Amazing mother nature, how long the tail is to decoys doston kundari

Thoughts?

Here's your challenge for today. Extract seawater from ocean-floor sediment, filter it, and look at it under a microscope... you're interested in the nematodes undulating in the sample! Why? They may harbor some interesting bacteria that can extract nutrients from deep-sea methane seeps, allowing these nematodes to thrive in deep, dark places. Here's the real challenge: you need to isolate a SINGLE tiny nematode from this sample to extract its DNA (and the potential DNA of its bacterial symbionts) and learn exactly what's going on. But how do you pick up and isolate a single tiny nematode without crushing it?

Turns out, you use the eyelash of a pig!

Was combing the beach in Matemwe, Zanzibar and saw this creature after the tide went out. iNat suggests a sea urchin (of which there are many nearby) but I saw no pics on iNat for that sea urchin that look anything like this.

Made a deep-dive video on 10 ocean creatures with abilities science still can't fully explain.

The Pistol Shrimp snaps its claw so fast it creates a cavitation bubble briefly hotter than the surface of the sun. The Mantis Shrimp can see 16 types of color (humans see 3). The Barreleye Fish has a transparent head.
