The Portuguese man o' war (Physalia physalis), also known as the man-of-war, bluebottle, or floating terror. It is found in the Atlantic Ocean and the Indian Ocean.

Fathers Who Give Birth

For most animals, giving birth is a female's responsibility. But definitely, this 'childbirth thing' does not hold applicable to all creatures. In the animal kingdom, the male seahorse is the one who gets pregnant. The male seahorse is equipped with a pouch on his front side. During mating season, the female seahorse deposits the eggs in the male's abdominal pouch, where they are fertilized. The male seahorse holds the eggs until they are hatched and then he expels them out in the water.

Believe it not, in reality, snakes do not have external ears and thus, they can't hear like how we hear the sound. The snake charmer continuously sways the flute and the snake moves to the swaying movement and not on hearing the music.

All Mammals are not Same

Usually, in mammals the fertilization is internal and most mammals are viviparous. But not all, there are some exceptions. Monotremes are egg-laying mammals that are strictly found in Australia and New Guinea. The characteristic that distinguishes monotremes from other mammals is that they lay eggs, monotremes lactate, but lack nipples. Examples of monotreme are the Echidna and Platypus. Another type of mammal is marsupials. Marsupial mammals are endemic to Australia and America. The characteristic that distinguishes them from placentals is that they give birth to underdeveloped embryos that innately climb into the mother's pouch. The most common marsupials are kangaroos, koalas, opossums, and wombats.
