New critter...can anyone ID?

[Rendos]

It is growing on the underside of a montipora colony.

I thought it was a tunicate at first, but I am not so sure. It is almost completely transparent. It opens and closes when something touches it.

Anyone???

 

[joeycadre]

looks like a sea squirt or something

You're both right

You're both right

You're both right, it is a tunicate (aka sea squirt). Notice the incurrent siphon on the side and excurrent siphon at the top.

Of all the critters your tank, this one bears the closest relationship (from an evolutionary point of view) to humans (it is Phylum Urochordata; in the juvenile form is has several chordate characteristics, as do we!)

Sorry, there I go into professor mode again... hazards of the job.

I thought it was because of the in hole and out hole.

Nah, I can think of quite a few slimy critters with 2 holes! And many of them aren't **** sapiens.

not including fish, right?

 

[joeycadre]

i saw a thing on discovery about sea squirts, and yes they are very very closely related to human beings supposedly. and they're just as weird as people it seems.

 

[neuroslicer]

not including the fish, of course...

now for bonus credit, what's the next closest invertebrate critter in your tank in terms of relatedness on the geologic time scale??? (well you may not have one of these... but if you did!)

ah, Nick is taking evolution... this one should be cake for you!

 

[willember]

Urchins and Starfish?

Did you censor the word ****** or did the censor catch it and change it? I can't believe it wouldn't allow the word homosapiens to be censored.

Willem wins the evolution prize! Or was it Jennifer? (I was going to provide a hint: "it kinda don't matta to me", but the hint was not needed!). Animals from the Phylum Echinodermata (sea urchins, sea stars, brittle stars) have embryonic development very similar to vertebrates, including humans. That's why a lot of scientists that study human embryonic development do research on sea urching eggs!

And no, I didn't edit **** sapiens. Imagine what the censors would do with the hominid species **** erectus! Whew!

Oh sorry I get it now!
Well didn't really get it or anything.
This is just bad.

Stay out of this dave!
