I think it’s so cool when orcas porpoise. Because it’s like, “yes we are dolphin. cute normal dolphin playing in waves.”
(Just huger and with freaking-giant dorsals.)

Not everyone likes to rest. Often juveniles stay active while the pod snoozes.

Actually, all cetaceans except for Amazon river dolphins have u-shaped pupils when they are contracted. It’s just very difficult to see due to the dark pigment in the iris. Here’s a drawing of it:
(When they are expanded they do become oval-shaped, however.)
Here’s a paper that extrapolates a bit more on that.
Super rare Footage of the World’s Fastest Whale
by Jason G. Goldman
One lucky research assistant caught a rare show in the Straits of Gibraltar last week, as a fin whale was spotted breaching the water three times in a row, right in front of her. While fin whales do sometimes breach, it’s rarely seen and even more rarely caught on camera.
The videographer, Séréna, is a summer research assistant with CIRCE, a Spain-based cetacean conservation, research, and education organization.
Fin whales (Balaenoptera physalus) are the second largest creatures on our planet, just after blue whales. When you consider that the average fin whale needs to hurl its 80+ tons and 89+ feet out of the water and into the air, the spectacle becomes even more amazing. As one of the fastest whales in the world, the fin can reach cruising speeds of 23 mph with short bursts up to 29 mph. (The Sei whale may beat it for short sprints up t0 40mph, but not for cruising speed.) Their impressive speed has given Fin whales the nickname “greyhounds of the deep.”
**Mind the sound, the water sound is a bit loud. Sorry!
I shot this with a GoPro Hero2 off the coast of Lana’i. The camera was attached to a pole mount over the side of the raft.
Note: The camera was never “dropped” in on top of the dolphins but rather put in before they approached so they could choose to come over or not. As you can see they didn’t seem to take an issue with it.
