Đúng là chưa bao giờ nghĩ ra thật

chứ nếu không thì chúng làm tình thế nào :D, ưu điểm là vừa làm vừa nhìn thấy rõ luôn :))

IN 2013 a group of Japanese scientists (nhà khoa học) published (công bố) a paper (nghiên cứu) describing a sea slug (sên biển) with a disposable penis (dương vật rời ra được). As strange as this sounds to us, the concept of the detachable (có thể tháo ra, gỡ ra, tách ra) penis is not a surprise to malacologists (nhà nghiên cứu động vật thân mềm), which is what we call people who study slugs, snails, octopuses, and other soft creatures.

...Think about what that means. A cephalic (ở trong đầu) penis doesn’t have a head, it grows out of your head. The snail penis looks like a fleshy dreadlock growing right near their stalked and googly eyes. At least they can see what they are doing when the deed is being done.

And suddenly I realized that snails have to carry their penis on their head, because if it were tucked inside their shell, how would they use it? I wondered why I hadn’t thought of this before, while Winston enlightened us about other anatomical oddities (điều kỳ quặc về giải phẫu học) of our molluscan brothers.

...Slugs are snails that have lost their shells, and this has allowed them to put their penis back where it belongs, which to say away from their head. When slugs have sex, they line up head to toe because their male and female bits are always on the same side of their body. The logistics of two penises and two vaginas create a complex set of sexual politics, including something quite sinister (độc ác, hung hãn, nham hiểm, đầy sát khí) in land slugs, called appellation.

The Greek prefix a- means without, and phallate means to have a penis, so it makes sense that appellate snails have no penises. The Greed prefix apo- means separation, so apophallate slugs had a penis at one point but lost it somehow. This seems particularly tragic in the case of the well-endowed banana slug, whose scientific name means “big penis”. The truth is that apophallate is a fancy word for a violent act.

Sometimes land slugs get stuck (mắc kẹt) during the sexual act. When they cannot separate after sex, according to Wikipedia, “one slug gnaws off (cắn đứt; gặm, ăn mòn) either its own or its partner’s penis”.
