Name that critter

[little koala]

Thank you bmathison1972!

OK, here were go - what are these?

[Badger]

Well, they're sand dollars/sea biscuits of some kind. If necessary, I'll let one of the next few posters be more specific.

[little koala]

Hey Badger,

You're spot on! No need to be more specific. That means it's your turn to post a picture for us to have a guess at what it is. 

[Isidro]

Found them, they are Dendraster excentricus.

You're right Isidro, thanks!

[AnimalToyForum]

New creature:

Oh oh oh, I know this one!

It's a fish!

[Isidro]

It reminded me somewhat a young tigerfish, so I'm pointing in the right direction with an African tetra (Alestidae)?

[Badger]

Yes, little Jonny, it's a fish. Now you can have your freetime!

Nope, not even close: For one, it's a fish from a temperate area, and it isn't closely related.

If it helps, here is a (possibly) less confusing photo:

The picture is a bit small, do you have a larger version?

My first thought is gizzard shad or something similar.

[Badger]

No.

I don't have a larger version of that specific image, but here is a different larger image.

[Isidro]

Oh, that last drawing is very clearing and eye-opening! Now I see that it must be a Coregonus sp. The problem is... which one?

[Badger]

Yes, it is a Coregonus sp.

As for the species, there are actually 2 possible answers I'll accept, as one of the answers is considered by some to be synomynous with the other.

A hint for one of the answers; one of the common names for this species is misleading, as it is considered VU on the IUCN Red List.

[Isidro]

With these hints it's impossible to not find it!
Of the 13 species of Coregonus that are classified as Vulnerable in IUCN, only 3 have a possible double-answer due to synonymy or taxonomic confusion:
Coregonus confusus has been considered conspecific with Coregonus candidus (both are VU)
Coregonus lavaretus is a name widely used for all Eurasian Coregonus in the past
Coregonus maraena is still locally called Coregonus lavaretus

For the two firts I didn't found none of your images, but for the thirs, while I can't find the two photos, I've found the drawing. Hence, it is Coregonus maraena.

[AnimalToyForum]

Honest question - how can you tell? What is the giveaway characteristic of this genus?

[Badger]

For the two firts I didn't found none of your images, but for the thirs, while I can't find the two photos, I've found the drawing. Hence, it is Coregonus maraena.

Debatably correct.

The answer that I implied was supposed to be C. lavaretus, but as you point out, C. maraena is still locally considered the aforomentioned species.

The other answer I would have initially accepted was C. pennantii, which is widely considered a synonym of C. lavaretus. You get to pick the next species, mostly because you were the only one that recognised it even at genus level.


EDIT:

With these hints it's impossible to not find it!

I meant that only one of the species in the double answer had a misleading name, because it was Vunerable in IUCN.

EDIT 2: Although, well done for over-analysing it even further than I intended.

[Isidro]

Ah, that's why I never would find it, because Coregonus pennantii is not Vulnerable, it's Critically Endangered.

@animaltoyforum I almost never identify animals and plants by concrete features, but by the general looking and what I know in my memory. The first photo gave me a very vague impression of alestid characin, the drawing however gave me a very clear impression of a Coregonus.

Well, this will be my first photo n the thread. And an easy one, I hope:

[Badger]

Is it a Vancouver Island Marmot?

[Isidro]

It is!
