As the title states, it is a continuation of my earlier Hello hello blog and it was a request from my father's good friend who had loved reading Hello hello part-1, to write a second part mentioning about communication in aquatic creatures.

It is true that marine mammals posses excellent communication skills as it was also mentioned in the first part of this blog stating whales known to posses infra sound communication especially baleen whales (baleen whales are those that have bristle like teeth, remember the whale in which Dory & Marlin of Finding Nemo, end up inside of) which also includes rorquals i.e. large ones like blue whales, humpback whales etc.
Apart from that, whales are known to communicate underwater with other sounds which are common in many animals some of which travel for long distances. The purposes for such communication can be many, like, to stay in touch with the gam (group of whales is known as gam), to attract mates(courtship) etc. For instance, Humpback whales are one of the vocal species known for emitting wide varieties of noises, such as howls, lows (akin to that of cattle), grunts ,groans, whistles etc. Right whales are known to emit trumpets,belches etc.

Sounds crazy to mention hippos in a blog of aquatic animals! well, they are partly land and partly water beasts, but the surprise is that hippos are more related to cetaceans ( whales and dolphins) than to other large terrestrial herbivores. Also, it will be good to mention that hippos are known to grunt, bellow and emit infra sound even when underwater.
