Subject: Re: White Tail Deer query and right whales?
I realize right whales aren't deer but their evolutionary ancestry is similar and right whales do have cornified tissue on their heads although most patches or callosities relate to where many mammals have facial hair, eyebrows, moustache and chin whiskers There are also post-blowhole callosities which would be where horns would develop if they grew them. Cetacean skulls have been highly modified with bones either lengthened or shortened. Foreheads are very much foreshortened and the only section that might be called forehead is directly behind the blowholes.
To make a long story short, just as deer can sometimes have horns growing in abnormal locations, a right whale was born a couple of years ago with additional callosities on its back and side. I have fondly called this whale "Sponge Bob" but the whale has not been officially named. To top it off, the mother of this particular whale is an unusual mother in that when
she has a calf she heads south and took one calf to Texas in the Gulf of Mexico and the calf in question was actually born in the late spring off Cape Cod, unusual in itself, and they promptly migrated to Florida in July. It was the back callosities on the calf that allowed researchers to identify the mother and calf when in Florida because the photographs did not clearly show the head of the mother.
If anyone would like to see these strangely located callosities, go to www.gmwsrs.blogspot.com where I have posted two.
