They have a long, flexible tail which is used for wrapping around weeds for support. They swim I upright position, their movements being helped by a rapidly oscillating fin on their back. The male sea – horse lays her eggs in this pouch.
The most remarkable thing about the sea – horse is that part of the process of reproduction is taken over by the male creature. One the female sea – horse has laid her eggs in the male creature’s pouch, she leaves. The hatching of the egg is done by the male fish. Mating begins with the male and the female sea – horses doing courtship dance. The male and female creatures swim around each other in circles.
At the end of the dance, the male appears to bow to its partner; but in actually, the male is banding to pump water from his pouch. Next, the female fish lays eggs into the male’s pouch. About two hundred eggs are laid. The pouch, then close up. The female sea-horse now swims away, leaving the male sea-horse to do hatching.
The eggs are hatched about a month later. The young sea-horses are ejected from the male creature’s pouch by means of muscular contractions. The sea – horse feeds on tiny fish the creatures sucking them into its month.
SilkWarms
Silkworms live for only two or three days after laying eggs. About 36.000 to 50.000 eggs are laid, and these are carefully stored at the silkworm farm until they are ready to hatch.
The eggs hatch into caterpillars, which feed on mulberry leaves. Soon the caterpillars are ready to spin their cocoons. Not all caterpillars can spin silk cocoons. Only the caterpillars of a silkworm moth known as ‘Bombyx mori’ can do such spinning.
This caterpillar has special glands which secrete liquid silk through its lower lip. The liquid produced later hardens to form fine strands. The caterpillar makes its cocoons using these strands.
The threads on the outside of the cocoons are rough, while those inside are soft and smooth.Some fully-spun cocoons are heated. This kills the pupa inside. The cocoons are then put into hot water to loosen the fine threads. Finally, these threads are reeled off the cocoons.
The length of unbroken thread produced by a single cocoon measures about one-and –a-half kilometers. Being twisted together several of these threads make single woven materials.
