He actually had a friend initiate contact, the only hint that Coffeezilla was involved was a nonsense sentence in the copy that had Coffeezilla as initials.

The best part, though, is that when the liason sent over the contract to be signed, the small print specifically said that the while thing was a joke at the guy's expense and the linked website would change, but he didn't read the contract closely enough and the rest is history.

Cetacean Intelligence (there's a section for communication).

It's actually really cool too; Dolphins all have something that researchers call a "signature whistle," which seems very similar to the concept of humans each having a name. And the crazier thing is, for male dolphins, a part of their signature whistle will be taken from their mother's signature whistle, while female dolphins have completely original signature whistles. So this shows not only language, but also suggests culture.

Another awesome example; there are two dolphin species, one generally lives further north while the other lives further south, but they both reproduce around Hawaii. When they meet up around Hawaii, they hunt with each other. The two species generally have vocalizations and hearing abilities that are in a different frequency range, but their frequency ranges have some overlap. So when they hunt together, they switch to making sounds that are in a frequency range that they can both hear/vocalize in. So essentially, they're using a bridge language that neither typically speaks when they're separate.

This next study, I've sadly not heard any updates on, but this company is trying to use ML to translate dolphin language. (they were supposed to have finished the study in 2021, but I never heard more about it. Hoping COVID didn't wreck it.)

Interesting, it looks like it got major revisions through the series. The first one I found ("I know I remember an Orca Gunship from somewhere" phase) has sort-of stub wings, fixed fans in the wings (takeoff assist?), and what I think are pivotable jets (TW vintage). Older TD style, as you say, is pretty much a heli form factor aside from the turbofans. One of the developers is Lancaster Lifting Body, which might imply that the hull is an airfoil, which could push it back towards plane.

I assume this has been discussed several times by now in the community!

It isn't an airplane or jet either though. I don't think there is a real category for a "jet wing". But, it's a bit closer to a helicopter in that its lift is generated by its engines which is similar to how a rotary wing gets lift from the main rotor(s) which is/are directly powered by the engine. On a fixed wing aircraft, the propeller(s) or jet engine(s) give it speed, but do little to nothing for lift. That is why (without major modifications) fixed wing aircraft don't have VTOL capabilities. (For simplicity, we are going to ignore special cases like the Ospry.) All of the lift comes from the wings on a fixed wing aircraft. The engine(s) is/are there to give enough speed to the aircraft for the wings to do their job. That is not how the Orca works. It is true it is not quite a helicopter in that a helicopter is a rotory wing aircraft, but overall, the physics of how it flies would be much more in line with a helicopter than an airplane.

IE: the evolutionary trend towards k selection vs r selection in orcas is backfiring during the current mass extinction event that is putting excessive pressure on their population numbers. In times of extreme population stress and environmental decline, passing on genes is too uncertain even with large investment in offspring and so a lot of effort is wasted compared to producing more offspring but putting in less effort for each.
