A new species of hammerhead shark named Sphyrna alleni has been discovered in the Caribbean and Southwest Atlantic. Scientists identified it after observing differences in its head shape, vertebrae count, and genetic traits compared to the bonnethead shark. This new species is also known for its unique omnivorous diet that includes seagrass. Due to their small size and vulnerability, Sphyrna alleni may face threats like being caught as bycatch. Protecting this species is important for maintaining biodiversity in the oceans and supporting local fishing economies.
