At the Neptune Islands, 12 years of observational + acoustic data show white sharks respond to killer whale presence with short-term avoidance, not long-term disappearance. Context matters. Killer whales aren’t always a driver of shark absence. 🔗 connectsci.au/wr/article/5...

There's a reason whale song strikes a chord with humans
Most of us are familiar with whale song, but new research suggests that the structure of the song - the individual parts that make up the whole - has similarities to human language.

Did you know? When killer whales depredate from longlines, they tend to be selective—they often pick certain species while leaving others, even if on the same line. For example, in New Zealand, killer whales take school sharks and bluenose off longlines, but not hāpuku (Visser, 2000).

Hi new followers! I love creating illustrations and infographics to share information, especially when it comes to killer whales. Here is a recent one I made covering killer whales of the Gulf of Mexico (and that’s the only name I’ll ever call it 😉)
An infographic titled “Killer whales of the Gulf of Mexico” with a blue gradient background. In the center are a male and female killer whale. On the right of the male is a circular map of the Gulf of Mexico. 

Below the title reads the text “Killer whales (Orcinus orca) are rarely seen in the Gulf of Mexico, but recent research has suggested at least some individuals may regularly occur the gulf in offshore waters. A minimum of 49 individuals have been photo-identified here, and some have been resighted over a 26-year period. 

In the bottom left, there are illustrations of a sperm whale, Pygmy killer whales, and a generic dolphin. Text above them reads: “Diet: Killer whales in the Gulf of Mexico have been seen pursuing and attacking other cetaceans, such as dwarf sperm whales, dolphins, and sperm whales.”

In the bottom right, there are illustrations of two multi-colored DNA strands. Text reads: “Genetics: Two haplotypes have been found in killer whales from the Gulf of Mexico, one of which is not found elsewhere. This suggests some of the whales may be resident to the Gulf, or descendants of a unique maternal line.”
