Watch a jellyfish floating in the sea, and you might assume the animal is simply drifting along haphazardly. But some species of box jellyfish can guide themselves through complex habitats.

Behold the lowly amphioxus, and you’ll see an animal whose genes are not very different from yours.

Also known as a lancelet, amphioxus is a small, fishlike invertebrate about 2-3 inches long. Common in shallow marine waters, it burrows in the sand and filters nutrients from the water. What makes this humble creature so intriguing to scientists is its unique status as the closest living invertebrate relative of backboned animals.

But scientists believe the red knot uses a more precise method.

When a whale dies and sinks to the ocean floor, it sets in motion a new beginning for deep-sea life. Scientists call this a “whale fall,” and it moves through three fascinating stages.

A whale carcass brings a whopping amount of organic matter to a place where food is scarce. Within days, hagfishes, sleeper sharks and scavenging crustaceans arrive to feast on the remaining flesh. This first stage is called the mobile scavenger phase. Depending on the size of the carcass, the bones can be picked clean in a matter of months.
