Time for some trivia – this time, it is on dolphins….
- Dolphins have between 84 and 116 teeth – but they don’t use them for chewing. They don’t have a gag reflex like humans do so their teeth are only used for gripping and tearing
- Dolphins use echolocation to find food and predators – scientists have now proven the teeth in the bottom jaw actually help get the signals back to the brain
- In recent times, scientists have actually worked out that the Indo-Pacific Bottlenose Dolphin (Tursiops aduncus – Bella, above, is a Indo-Pacific Bottlenose Dolphin) is a separate genus to the Common Bottlenose Dolphin (Tursiops truncatus)
- Dolphins use a form of camouflage called counter shading – darker top to blend in with the dark depths, lighter bottom to blend in with the shallower water
- Related to the lack of gag reflex touched on in point 1, dolphin calves use their tongues to be able to drink milk from their mother. The tongue has frills on the outer edges about a third of the way up and they will fold their tongue into a “straw” which allows the mother to squirt the milk into the calf’s mouth which they then swallow
- The easiest way to tell the age of an Indo-Pacific Bottlenose Dolphin is to look on their belly – the more spots the animal has, the older it is
- Dolphins eat their food head first – if they were to eat it tail first, they would end up with scales lodged in their throat as the scales would lift up and off. Eating it head first lays the scales flat on the body of the fish
- If you were to pat a dolphin, chances are you would liken them to a hard-boiled egg without the shell. This is true – they also feel like a wet tyre tube
- When a dolphin exhales, the air that is exhaled contains nasal discharge as well as expired air…. the feeling of that is extremely gross!
That’s it from me – feel free to ask me if you have any questions!
