Siphopteron sea slugs are hermaphroditic, but this is not all that's unusual about their sex lives. When they mate, one of the pair just straight-up stabs the other one in the forehead with a tiny, spiky thing. It's a very direct approach! No muss, no fuss, just hormones straight into... More »
Slugs may ensure mating success with a shot to beloved’s forehead, say evolutionary biologists.
Meet Siphopteron species 1. It's a species of sea slug, recently discovered by Rolanda Lange. To procreate, two members of the species get together, stick organs into each other's heads, and fertilize. That's right — nature has at last provided us with a perfect example of the mindfuck.

A species of sea slug squirts chemicals into its partner's head during mating, perhaps in a bid to take control of its brain
Inspired by a sea slug, designers Burton Nitta envision the symbiotic, sustainable clothing of tomorrow. In the waters off the east coast of the United States, there is a small sea slug called the eastern emerald elysia that feeds by...Show More Summary
Some brief reviews for anime I watched during the winter and spring this year. From the New World – 5/5 One of the best anime I’ve seen, not to mention one of the most unique. Great storytelling, directing, characters, animation, atmosphere, world-building, music, and pacing. I recently watched some AMVs of this and all the [...]
Researchers found that a type of predatory sea slug with a simple nervous system has more complex cognitive abilities than previously thought, allowing it to learn the warning cues of dangerous prey and avoid them in the future.
CHAMPAIGN, Ill. — Researchers have found that a type of predatory sea slug that usually isn't picky when it comes to what it eats has more complex cognitive abilities than previously thought, allowing it to learn the warning cues of dangerous prey and thereby avoid them in the future. The research appears in the Journal of Experimental Biology. read more
I’ve been meaning to start having some manga reviews on Sea Slugs, but I thought I’d add a little twist to the formula. In this post I’ll announce what manga I’m going to read, and then I’ll have the actual review in a week or two. That way other people who want to read the [...]
After almost four decades of absence from local waters, a special sea slug appears to be making a comeback, and marine scientists are eagerly anticipating its return.

Sea slugs are weird. But their sexual habits are even weirder. Take Chromodoris reticulata for example. It's a "simultaneous hermaphrodite," meaning it has both male and female sexual organs which it uses at the same time when mating (making it the envy of the animal kingdom). Show More Summary
A penis would rank pretty high on any list of body parts you'd want to be able to grow back if lost. The more replacement penises the better. And for the first time, Japanese biologists have found an animal that can do just that. Mo...
Add this to the huge list of strangest animal mating habits we've posted on Neatorama a while back: the hermaphrodite Chromodoris reticulata sea slug has a disposable penis that snaps off every time it finishes mating. (But don't fret, Neatoramanauts, it has got spare penises) Like almost all nudibranchs, C.reticulata is a hermaphrodite. Show More Summary
"A sea slug that is able to detach, re-grow and then re-use its penis has surprised scientists." [BBC]
Relax: none of those things on top are dongs (I think). This is the Chromodoris reticulata species of sea slug. While it's generally accepted that all sea slugs have unusual sex practices, this species is particularly interesting to scientists because it can shed, regrow, and reuse its penis. Show More Summary
THE BBC has a very interesting report on a sea slug found in the Pacific Ocean.. A sea slug that is able to detach, re-grow and then re-use its penis has surprised scientists. … They believe this is the first creature known that can repeatedly copulate with what they describe as a “disposable penis”. – [...]
Red and white sea slugs that roam the warm waters of Southeast Asia just may be the envy of the animal world given their ability to discard and re-grow a penis again and again. The Chromodoris reticulata is a hermaphroditic slug that, once mating is complete, can cast off its penis into the water. And [...]
