Did you know they drive dolphin pods into the killing cove where they are slaughtered by sharp objects being driven into them to sever their spinal chords and blocking up their blow holes with corks so they drown in their own blood? It happens in Taiji. Every. Single. Year. They do this for several reasons.
The fisherman in Taiji are driven by greed. They selectively hand pick dolphins (the pretty ones) out of pods and slaughter the rest to sell to their unsuspecting customers around Japan and elsewhere. They have been known to dump the babies back out to sea. Dolphins are very emotionally connected mammals. They have been known not to leave family members who are injured or sick.
We imagine most do not survive.
I personally have always thought they do that to lure other pods in. I'm sure the babies are crying in distress after seeing their family murdered in front of them and may linger outside the Cove. Please spread the word, every chance you get that captivity kills. We can all do our part in some way.
