http://www.telegraph.co.uk. Dolphins live in complex social groups called pods. Each pod can have from two to 12 members, which are usually family and are very close to each other. Just like humans, dolphins stay close to their families. Sometimes, if there is an abundance of food, multiple different pods come together to form a superpod, which can have over 1,000 members. Dolphins even have personalized whistles, which are like names. Studies show that orca pods even have their own “language” of clicks and whistles which they use to communicate (orcas are not actually whales, they are the largest type of dolphin). Parent dolphins sometimes punish young dolphins for misbehaving, and studies have shown that dolphins are some of the only animals who can actually recognize themselves in a mirror. “Not only that, but they also recognize changes in their appearance, showing a complex form of self awareness.” says onegreenplanet.org. Dolphins also have a remarkable amount of intelligence. Yes, dolphins and humans have some rather obvious similarities, too. We’re both mammals, we both breathe air, and we both have hair. All mammals have hair, but dolphins don’t have any that is easily visible.…
for food. The cells that frame these animals don’t have a cell wall and most of the cells are organized into tissues, which are then put into particular groups of organs for function. Dolphins can take part in many complex movements and they are very active. Most of the dolphins are diploid. That means that there are two sets of chromosomes; one from the mother and one from the father. Dolphin’s phylum is Chordata. Spinner dolphins possess a notochord at some time…
It has been known for many years that bats use echolocation to navigate and find prey in the dark. What has been left unanswered is how that when bats are flying together are not found running into each other due to interference of sound waves from their neighbours. It is known that bats do not have any problems with this interference because bats have been observed flying in swarms and capturing prey with not a problem. What scientists are now trying to discover is how the bats can get around…
The mammalian order Cetacea is composed of two parvorders, the Odontoceti (toothed whales) and the Mysticeti (baleen whales). They compromise of over 80 known living species of whales, dolphins and porpoises (Reiss & Marino, 2001; Simmonds, 2006). The compelling sets of characteristics they have acquired over their 55-60-million-year evolution including echolocation ability and complex social organisation (Hof, Chanis, & Marino, 2005) have created great belief that this order contains some of…

Common Bottlenose Dolphin: Anatomy: Common Bottlenose Dolphins are marine animals that live their whole life in the water. Their blowhole is on top of their head. Their ears are close to their eyes. They have 2 fins; a set of fins called Pectoral Fins that helps them swim. The other one is a single fin on top of their head further away from the blowhole called the Dorsal Fin that helps them keep stable against the water currents. They have a small patch of skin on their stomach that is…
techniques from their mothers, and patterns may be passed on throughout a population. Dolphins who live in shallower habitats usually make short dives, where they surface about twice a minute. Dolphins who live in deep habitats tend to make deeper dives for more than 5 minutes. (Encyclopedia of Marine Mammals) Dolphins are social creatures and their social structures vary, so much so that the patterns of inshore groups may not reflect those of populations found offshore. Based on observations,…
Dolphins’ Methods of Hunting Many organisms have developed intriguing methods to hunt their prey. This report explains the hunting methods of several species of dolphins. Relevant background information is provided. Hunting strategies are broken into two categories: individual hunting methods, and group hunting methods. Not all hunting methods belong strictly in one category; several of the methods covered are exhibited in other marine organisms. One group hunting method is unique to dolphins.…
The Slaughter of Dolphins People think that dolphins are the friendliest creatures in the ocean and no one would hurt them or even kill them. Well they are actually being killed right now. The dolphin are being slaughter in a place called Taiji, Japan. Taiji is a small town with a big secret. If you didn’t look closely, you would think they love dolphins and whales (“The Cove”). The capture of dolphins and of the killing of dolphins all started when the show called “Flipper” came out in 1964.…
Common bottlenose dolphins produce a wide variety of underwater sounds (Lammers & Oswald, 2015) allowing the detection and discrimination of the position of a sound in three-dimensional space (Mooney et al., 2008). These animals are also known for their vocal learning capabilities, with high ability to imitate other animal’s whistles, including man-made whistles or artificial sounds (Lilly, 1965; Janik & Slater, 1997; Tyack, 1997; Janik, 2000; Miksis et al., 2002). This ability comes from the…
