9. Loggerhead turtles are named for their large
heads that support powerful jaw muscles,
allowing them to crush hard-shelled prey like
clams and sea urchins. They are less likely to be
hunted for their meat or shell compared to other
sea turtles. Bycatch, the accidental capture of
marine animals in fishing gear, is a serious
problem for loggerhead turtles because they
frequently come in contact with fisheries.
10. Loggerheads are the most common turtle in the
Mediterranean, nesting on beaches from Greece
and Turkey to Israel and Libya. Many of their
nesting beaches are under threat from tourism
development. Sea turtles are the living
representatives of a group of reptiles that has
existed on Earth and travelled our seas for the
last 100 million years. They are a fundamental
link in marine ecosystems and help maintain the
health of coral reefs and sea grass beds.J
11. Feedings:
The loggerhead sea turtle is omnivorous, feeding mainly on
bottom-dwelling invertebrates, such as gastropods, bivalves, and
decapods. It has a greater list of known prey than any other sea
turtle. Other food items include sponges, corals, sea pens,
polychaete worms, sea anemones, cephalopods, barnacles,
brachiopods, isopods, insects, bryozoans, sea urchins, sand dollars,
sea cucumbers, starfish, fish , hatchling turtles , algae, and
vascular plants. During migration through the open sea,
loggerheads eat jellyfish, floating molluscs, floating egg clusters,
squid, and flying fish.
12. THREAT`s TO THE LOGGERHEAD TURTLES
ARE:
Worldwide, hundreds of thousands of sea turtles
a year are accidentally caught in shrimp trawl
nets, on longline hooks and in fishing gillnets—a
threat known as bycatch. Sea turtles need to
reach the surface to breathe, and therefore
many drown once caught. Loggerheads are
highly migratory and are very likely to come in
contact with a fishery, particularly in shrimp
gillnets and longlines.
16. The greater one-horned rhino is the largest of the
rhino species. Once found across the entire northern
part of the Indian sub-continent, rhino populations
were severely depleted as they were hunted for
sport and killed as agricultural pests. This pushed
the species very close to extinction in the early 20th
century and by 1975 there were only 600
individuals surviving in the wild.
Thanks to rigorous conservation efforts, their
numbers have increased dramatically since 1975. By
2012, conservation efforts saw the population grow
to over 3,000 in the Terai Arc Landscape of India
and Nepal, and the grasslands of Assam and north
Bengal in northeast India.
17. Indian rhinoceros are grazers. Their diets
consist almost entirely of grasses, but they also
eat leaves, branches of shrubs and trees, fruits,
and submerged and floating aquatic plants.
They feed in the mornings and evenings. They
use their prehensile lips to grasp grass stems,
bend the stem down, bite off the top, and then
eat the grass. They tackle very tall grasses or
saplings by walking over the plant, with legs on
both sides and using the weight of their bodies
to push the end of the plant down to the level of
the mouth. Mothers also use this technique to
make food edible for their calves. They drink for
a minute or two at a time, often imbibing water
filled with rhinoceros urine.
21. The Canary Islands quail (Coturnix gomerae) once
occurred on the islands of El Hierro, La Palma,
Tenerife and Fuerteventura (Canary Islands,
Spain). It might also have inhabited Gran Canaria
and Lanzarote, but there are no remains found on
these islands.
Because of lack of information this is all that is
known of the specie.
