New genetic analysis have shown, that Orcinus orca consists at least of 4-10 several species:

Finding cryptic species complexes withing established species is becoming more and more common, especially with the molecular capabilities. Personally I think a 'genotype' should have a corresponding 'phenotype' even if it's not morphological. In many cases, the differences are genetic and geographic, which are impossible to separate in a toy or figure (unless the manufacturer marketed it from a specific geographic region). As such, segregating toy orca into various species will probably be impossible until 1) new species are described and 2) toys are marketed to those at the species level. I have not read this orca article, but these are just trends I have seen with the animals I study.

Honestly, let the brands first figure out how to make a decent looking orca with all the marking correct before we even dare to speak about the different types of orca! Or figure out the gender of these animals... The only two good looking orcas in my opinion are the Mojo Fun one and the Schleich 2012 orca. Both have all the correct markings to be a real good looking orca. Yet the gender specifics are doubtful with these two (bigger dorsal and pectoral fins for males, smaller for females, no genital splits on both.)

Yet, it is unknown if all types of orca are several species. Then, there would be 10 different species:)
Yes, I North that the Schleich Orca from 2013 is one of the best ones. And I think it could be a Type 2 Eastern North Atlantic Orca, because of the faintes saddle, the common shape of this saddle and the colouration.

That is very interesting ! I have often wondered why orcas could look so different, but it could just be age, sex, temperature of the water, how fat it is etc , - but it can also be because they are different species Very Happy

I think the new Schleich Orca from 2018 could be a Resident Orca. I've seen that some researchers sighted a Resident Orca without a saddle patch near British Columbia.

Then we have loads of resident orcas among our toys. But that's possible.

Are you sure they are species and not just breeds?

Yes, according to different papers, there are at least 4-5 species or even more. Their mitochondrial DNA have shown many differences. And whales are well known for their strong genes, which are not so easy to mutate.
