That's a good question about these seals. We are identifying them on TAI as grey seals while Schleich website identify them as harbor seals. I don't remember very well the discussion about them but I think it was related with the white color of the pup. This is a feature much more common in grey seals than in harbor seals. Though, their faces, have the nostrils closer to the usual v-shaped ones of harbor seals. It is actually an interesting question and if we agree they're harbours, we could change it at Toy Animal Wiki.
The king penguin is a different question. Here there is no doubts, Schleich released a king penguin and later introduced chicks of a different species, the emperor penguin. It is easy to mix both species but not when they are chicks. So, Schleich, replaced the king penguin adult for a emperor penguin and fixed it. Papo is often also very generic identifying some species.
