Hunting with a Suckerfish - When I walk my pet Remora!

Quick midweek video to cheer you up. This little guy didn't figure it out, that a snorkeling, diving or swimming human is maybe not the best host to live with. Their front dorsal fins have evolved to enable them to adhere by suction to smooth surfaces and they spend their lives clinging to a host animal such as a whale, turtle, shark or ray. They don't really know what a human is and are curious to find out more about that potential host. It is probably a mutualistic arrangement as the remora can move around on the host, removing ectoparasites and loose flakes of skin, while benefiting from the protection provided by the host and the constant flow of water across its gills. Although it was initially believed that remoras fed off particulate matter from the host's meals, this has been shown to be false; in reality, their diets are composed primarily of host feces. That was not happening and the Remora remained hungry. This little guy didn't give up hope for quit a while and he joined us everyday for a hunt ;-)
