In a new collaborative study led by Shannon Barry from @dalyengellab, we reveal that bull sharks are altering their life history to cope with warming water in the North West Atlantic.

The Ecological Fallout Of Losing White Sharks In South Africa
When top predators vanish, everything shifts. False Bay’s white shark disappearance has set off a chain reaction affecting prey, competitors, and habitats.

Following the loss of white sharks from False Bay, both seals and sevengill sharks have increased in relative abundance, coinciding with declines in small fish that seals feed on and smaller sharks that sevengills prey upon.

Did you know not all sharks need to swim to breathe?
• Many species, like the lemon shark (Negaprion brevirostirs) depicted here with @drneilhammer can rest on the bottom & buccal pump! A process where they open & close their mouth creating a vacuum pump of water over the gills

How cool is this? Not all #sharks are big. This jaw is from an adult shark of a small species (spot-tail shark).
