A little snail fur hydroid (Hydractinia) close up for #ToxinTuesday. This female colony has tons of eggs developing across multiple reproductive polyps (called gonozooids).

This sea anemone holds some serious stinging power around their mouth!

📷 Transgenic Nematostella where green marks developing and mature stinging cells, which are densely packed around the mouth.

Close up image through microscope of the mouth and surrounding tentacles of an adult starlet sea anemone. The green spots all around the animal are developing or mature stinging cells. The green is most dense around the mouth.

Okay so jellyfish often live as polyps for a while, but polyps don’t sting right?

Not so! The polyp stage also contains stinging cells, which house the venom-filled structures that give jellies their sting.

Close up of slide of jellyfish polyps, which are whiteish in color and hanging their tentacles down. In the center is an orange-red early jellyfish about to pop off of one polyp.

And box jellyfish? Seems odd…

In more ways than one! Cubozoans or box jellies have cube-shaped bells and 1 or more tentacles at each of the four “corners”. Some species are known for having complex eyes, fast swimming speeds, or potent venoms!

Full animals image of winged box jellyfish (Alatina alata) against black background. The jellyfish is translucent blue in color and longer than is wide, with a domed top. A single tentacle that is whiteish in color streams from corners of the cube shaped bell.

We teach that poisons are harmful substances, toxins are natural poisons, and venoms are harmful substances produced by animals, containing one or more poisons. #ToxinTuesday #semanticsThursday
