The ocean on the south shore of Long Island really starts lighting up with life this time of year. Along with tropical fish and startles, we also get some sharks that are better known to more southern waters. The most common shark I have seen in the last few years is the Hammerhead. They seem to like the surface. I’m not sure of the species, but I would guess scalloped hammerhead. (Hit the comments if you can identify!) They are definitely feeding on the bunker (first pic). These sharks are amazing to watch. They are extremely maneuverable, and slice and dice through the ball up bait.
Its been found that unusually structured vertebrae are what allow this tight maneuvering. That crazy head – the Cephalofoil – helps with lift and turning, however its main function is more of a sensory organ. All sharks have electroreceptors called ampullae of Lorenzini that help detect prey. By spreading these out over the wider area of the cephalofoil, it acts like a radio antenna, allowing the shark to sweep broader areas for prey.
While we wait for this south wind to calm, here are some older pics from last year, this week.
I suspect little photoshop on that last one, but look at that water. Thats real! Hit the comments for any questions or um.. comments! Enjoy!
