KEMPS RIDLEY SEA TURTLE
Description: Grey to olive-grey turtles which can measure
62-70cm in length and weigh 32-50kg. They have round
to heart-shaped shells.
Habitat: Gulf of Mexico along eastern coast to Nova Scotia.
Diet: Crustaceans, fish, jellyfish.
Population: Fewer than 1000.
Reasons for decline: Increased threats to their nesting
beaches by humans who collect and disturb their eggs;
caught in shrimp fishing nets; oil spills on their feeding
grounds; pollution.
Facts: It is the rarest and most endangered of all sea turtles;
only 350 females nest a year; nests only on a 32km strip of
beach in western Gulf of Mexico.

MAUI’S DOLPHIN
Description: Maui's dolphin is the only endemic cetacean to New
Zealand. At approximately 1.4 m in length, it is one of the
smallest and most endangered groups of cetaceans. It is also the
world's smallest and rarest dolphin.
Habitat: Maui’s dolphin lives on the west coast of the North Island
between Maunganui Bluff and Whanganui.
Diet: Mullet, kahawai, arrow squid, herring, red cod.
Population: Less than 55 adults.
Reasons for decline: Sharks, orca; inshore fishing; toxoplasmosis.
Facts: Five marine mammal sanctuaries were designated in 2008
to manage nonfishing-related threats to Maui’s dolphins. Their
regulations include restrictions on mining and seismic acoustic
surveys. Further restrictions were introduced into Taranaki
waters in 2012 and 2013 to protect Maui's dolphins.

DUGONG (SEA COWS)
Description: Grey, slow moving mammal, about 3m long and
weighing about 400kg. Lives entirely in the sea and only surfaces
to breathe from nostrils near the top of its head.
Habitat: Northern coastlines of Australia, warm shallow waters in
the Pacific and Indian Oceans.
Diet: Sea grasses.
Population: About 15,000 and declining.
Reasons for decline: Destruction of seagrasses along the coastlines
due to pollution; caught in fishing nets; fall prey to killer whales,
crocodiles or large sharks as they are slow moving; slow to
reproduce (one calf every 3-7 years).
Facts: Sailors use to think that these creatures were mermaids; the
males have ivory tusks to fight other males in mating season.

CHINOOK SALMON
Description: In the ocean, the chinook has a bluish-green colour
on its back which fades to a silvery colour on the sides and white
on its belly.
Habitat: Southern California to Canadian border, east to Rocky
Mountains; Alaska (Yukon River) Lakes areas.
Diet: Plankton, insects, crustaceans, small fish.
Population: Stocks and quotas are applied to ensure that chinook
salmon are not over-harvested.

sport; they can weigh up to 57kg; largely commercially fished
using troll gear and gill-nets.
Facts: Males are deeper in colour and have a hooked nose or
upper jaw.

HUMPBACK WHALE
Description: Mostly black with white on its throat and belly. Can

Habitat: The Atlantic and North Pacific Oceans.
Diet: Krill, plankton, small fish.
Population: Fewer than 10,000.
Reasons for decline: Until recent laws were passed, the humpback
whale was hunted for its meat, oil and whalebone. Some
countries continue the whaling: Norway, Japan, Faroe Islands and
Iceland.
Facts: Spray from its blow can be seen several kilometres away;
can hold its breath for up to an hour; the males sings songs in the
mating season.
