And, of course, by now everyone’s heard of Blackfish, the documentary about Tilikum the orca, who has killed three people so far. So, yes, dolphins do attack humans. Those attacks are very rare, especially compared to human’s attacks on dolphins. But, still, they do happen.

Dolphins and porpoises differ in their faces, fins, and body shapes. Dolphins have longer noses, bigger mouths, more curved dorsal fins, and longer, leaner bodies than porpoises. The Northeastern Offshore Spotted Dolphin, shown here, has a falcate, or sickle-shaped dorsal fin and light spotting on the belly.

They thought the porpoises might have been killed by weapons tests until they found the toothmarks. Later, dolphins were caught on film pulping the baby porpoises-the dolphins even used their ecolocation to aim their blow at the porpoises’ vital organs.” 5. Dolphins kill their own babies. Males are known to kill off babies.

The PCB burden carried by male and female whales, dolphins and porpoises tends to increase until they reach sexual maturity. After that point, males continue to absorb PCBs from their food. However, the PCB burden carried by female whales, dolphins and porpoises drops off after they have their first calf, because the females pass on most of their PCB burden to their first-born calves.

Dolphins tend to have prominent, elongated “beaks” and cone-shaped teeth, while porpoises have smaller mouths and spade-shaped teeth. The dolphin’s hooked or curved dorsal fin (the one in the middle of the animal’s back) also differs from the porpoise’s triangular dorsal fin. Generally speaking, dolphin bodies are leaner, and porpoises’ are portly.

At least 44 species of dolphins (6 river dolphins) and 6 species of porpoises populate the ocean waters. Dolphins can be found swimming in all of the worlds major oceans though most species tend to prefer living in warmer climates in and around the equator due to their small size and thin layer of blubber, which makes it difficult to stay warm in extremely cold environments. Porpoises live in all shallow, relatively cold coastal seas.

Scientific studies suggest that the metabolism of whales, dolphins and porpoises are particularly ill equipped to deal with large amounts of PCBs. Scientists have found compelling evidence that whales, dolphins and porpoises make few of the enzymes that many other species of animals use to break down dangerous chemicals such as PCBs.

Pollution is the introduction of contaminants – deliberately or accidentally - into our seas and oceans. It can cause harm and long term impact to whales, dolphins and porpoises and of course, their home, the wider marine environment.

In general, dolphins make two kinds of sounds, “whistles” and “clicks” (listen to the false killer whales on this page). Clicks are used to sense their surroundings through echolocation, while they use whistles to communicate with other members of their species and very likely, with other species too.

When sleeping , dolphins often rest motionless at the surface of the water, breathing regularly or they may swim very slowly and steadily, close to the surface. In shallow water, dolphins sometimes sleep on the seabed rising regularly to the surface to breath.
Common bottlenose dolphins (referred to hereafter simply as bottlenose dolphins) are found throughout the world in both offshore and coastal waters, including harbors, bays, gulfs, and estuaries of temperate and tropical waters (estuaries are the areas where rivers meet the sea). They are one of the most well-studied marine mammals in the wild.

Dolphins use a plethora of defense mechanisms to defend themselves from danger. These include using their vast intelligence, incredible speed, communication, echolocation, and traveling in pods. In fact, dolphins are able to scare off and intimidate their main predator (sharks) just by swimming in large groups.
A group of dolphins is called a pod. Dolphins are social mammals that interact with one another, swim together, protect each other, and hunt for food as a team. Pod life plays a very important role in protecting dolphins from predators such as sharks. Most pods contain anywhere from 2 – 30 dolphins depending on the species and the situation, however there are occasions when pods gather…
