[QUOTE=jackelope] What about sponges? According to [wikipedia](http://en.wikipedia.org/wiki/Sponge), they’re technically animals, and they’ve got holes through them. [Here](http://www.cs.sbcc.net/~physics/DiscoveryCamp03/meteors/meterorites/images/Sponge.jpg) is one you can see light coming through; [here](http://www.information-bureau.com/daily/070716/Sponge2.jpg) is the same photo, but I’ve circled where you can see light coming through it. (You may all bow down to my mad Photoshop skillz.) [/QUOTE] What you have there is a sponge skeleton. The actual sponge animals are cellular. ---

[QUOTE=Zahava424] There’s a show called “Animal Cops”? Seriously? [/QUOTE] There are two of them with that name, but six series on Animal Planet devoted to the same thing.

[QUOTE=CannyDan] Great suggestion! The comb jellies are some of the most morphologically complex soft bodied creatures, as seen [here.](http://www.imagequest3d.com/catalogue/ctenophores/) [/QUOTE] Honestly, are those not just the most amazing things you’ve ever seen? Isn’t it remarkable those are actually living creatures? If I hadn’t seen jellyfish before, I’d think those were computer art pictures of alien beings. ---

They’re lovely; the Seattle Aquarium has a couple jellyfish tanks, and you could stand all day and watch them gracefully swim to and fro. ---

[QUOTE=jackelope] Dammit. [/QUOTE] Hang on though, because sponges (or some of them at least) are definitely perforate - they pump sea water through themselves continuously. ---

[QUOTE=Mangetout] Hang on though, because sponges (or some of them at least) are definitely perforate - they pump sea water through themselves continuously. [/QUOTE] I’m not sure sponges count as perforate, even if they do have holes through which they pump seawater. There are a variety of aquatic organisms which have the means to pump water through themselves for feeding or propulsion purposes (cephalopods being a good example of the latter). If sponges, count, I’d say octopuses would have to, as well. ---

I wouldn’t necessarily include all sponges, but I think there might be some that are line-of-sight perforate. ---

There are some butterflies or moths that have transparent/translucent “windows” in their wings. I have no idea whether any of them have actual holes. ---

[QUOTE=Fiver] …or a “Cold Case (of Fish)”? [/QUOTE] In that case it would be a “Cod Case”… Alright, don´t make a fuss, I´ll go and shoot myself now. [Previous page](https://boards.straightdope.com/t/animals-with-holes-in-them-are-there-any/411891.md?page=2)
