Splake is a hybrid between lake and brook trout, which means that it resembles both parent species quite a bit. Splake are both smaller and darker than lakers. The splake’s tail isn’t as deeply forked as that of the lake trout, and splake have fewer appendages on their intestinal tract.
While rainbow trouts are true trouts, lake trouts are actually char. Lakers have dark bodies with light spots, while rainbow trout have light bodies with dark Spots. Rainbow trout have a broad, reddish stripe along their lateral line, which lake trouts lack entirely.
