Slide 6
Will dolphins attack a shark and why? Generally dolphins will
not attack sharks, but in a group sometimes they have done it. They
can be curious of sharks or feed in the same area and are more
likely to be attacked by them. Some large sharks feed on Bottlenose
Dolphins. http://www.imaginecruises.com.au/research-

Slide 7
Are dolphins related to whales? Yes, dolphins & whales are
both cetaceans and very closely related. Orcas are the biggest of
the dolphins.

Slide 8
Do dolphins sleep? If so, how? No, dolphins rest half of their
brain for a few minutes at a time so they can surface and take a
breath. Anesthetic kills them.

dolphins are not the same dolphins that you would see in the ocean;
they have special adaptations to their habitat. In fact, river
dolphins are only distantly related to sea dolphins. They belong
taxonomically speaking to different families. The oceanic dolphins
belong to the family delphinidae while river dolphins belong to the
family Platanistoidea as we said above. Among the five species of
river dolphins, Amazon pink dolphins are considered the most
intelligent of them, with a brain capacity 40% larger than that of
humans. Pink dolphins inhabit the Amazon River, but they can also
be found in the Orinoco basins and the upper Madeira River as well.
While they are mostly pink, these dolphins have various colored
skins, which can be light gray, pink, or brown. The Amazon River
pink dolphins conform the largest population of river dolphins in
existence as the other four species are functionally extinct or
close to extinction. Pink dolphins

Orcas Orcas, or killer whales, are the largest of the dolphins
and one of the world's most powerful predators. They feast on
marine mammals such as seals, sea lions, and even whales, employing
teeth that can be four inches (ten centimeters) long. They are
known to grab seals right off the ice.

The Long-Finned Pilot Whale The long-finned pilot whale is not
actually a whale, but a dolphin. Along with the related
short-finned pilot whale, this species was once called a 'pothead',
as the bulbous head was thought to resemble a black cooking pot by
the early whalers that first encountered the species. The Latin
name of this genus, Globicephala, meaning 'globe head' also refers
to the shape of the head. The stocky body is black or dark grey in
colour with a white stripe passing diagonally behind the eye, a
greyish area on the belly, and an anchor-shaped grey patch on the
chin http://www.arkive.org/long-finned-pilot-
whale/globicephala-melas/
Slide 14
The Common Dolphin The short-beaked common dolphin (Delphinus
delphis) is the commonest dolphin species, but exact numbers are
unknown. It is easily identified owing to the obvious 'hourglass'
pattern on the flanks, which creates a dark V-shape below the
dorsal fin. Considerable variation in colours and patterns exists
within this species, and in 1994 a new species, the long-beaked
common dolphin was recognised, based on both anatomical and genetic
differences. http://www.arkive.org/short-beaked-common-
dolphin/delphinus-delphis/
Slide 15
The Black Dolphin The Black dolphin (scientific name:
Cephalorhynchus eutropia), is more commonly known as the Chilean
dolphin, is only found in freshwater estruaries, and coastal areas
surrounding Chile. It is a marine mammal, a member of the family
Delphinidae, part of the order of cetaceans. The species is so
named for its black coloring on its fins, tail, and back. It is
also known as the Chilean dolphin, Piebald dolphin, Southern
dolphin, and White- bellied dolphin.
