The torpedo genus contains 13 species of cartilaginous fish, also known as electric rays (for their ability to produce electricity for defense+predation). The naval weapon system was named after them!

"Hey Torpedo?"
"Yeah what's up Shark?"
"You know that time you swam, like, into that rock? And it fell over?"
"Aw man can we stop bringing that up that was so embarrassing."
"Nah man, nah, nah. The humans saw it, they saw it man, and GET THIS..."
Assassin bugs stab other bugs with their faces and suck the life out of 'em.
In Japan, many animal names are a string of words (fragments, often) that go from the specific to the general, often taxonomically. Thus, true bugs are called kame-mushi (turtle bugs). We call a particular superfamily of true bugs "shield bugs", so the name makes sense if Japanese taxonomists discovered shield bugs first and all the less-shieldy bugs later.
Particular subgroups therein have names ending in kame-mushi, like the kin-kamemushi ("gold turtle bugs", what we call jewel bugs.) Why I've brought the assassin bug to your attention is because they're known as sashi-kamemushi, or stabbing turtle bugs.
The specimen in the photo, Agriosphodrus dohrni (no common English name), is known as the Yokozuna-sashi-kame. The sumo-champion stabbing turtle.
