From all cetaceans, I think I like Orcas most. Highly intelligent, social animals who are instantly recognised by nearly everybody. However, a lot of them is still unknown. Recent research divides the Orcas into different ecotypes, ecologically distinct forms of one species. But differences in behaviour, habitat choice, appearance and even in DNA indicate that they might actually be several different species. Who knows, time will tell, I guess. Anyhow, it’s really interesting research on a really interesting species.
