Grey seals freed after reconvalescence

This 30 May 2018 video from Texel island in the Netherlands says about itself (translated):

Five seals from our [Ecomare museum] shelter were able to return to the sea today! Among them were the two seals that had ended up in the shelter because they had become entangled in pieces of fishing nets. Co and Lenja, and the other three gray seals Monster, Brechje and Funny are now strong and healthy enough to be able to continue independently. The seals almost went into the water at the same time … a new future. Read more about it here.

If discovered as fossils, grey and ringed seals are so different that they could be classified as belonging to different families. Yet, a seal pup born in 1929 was found to be an almost perfect intermediate between the species. Compared to Neanderthals and modern humans, grey and ringed seals are genetically and dentally at least twice as different, suggesting that there may be more fossil human hybrids to be discovered: here.
