What you have there is a sponge skeleton. The actual sponge animals are cellular.
Dammit.
There are two of them with that name, but six series on Animal Planet devoted to the same thing.
Animal Cops: Houston
Animal Cops: Detroit
Animal Precinct (NY City)
Miami Animal Police
Animal Planet Heroes: San Francisco
Animal Planet Heroes: Phoenix
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.
Hang on though, because sponges (or some of them at least) are definitely perforate - they pump sea water through themselves continuously.
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.
Darn you groman. Scooping me on the damn cow hole. That was mine. grumble
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.
And is there an “Animal Cops: Special Victims Unit” or a “Cold Case (of Fish)”?
In that case it would be a “Cod Case”…
Alright, don´t make a fuss, I´ll go and shoot myself now.
