Thresher species tend to vary in base color: common threshers are typically dark green, bigeye brown, and pelagic blue. However, appearance to the observer can be altered by lighting conditions and water clarity.
OH YEAH, I got to stick vaseline coated cotton balls up juvenile Port Jackson Sharks’ noses today! They are super cute and secrete mucus when you frighten them!! Also, I discovered if you stroke their tail while holding them they just flop and lie still, I am the shark whisperer :DDD
To be honest, I don´t like Orcas and mostly because I am afraid of them. I would maybe cage dive with a great white, but never with an Orca. They are so smart and have such a strong predator instinct, it would find a way to break the cage or something.
Check out this article looking at how precise and targeted their killing and ¨butchering¨ is and who would win in a fight Orca vs Great White.
