How about the Port Jackson and its adorable smile! I think more people should know about it!
Love your blog! 🦈💖
Thank you so much!
Port Jackson Shark // Heterodontus portusjacksoni
These cute sharks grow to be approximately 1.65 m (5.4 ft) and are found exclusively in the waters of southern Australia. The conservation status for these sharks is unknown, but their eggs have a high mortality rate (only about 11-22% survive) because of high predation.
Unlike a lot of sharks, the Port Jackson shark doesn't have a mouthful of sharp, pointy teeth. They have a front row of small, pointed teeth that lead to wide, flat teeth in the back. These teeth are handy for catching and then breaking the shells of mollusks and crustaceans.
I'd love some lemon shark facts 💛
Lemon Shark or Negaprion brevirostris
They get their name from their yellowish brown coloring. Lemon sharks, unlike the lone-shark stereotype, enjoy hanging out in groups! They even have preferred individuals to hang out with!
Lemon sharks are also one of the most well-understood shark species and this is because they do well in captivity. Additionally, most of our knowledge of shark physiology and biology stems from studies of lemon sharks!
Unfortunately, this species is nearly threatened; this is mostly due to overfishing. They're not only caught as bycatch, but are a target for some fisheries. Their meat, skin, and squalene are used for human consumption. It's estimated that between 70-90% of shark squalene harvested each year is used in cosmetics. (Make sure to do your research before buying makeup). To harvest the amount of squalene used for our consumption, almost 3 million sharks are killed every year. But there's a great new alternative source that's gaining traction: olives!
