A great close up of remoras hitching a ride on a whale shark (Rhincodon typus). Remoras, or shark suckers are members of the bony fish family Echeneidae. They use a suction cup–disc on top of their heads to attach themselves to larger animals such as sharks, turtles and manta rays. This commensal relationship benefits the remoras by giving them a free ride and access to food scraps while the host animal benefits from the removal of parasites. However, I am curious how much extra drag (and energy expenditure) the presence of remoras exert on the host.
Ancient mariners feared remoras, believing these fish had the power to slow or even stop a ship by attaching themselves to it. In fact, the word remora means "delay" in Latin. ... Roasted Salted Sunflower Seeds, 5 Pound Box
I'm jealous of this love affair between diver and 🦈 shark. It's a happy healthy love story. 💦
I'm laughing at the one where the wee shark is headbutting his reg...so darn cute.
Ugggh... I'm sorry, I'm going to be that guy. Habituating wildlife to human interaction isn't the cute story the news often makes it out to be. This kind of thing usually puts both humans and animals at greater risk of injury or otherwise.
Narwhals (Monodon monoceros) on the surface. The tusks are actually one of two teeth male narwhals possess. The left tooth grows out of the skull while the right tooth remains within. Females also have two teeth, but only about 15% have the tooth grow out. The tusk has no enamel coating and its function(s) are not well understood. It is known that the tusk can sense environmental conditions (salinity), that males use it to contest for mates and it has been documented as an aid in catching fish. Just what the meaning of the tapping is in this video is unknown. ... Bamboo Bread Box Wood, Roll Top Small Wooden Biodegradable Toast
