The Humpback Whale has the longest pectoral fins of any whale. The fin alone can be a staggering 5 metres long.
These flippers are one of the features of a Humpback that discourages Killer Whales from attacking them when they're adults. One blow from a barnacle-lined pectoral fin could be enough to kill a Killer Whale.
This Humpback Whale was pectoral slapping: repeatedly raising and slapping its pectoral fin on the surface. Studies in the Southern Hemisphere have suggested that "surface active" behaviours like pectoral slapping, breaching or tail-lobbing are linked to communication. One study, by the University of Queensland, strongly suggested that this pectoral slapping was linked to short-distance communication. They found an increase in these pectoral slapping when another whale joined the group, or they were about to split up.
Humpback Whales are the most studied whale, and even so, we still have far more questions than answers when it comes to these giants.
Show me your pectoral fin! 💪👈 deze vis heeft ze zeker!
For you @laurencharms
! When whale watching, we got treated to seeing a humpback whale wave Jr.’s pectoral fin at us! This is a bit choppy as it’s a series of photos but you get the idea! #whale #humpbackwhale #pectoralfin

The humpback whale is said to have one of the largest appendages in the entire animal kingdom. Their pectoral fins can reach one third of their body length. 🐋

I swam for 40 mins before I went up to the cliff and had meditated, so I was in tune, and the whales had much to say 💙🐋👂 #whalemedicine
