7. External anatomy of the Lobster
The body of a lobster is segmented.
The appendages (antennae, pincers, legs, etc), are jointed.
The body is covered by an exoskeleton made of chitin
The exoskeleton requires them to molt as they grow, in a process called ecdysis.
9. Like dolphins, lobsters use
complicated signals to establish
social relationships. They
sometimes walk hand-in-hand, the
old leading the young.
To escape from enemies,
lobsters swim backwards by
flipping their tail.

They eat……..
Lobster’s feeding
sea urchins.
mussels
sea stars
clams
snails
fish
25. When we consider the lobster fishery in Sri Lanka, both of
these methods are used.
After catching the lobsters ,they are brought to lobster
collecting centers.
They are kept in marine water tanks with an oxygen supply
until transport.

35. Health Benefits of Lobsters
Lobsters are low in fat content, making them one of the best
choices for health conscious people. The high content of protein
makes this food beneficial, especially for athletes.
Lobsters are low in cholesterol and thereby, they assist in
maintaining triglyceride levels in the body and keeping the heart
healthy.
Like other seafood, lobsters are also a good source of omega
3-fatty acids that are essential for the proper functioning of the
heart and brain.
36. These fatty acids help in lowering the risk of arrhythmias,
which can lead to sudden cardiac deaths. Furthermore, the
compounds in lobsters facilitate in reducing the growth
rate of atherosclerotic plaque and lowering the blood
pressure.
Lobster can be very effective in preventing various health
disorders such as osteoporosis, osteoarthritis, rheumatoid
arthritis, cardiovascular disease, colon cancer and chronic
conditions involving bone, connective tissue, heart and
blood vessels.
Zinc found in lobsters is necessary for increasing
activities of the brain, boosting the immune system and
preventing loss of vision. In addition, this mineral also
effectively heals injuries in body tissues.
37. Phosphorus, found in abundance in lobsters, aids in the formation
of teeth and bones. It facilitates the rate of metabolism, enhances
the functioning of kidneys and lessens joint pain.
Being a great source of vitamin B12, lobsters also help in
maintaining the red blood cells and nerve cells. It improves the
symptoms of Alzheimer’s disease and prevents other neurological
problems.
Lobsters possess the trace element, selenium, which is beneficial
for triggering the activity of thyroid glands as well as the immune
system. Selenium is known to protect the body cells against free
radicals during the process of metabolism, apart from monitoring the
oxidation of cholesterol to prevent coronary artery disease.
38. General weight of an adult
lobster is about 1 or 1.5 kg
1kg is marketed
approximately Rs 2000 to
Rs 3000
39. There is a high market for the live lobsters.
Therefore there is a threat of overfishing.
So legislations are required.
Fisher folk should be aware about sustainable utilization.
Conservation plans should be prepared and launched .
It may be a grate service to protect lobsters not only as a food
source, but also as an important component of marine
biodiversity.
