The Torpedo californica, more widely known as the Pacific electric ray is endemic to the coastal waters of the north-eastern Pacific ocean, from Baja California to British Columbia. It measures up to 4.6 feet or 1.4 metres long and inhabits sandy flats, rocky reefs and kelp forests. The Pacific electric ray is a solitary and nocturnal creature that is known to act aggressively if provoked. It can generate up to 45 volts of electricity which can potentially incapacitate a diver.
Ambystoma mexicanum; a neotenic salamander, closely related to the Tiger Salamander. Larvae of this species fail to undergo metamorphosis, so the adults remain aquatic and gilled. It is also called ajolote (which is also a common name for different types of salamander). The species originates from numerous lakes, such as Lake Xochimilco underlying Mexico City. Axolotls are used extensively in scientific research due to their ability to regenerate limbs.
The Turritopsis nutricula originated from the Caribbean, but has spread all over the world due to its amazing ability. This jellyfish is about as wide as a human’s pinky nail when fully grown. It is better known as the immortal jellyfish and is capable of reverting back to its juvenile form in a cell development process called transdifferentiation. Once it has become sexually mature and mated, the jellyfish will literally reverse the aging process and will completely return to its younger self. Scientists believe that this process can repeat indefinitely, rendering the jellyfish potentially immortal. The immortal jellyfish may be the only animal in the world to have truly ‘discovered the fountain of youth’.
