Have you ever watched a whale breathing and wondered why it seems to be spewing water ? Well, what you’ve seen is not actually the whale ‘spitting out’ water but an intricate part of its respiratory process. In this article, we delve into the mystery surrounding the ‘water blows’ of these marine giants, shedding light on their unique respiratory anatomy and unveiling how they manage to breathe underwater.
The Mystery of Marine Giants’ Water Spouts
The Mistaken Water Spout
Contrary to common belief, whales do not spit out water. What might seem like water spouting from whales is in fact a powerful blast of air mixed with condensing moisture. When a whale exhales the air from its lungs through the blowholes located on top of its head, a visible spout, often mistaken as water spray, appears.
The Famed Whale Blow
This visible spout or ‘blow’, characteristic of every species of whale, can reach varying heights depending on the species. For instance, the blue whale’s blow can rise up to nine meters high.
With that cleared up, let’s move onto understanding more about the remarkable respiratory system that allows these creatures to create such fascinating displays.
Decoding The Respiratory Anatomy of Whales
A Brief Overview
Like all mammals, whales have lungs and respire by inhaling air into them. However, unlike most other mammals, they breathe through openings called ‘blowholes’ located at the top of their heads.
The Unique Role of Blowholes
The purposeful location enables them to surface for air while keeping most of their bodies submerged. It’s through these blowholes that the exhaled air and condensation create the famous spouts.
Now, how exactly do these aquatic mammals manage to breathe underwater for extended periods ? Let’s find out.
How Whales Breathe Underwater ?
The Art of Holding Breath
Whales are equipped with an incredible ability to hold their breath underwater for several minutes. Prior to diving deep into the ocean, whales fill their lungs with fresh air and then plunge down. Their body efficiently uses this stored oxygen allowing them to remain submerged for a substantial amount of time.
Resurfacing and Breathing
When they resurface, they exhale the used air in a forceful blow and quickly inhale fresh oxygen-rich air before submerging again. This efficient ‘hit-and-run’ style respiratory cycle enables whales to spend most of their lives in the deep sea without sacrificing their need for terrestrial air.
Moving on from breathing habits, let’s explore some other intriguing functions served by these spouting behaviors.
Different Functions of Whales’ Blows
A Means of Communication
Beyond mere respiration, whales utilize their blows as means of communication. The distinctive spray pattern and sound provide cues about a whale’s identity or location, critical during migration seasons.
An Exercise Regime for Younglings
In addition, young whales sometimes breach out of water creating dramatic sprays; this is believed to be a form of exercise strengthening their muscular structure.
We hope this exploration has given you new insights into the fascinating world of these marine giants. The next time you see a « spout », remember – it’s not just a spray of water, but a glimpse into the complex biology and behavior of these incredible creatures.
