Horse Conch Meets Snail, Hermit Habitat Opens Up

Click on this screenshot to view the video.

THE FIRST PART OF THIS VIDEO OUTTAKE FROM BBC’S BLUE PLANET is amazing enough. A giant Florida horse conch (Triplofusus papillosus) chases, catches, dines on a smaller tulip snail (Fasciolaria tulipa). To some, perhaps gruesome but it’s part of the web of life.

KEEP WATCHING            

What happens then is equally engaging. A real estate battle follows almost immediately as hermit crabs (any of several species in Family Diogenidae) scramble to take up the snail’s newly vacated shell. The winner does so by  moving in while the horse conch is still ingesting.
