The size of cetaceans’ organs is also “pretty variable,” she told me: A harbour porpoise has a penis the “length of my forearm,” she explained, whereas the common dolphin’s is about the size of a human hand. (This research used one female and one male of each species.)Oct 10, 2017
Perhaps the hardest part about studying marine mammal reproductive anatomy using organs collected from deceased animals is that they can’t get an erection the easy way.
Adult male bottlenose dolphins are often heavier and larger than females. The length of an adult bottlenose dolphin can range from 8.2 ft to 11.5 ft., although some only reach 6.6 ft. in size, while others grow to 13.1 ft.
Oral sex has been observed throughout the animal kingdom, from dolphins to primates.
But they’re not embarrassed! Dolphins actually DO blush (their bellies turn pink). … Instead, it’s a way that dolphins dump excess heat when they’re active, especially during summer months in Florida.
This period of advertised fertility is known as oestrus, “estrus” or heat. In species that experience estrus, females are generally only receptive to copulation while they are in heat (dolphins are an exception).

–Dolphins kill their own babies. Baby dolphins have washed up alongside the dead porpoises, and some scientists think that all the porpoise-slaughter was just practice for some old-fashioned infanticide .
About the Dolphin
Most dolphins are less than 10 feet in length, though they range considerably in size, the smallest being the Maui dolphin and the largest being the orca, or killer whale. They are intelligent, social and playful creatures.
Dolphins are very tactile and social. They show affection for each other by rubbing each other with their pectoral fins. When actual mating occurs, it is completed very quickly, with the two dolphins swimming belly-to-belly during intercourse.
Their final color can be influenced by their behavior, diet, capillary placement, and exposure to sunlight. They can be anywhere from mostly gray with some pink spots, to almost flamingo pink. The best part is, when this species of dolphin gets excited, they can flush bright pink, similar to humans blushing.
Dolphins do not mate for life, but they do create strong social bonds with their pod members. These bonds extend beyond companionship to caregiving — dolphins have been known to give special protection and aid to those in their pod that are ill or injured.
Dolphins are mammals that live in pods and are very clever. They know how to protect themselves. When they see an aggressive shark, they immediately attack it with the whole pod. This is why sharks avoid pods with many dolphins.
But female killer whales are generally smaller than elephant cows—four tons against five—and the largest elephants are larger than the largest killer whales, reaching nearly 12 tons, whereas killer whales, to my knowledge, have never been recorded as larger than about ten.
about 3 inches
Orcas’ teeth, numbering about 45 and each measuring about 3 inches (7.6 centimeters) long, are shaped for ripping and tearing prey. Orcas do not chew their food. They can swallow small seals and sea lions whole. The prey slides down the orcas’ throats!
No, dolphins do not eat people. While the killer whale can be observed eating fish, squid, and octopus along with large animals such as sea lions, seals, walruses, penguins, dolphins (yes, they eat dolphins), and whales, they do not appear to have any desire towards eating humans. …
A dolphin can live out of water for hours IF it is kept wet and cool. One of the biggest dangers to a dolphin being out of water is their inability to regulate their body temperature.
Dolphins also help people in need, reaching out to humans with compassion in ways that some people consider to be miraculous. Throughout history, people have reported dolphins helping people in perilous situations at sea — from people who were drowning to people being attacked by sharks.
Jaw claps and jaw pops: dolphins can produce extremely loud sounds by rapidly clamping their jaws together. This behavior bangs their teeth together, producing an acoustic signal that transmits large distances. Jaw claps are generally understood to be an aggressive signal, used as a threat.
