Few animals seem less animal-like than sea cucumbers. The long, slender beings often appear motionless like the vegetable they resemble as they bask on the seafloor. They lack a brain, eyes or obvious features apart from a mouth and anus. But there’s a lot more to these simple creatures than meets the eye. knowablemagazine.org/content/a #MarineScience #KnowableMagazine #ScienceMastodon

Knowable Magazine | Annual ReviewsWeird and wondrous sea cucumbersThese spiny or slimy ocean creatures display an astonishing diversity of appearances, behaviors and lifestyles. Many are increasingly threatened.

👀 On our radar: Fighting bird flu with lasers

💬 “Farmers know that wild birds such as geese, ducks, and seagulls spread bird flu along their migration routes, and lasers are becoming a go-to tactic for keeping them — and by extension, the virus — away from buildings or pastures.”

A carnivorous caterpillar dubbed the “bone collector” decorates itself with the body parts of its prey. Attaching an ant head here or beetle abdomen there seems to minimize the caterpillar’s own scent, allowing it to lurk in spiderwebs, where it can scavenge dead or dying insects.

How did a toxic fungus become soy sauce superstar?

Scientists think that the domestication of a microbe could go something like this:

It exists, along with other microbes, in the wild, where environmental factors such as temperature and humidity vary (bottom left).

Over time, it becomes adapted to the stable, comfortable food environment (middle) and eventually exists as a pure culture in a very controlled environment.
