15 years and is now formally described. 🐟🧪

Devonian ray-finned fishes were not particularly species rich, particularly compared to their lobe-finned cousins. This implies early actinopts might've also been anatomically monotonous. But a deep dive into their jaw anatomy w/ µCT reveals subtle but important structural diversity.

Here's Why You Should Care About Sharks Many sharks are apex predators, but they aren’t the fearsome threat often depicted. A marine researcher shares his favorite shark facts.

Here's Why You Should Care About Sharks| In honor of Shark Week, here’s my NPR Science Friday interview

I have no idea what the function of the dentiles is in these fish.

Freshly-preserved specimen of Denticeps clupeoides (SAIAB 748770 from Benin), 42.1 mm S.L. Photo by R. Bills.

Denticeps clupeoides is truly a unique fish and the last surviving member of a very ancient lineage of clupeiforms that diverged from the clupeoids during the Mesozoic era. Below is an example of one with life colors that I and others collected in Benin years ago.

Done.
