They were voracious predators, gobbling up anything that crossed their path, including worms, shrimp and other marine creatures. The phallic-shaped animals, officially known as priapulids, emerged during the 'Cambrian explosion', a period of rapid evolutionary development about half a billion years ago, when most major animal groups first appear in the fossil record.
"Modern penis worms have been pushed to the margins of life, generally living in extreme underwater environments," added Dr Smith. "But during the Cambrian, they were fearsome beasts, and extremely successful ones at that."
This crazy, hairpiece-looking clump of yellow fluff is actually a rare caterpillar that only looks like Donald Trump's hair.
Interestingly, and coincidentally, approaching the Donald Trump Caterpillar (scientific name: Megalopyge opercularis) can be very dangerous, particularly if you come in contact with the business end of its yellow mane.
"If you touch that thing, it would seriously hurt," Torres, a field biologist, told the UK Daily Mail. "It has these little hairs that can poke into your skin and release a venom."
Just like the real Donald Trump. How uncanny!
Previously, previously, previously, previously, previously, previously, previously, previously.
I agree that the caterpillar looks like Trump's hair, but while that worm is vaguely phallic in the sense that anything elongated is, I'm not sure if I'd call it penis-like.
Or am I the one with the weird-shaped penis?
The important takeaway here is that "penis worm" is the official nomenclature, even in Latin.
Shaft. Knob. Pubes. Yep, that's a penis.
I was reading this in a feed reader, so I saw the Donald Trump headline first and the picture only after scrolling. So freakin' funny.
