Apparently This Is A Thing So I Drew Myself On It @kiraprismart Should I Be Tagging You?

Apparently the Congo river is deep enough that there are several species of fish with cavedwelling adaptations (near-total to total blindness, loss of pigmentation, etc) because light doesn't reach where they live. the fuck

There are three morphologies of dorsal fins: nearly divided, continuous, and clearly divided.

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!
