Sex changes in nature
by Emily Makowski in Sextraordinary!
We might think of animal mating being as simple as 1 male and 1 female, like on Noah's Ark. But many types of fish undergo sex changes throughout their lives. My goal is to open people's eyes to the diversity among sex in animals.... Read more »

Cultural evolution in killer whales
by gdw in FictionalFieldwork
Auka watches mother and the other adults hunt. They are black-and-white ghosts flitting through the waters of their chilly world. Their prey is fast, agile. Coordination is key. Which is why the young ones have to stay behind. There is no place for playfulness during the hunt. But Auka doesn’t feel playful. She ignores the […]... Read more »

Burning seaweed to make glass and avoid a lumpy neck
by Rosin Cerate in Rosin Cerate
Seaweed is one of those tricky biological groups, as membership isn't just about being a close relative. It typically includes plant-like organisms found among several types of algae - green, brown, and red - and depending on who you're talking to also includes masses of cyanobacteria (which are distant relatives of algae). Functionally, all seaweeds enjoy growing in salty water and use the sun to manufacture sugary meals for themselves. Their need for sun means they are found in sunlit coastal ........ Read more »

Marine Protections Are Sorely Lacking
by Jenny Ludmer in Rooster's Report
As awareness has increased across the world, marine protection areas have more than quadrupled over the last decade. And yet, according to a new study, that’s not nearly enough. Indeed, scientists have identified tens of thousands of species that rely on largely unprotected regions of the sea. But, fortunately they’ve got a plan.... Read more »

Fish Guts and Cancer
by Mark Lasbury in As Many Exceptions As Rules
E. fishelsoni s a bacterium that breaks the rules. It grows from 10 µm long to a fully visible 0.7 mm….in twelve hours! Normally, diffusion isn’t adequate for a bacterium this big because it takes too long for two interacting proteins to find one another. But what if the bacterium make more of the protein, so much more that it can find a partner all the time. How can you make that much of each protein? E. fishelsoni does it by making 85,000 copies of its genome….. ever........ Read more »

Baby Giant Squids
by Dr. M in Deep Sea News
We know almost nothing about Giant Squids with mantles lengths less than 1000 mm (~40 inches). Very young squids are even more enigmatic than adults.

Mr. T made mohawks and fool pitying a life goal for many.
