Have you ever heard of the Nervous Shark (Carcharhinus cautus)?

It gets its name from its skittishness when approached by people! This shy shark can be found in Northern Australia, the Solomon Islands, & Papua New Guinea. Love it!

Hello there Shark Twitter! I'm Leo, a shark & top predator ecologist, & I'm watching and live-tweeting with #IsleofJaws

Feel free to ask questions & I'm excited to see what they find! #SharkWeek

I'm glad to hear them talking about the top threat to sharks worldwide, which is fishing pressure!

Bycatch (accidental capture while fishing which often kills them) is the biggest threat! Finning, & recreational fishing also contribute! #MonsterMako #SharkWeek

Mako sharks are the fastest sharks in the ocean! @TheRock is right!

At burst speeds of up to 42mph (68km/hr), these are absolutely flying through the water!

Always interesting to understand the pattern of shark movements throughout the day and at dusk. This is incredibly important data & can help with the issue of coexistence!

Did you know our intestines are about 25x the length of sharks'?!

This is because sharks have corkscrew-shaped intestines that maximize surface area over a short length! Our intestines are 25ft long & a comparably sized shark would be 1ft!

Nice to see both beautiful sharks & invasive species removal at once! I do wonder if the sharks have a Pavlovian association with spear guns or not? To them the rubber band snap might be like a dinner bell.

@mcmsharksxx @KatCollins2 Ooo that is tough. I'm going to go with the porbeagle shark with its light ombre!

@WhySharksMatter

Did you know Porbeagle Sharks (Lamna nasus) can live in almost freezing waters?!

It's so cold humans would lose consciousness in <15 mins! These sharks survive by warming important parts of their body up, called regional endothermy!
