Orca ("type C") spyhopping

When

spyhopping, a whale rises and holds a vertical position partially out of the water, often exposing its entire rostrum and head. It is visually akin to a human treading water
. Spyhopping is controlled and slow, and can last for minutes at a time if the whale is sufficiently inquisitive about whatever it is viewing.

A dolphinarium is an aquarium for dolphins. The dolphins are usually kept in a large pool, though occasionally they may be kept in pens in the open sea, either for research or for public performances. Some dolphinariums consist of one pool where dolphins perform for the public (such as above at Loro Parque), others have expanded into much larger parks, keeping other marine animals and having other attractions.
