In his 1956 book The Marlinspike Sailor, marine illustrator Hervey Garrett Smith wrote that rope is “probably the most remarkable product known to mankind.” On its own, a stray thread cannot accomplish much. But when several fibers are twisted into yarn, and yarn into strands, and strands into string or rope, a once feeble thing becomes both strong and flexible—a hybrid material of limitless possibility. A string can cut, choke, and trip; it can also link, bandage, and reel. String makes it possible to sew, to shoot an arrow, to strum a chord. It’s difficult to think of an aspect of human culture that is not laced through with some form of string or rope; it has helped us develop shelter, clothing, agriculture, weaponry, art, mathematics, and oral hygiene. Without string, our ancestors could not have domesticated horses and cattle or efficiently plowed the earth to grow crops. If not for rope, the great stone monuments of the world—Stonehenge, the Pyramids at Giza, the moai of Easter Island—would still be recumbent. In a fiberless world, the age of naval exploration would never have happened; early light bulbs would have lacked suitable filaments; the pendulum would never have inspired advances in physics and timekeeping; and there would be no Golden Gate Bridge, no tennis shoes, no Beethoven’s fifth symphony.
“Everybody knows about fire and the wheel, but string is one of the most powerful tools and really the most overlooked,” says Saskia Wolsak, an ethnobotanist at the University of British Columbia who recently began a PhD on the cultural history of string. “It’s relatively invisible until you start looking for it. Then you see it everywhere.”

Cephalopod lovers, meet the stubby bobtail (Rossia pacifica)! With a mantle length of only up to 2 in (5 cm), this tiny critter typically spends its days buried beneath the sand, emerging at night to feed. Shrimp comprise nearly 80% of this species’ diet, but it also preys on small fishes and even other cephalopods. It can be found in coastal waters from Japan to California.

I heard that sharks and rays are super closely related. Are skates an approximate bridging “group” between them? Or are they outside of both groups
Tumblr media
They are all really closely related- there in all the same class known as Chondrichthyes, or cartilaginous fish. Sharks evolved first, approximately 350 million years ago during the Carboniferous period. Skates and ray came around at approximately the same time as each other 150 million years ago during the Jurassic period.
So skates aren't really a "bridging group", they're actually most closely related to rays!

Did you know? Blue-ringed octopuses (members of the genus Hapalochlaena) are among the world’s deadliest cephalopods. Found in coral reefs in the Indian and Pacific oceans, these critters typically measure less than 8 in (20.3 cm) long. But, they pack a venomous bite that is potent enough to instantly paralyze, and even kill, a human being.
