The Bottlenose Dolphin (Tursiops truncatus) is one of the most common and well-known dolphins.
Adults range in length from 2 to 4 meters (6 to 13 ft) and in weight from 150 to 650 kilograms (330 to 1430 lb)[2] with males being on average slightly longer and considerably heavier than females; however, in most parts of the world the adult's length is about 2.5 m (8 ft) with weight ranges from 200 to 300 kg (440 to 660 lb).

Fluking
Açores-Ilha Terceira
Sperm Whale
Flukes are lifted very high out of the water before a whale begins a deep dive.
Sperm whales are believed to be able to dive up to 3 km (1.9 miles) in depth and 90 minutes in duration to the ocean floor. More typical dives are around 400 m (437 yards) in depth and 30–45 minutes' duration and generally move in a northerly direction. They carry three tonnes of blood which holds enough oxygen to help it achieve its diving depth.

Spyhopping
Açores-Ilha TerceiraCachalote-Sperm whale

Spyhopping is the act of coming out of the water vertically, and momentarily staying out of the water in a manner akin to a human treading water. A powerful individual can spyhop as much as half of its body out of the water. The reasons for spyhopping are likely to be similar to those of breaching. Further spyhops may well be used so that the whale can examine its surroundings above the surface—for instance to look at prey species in the case of Orcas. For this a spyhop may be more useful than a breach, because the view is held steady for a longer period of time.
