NEW HAMMERHEAD SHARK JUST DROPPED

Not every day does a new shark get discovered! Meet the Shovelbill Shark (Sphyrna alleni), a newly described species of hammerhead shark named after Microsoft co-founder and philanthropist Paul Allen. This new species is found in the coastal waters of the Caribbean and southwest Atlantic.

Hammerhead sharks are easily recognized by their laterally expanded and dorsoventrally compressed heads. Genetic studies have revealed that what was once thought to be a single bonnethead species (Sphyrna tiburo) is actually a complex, with Sphyrna alleni now recognized as a separate species. A longtime advocate for wildlife conservation, Paul Allen and his Paul G. Allen Family Foundation supported Global FinPrint, an international survey of the world’s reef sharks and rays. It was during this project that scientists conducted much of the fieldwork necessary to describe this newly recognized species. The Shovelbill Shark is smaller than the bonnethead, with distinct genetic and morphological characteristics, including a different number of vertebrae, which suggest it is separate from other hammerhead species. This new species is distributed from Belize to Southern Brazil, inhabiting estuaries, coral reefs, sandy and muddy bottom beds, seagrasses, and mangroves.

The Shovelbill Shark is a common component of artisanal fisheries in many Latin American countries and currently lacks proper management or protection. Previous reports indicate that this new species is undergoing overexploitation, making it imperative to safeguard their populations and establish fisheries regulations.

NEW SHARK NEW SHARK NEW SHARK NEW SHARK

EVERYONE SAY HELLO TO THE SHOVELBILL

[fishyfishyfishtimes]

did you hear about the new hammerhead shark species? :o

Only after I got this ask!!!!!

Sphyrna alleni, what a shark!!!! According to the articles it can be distinguished morphologically from the bonnethead thanks to the shape of its cephalofoil and its bigger number of vertebrae. The second article proposes that this species could be called a shovelbill shark as its common name!

This is one magnificent find, no doubt only made possible with a dedicated team of scientists and Belizean fishers! Wonder what other species there are hiding in plain sight that we just haven't been able to find, because they're so similar to other well-known species....

A new species of hammerhead shark related to the bonnethead shark has been discovered!

Sphyrna alleni (also known by its common name 'shovelbill shark') has been confirmed to live in the Caribbean and Southwestern Atlantic.

exciting shark news!!!!!

so scientists discovered a new species of hammerhead sharks called shovelbill sharks also referred to as “Sphyrna Alleni” and it’s all i can think about,,,,,,

like omg, it took them a while to identify the new species because it looks so much like an existing one called the bonnet head shark “Sphyrna Tiburo” and it also lived in a relatively close area to that species as well,, like wow that’s so cool especially cause there’s only 9 species of hammerheads and now there’s 10!!!! :))

wAAAAAA i can’t describe the feeling in experiencing rn other than autistic joy,,,

(there’s a free paper where u can read abt it, right here)

Daily fish fact #866

Sphyrna alleni!

Sphyrna alleni, proposed common name the shovelbill shark, is a recently discovered species of hammerhead shark that was very recently separated from the bonnethead shark! They have a more southern range compared to the bonnethead, their ceohalofoil is more pointy, and they have more vertebrae than the bonnethead.

ooooh i like shovelbill!!! thats fun i hadnt heard about that yet

did you hear about the new hammerhead shark species? :o
