Striped Dolphin

Also known as the Euphorosyne dolphin, the Striped dolphins are found in almost all oceans, preferably temperate and tropical oceans, and was once formerly a subspecies of bottlenose dolphin. They mainly feed on pelagic fish and squid, but they also eat octopus, krill, and other crustaceans. They reach sexual maturity around 7-9 years for ones inhabiting the Mediterranean, while the ones living in the Pacific reach sexual maturity at 12 years, their life expectancy is up to 60 years. Male Striped dolphins are larger than females, weighting 160kg (352 lbs) and 2.6 m (8.5 ft), females are only 2.4m (8ft) long and weight 150 kg (330 lb).

They move in larger groups, though are smaller in Mediterranean and Atlantic oceans. Its not uncommon for them to mix with other dolphins. There is estimated 2 million of Striped dolphins in the wild and are not endangered. Tragically as to many marine life, human interferances such as pollution, busy ship lanes, hunting, and fishing nets/gears are one of the greatest threats to Striped dolphins.

Pantropical Spotted Dolphin

The Pantropical Spotted Dolphin is a species of dolphin under the Stenella genus and are found in all tropical and temperate oceans. Pantropical Spotted Dolphins often connect with other dolphin species such as the Rough-toothed Dolphin, Short-finned Pilot Whale, and Spinner Dolphin. A key feature with Pantropical Spotted Dolphins is their speckled spottings that they develop over time until adulthood, during immaturely they can be mistaken for the common bottlenose dolphin. They have a lifespan of 46 years, hit sexual maturity at 11 years, reaching a size of 6 to 7 feet.

They mainly feast on squid, crustaceans, mesopelagic cephalopods and fish. Pantropical Spotted Dolphins are seen in along with yellowfin tuna as their diets are similar to one another. The current population of Pantropical Spotted Dolpins is 3 millions, where 2 million live in the Pacific Ocean. Some of their biggest threats is entanglement in nets, hunting (from humans), and illegal feeding and harrassment.
