Chad Johnson claims he has studied killer whales 'since birth'

It's been a little while since we heard from Chad Johnson in the United States. Ochocinco has been busy plying his trade in Canada with the Montreal Alouettes, but he took to Twitter Monday to share some thoughts on his first love: orcas.

Johnson posted a link Monday to a video of orcas killing a shark, as one does. Some guy then questioned Johnson's classification of the whales as "transient," but Johnson was having none of it. 

Look at the dorsal fin in the video, they were Transient Orcas dammit... RT @Stpinkney: @ochocinco those are offshore, not transient.

Transient diet = seals, dolphins, sea lions, porpoises & sharks RT @Stpinkney: don't think Transient eat Sharks? That's only off shore, no?

If there's one thing Chad Johnson hates, it's people questioning his marine biology credentials.

Hate when someone tries to tell me about Orcas like I haven't studied these creatures since birth...

Johnson's love of orcas is well-documented. He's kissed them on the lips and engaged in Twitter discussions with PETA about their captivity.

Don't try to flex your orca knowledge muscles against Chad Johnson.
