We eat oily fish to get the health benefits of omega-3 fatty acids. However, the level of omega-3s in farmed salmon is changing. How does this stack up to wild-caught salmon? Read more to find out!

Scientists reveal a greasy discovery: swordfish lubricate their heads for speed!

Swordfish boast a variety of adaptations that makes them one of the fastest swimmers on the planet! Everything from their bills to their body build and their crescent-shaped tails helps them shave seconds off their swim time. Scientists have recently discovered yet another adaptation that allows swordfish to swim fast: they lubricate their heads. How does it work? Read more to find out!
