It is also observed that female dolphins tend to live a longer life in the wild than their male counterparts. There is evidence of individual bottlenose dolphins living in the wild more than 60 years old. So, if you can check the number of layers present in the cross-section of the dolphin teeth, it will be easier for you to estimate the dolphin’s age.Įven though the average lifespan of the bottlenose dolphins is about 30 years in the wild, they can live for a long time. So just like the growth ring you can observe in the trees, you can also see similar kinds of annual layers in the cross-section of dolphins teeth. Dolphins come with only a single set of teeth, growing a little bit each year. There are some characteristic features of the dolphins that can give the observer an estimate of their age.įor example, you can check the cross-section of the dolphin’s tooth to find out how old the animal is. In captivity, it is easy for the observers to guess the age of the dolphins as, in most cases, they have been observing these marine animals since they were newborn babies. It is not as easy to find out the dolphin’s age as you may think it is. Human Impact How to find out the age of a dolphin?.However, when you see a bottlenose dolphin playing in the bow wake from a boat, perfectly in sync with its companions, living in balance with its surroundings, it’s hard not to feel a bit of envy. It is impossible to say whether humans or dolphins are “smarter,” because the skills needed to succeed in each of our environments are so different. They have an abundance of “spindle cells” which guide reasoning, communicating and problem solving, and they are able to recognize themselves in a mirror at seven months of age – five months earlier on average than human babies can. Their brain-to-body ratio is second only to humans, and the complexity of their brains, indicated by the amount of folding in the cortex, exceeds ours. Scientists are just beginning to understand the depth and extent of dolphin intelligence. This not only allows companions to find each other when they are not in visual contact, they can also use each other’s signature whistles to address a specific dolphin. Each dolphin develops a unique whistle by the time they are a year old that remains relatively constant throughout their lifetime. These dolphins are also known for having individual “signature” whistles. When the fish start leaping to escape the temporary enclosure, the rest of the dolphins will move in and snatch the fish out of the air. ![]() When feeding in shallow waters, they engage in cooperative feeding, where the leader will use its tail to create a “net” of sediment to encircle a school of fish. The limbic system in their brains, the area that processes emotions, is more complex than in the human brain, and it is believed that social interactions are critical to their emotional wellbeing. ![]() ![]() Nearshore, they congregate in small groups of approximately 10, but offshore they sometimes gather in pods of up to 100 individuals. Over a 50-year lifespan they can grow to be 12 feet long and weigh more than 1,200 pounds.īottlenose dolphins are highly social animals. Bottlenose dolphins ( Tursiops truncates) are the most common dolphin in Florida’s coastal waters.
