Can I have a jellyfish as a pet?
Thanks to Jellyfish Art, a company now running a Kickstarter, your dream of owning a pet jellyfish could soon be a reality. Jellies are like a wet ball of tissue floating around in the tank. If they get close to a filtration intake in a regular fish tank, they would get sucked in and badly mangled.
The intelligent, 8-legged cephalopods are gaining popularity in home aquariums, but not everyone thinks they're suited for life in captivity. Octopuses can make appealing pets. They're beautiful and intelligent, and because they can live in an aquarium, they seem like they'd be low-maintenance.
- The giant Pacific octopus is considered to be long-lived compared to other species, with lifespans typically 3–5 years in the wild. Many other octopuses go through a lifespan in one year, from egg to end of life. To make up for its relatively short lifespan, the octopus is extremely prolific.
- Cephalopods grow into maturity in a very short time, from 3 – 5 years. Squids do not live a very long life, which is why females release such enormous amounts (up to 11 pounds) of eggs to ensure the continuation of their species. Squids usually spawn in groups.
- Despite their incredible range of mechanisms for both defence and attack and their obvious intelligence, cuttlefish do not live for a very long time. They live for somewhere between 18 and 24 months and the females die shortly after spawning.
Most aquatic species have fresh water and salt water varieties, however I cannot remember hearing of a freshwater cephalopod. Cephalopods include squid, cuttlefish, octopuses and nautiluses.
- Luckily for us, freshwater jellies are quite small - an adult is the size of a quarter - and there isn't any hard evidence that suggests that they can penetrate through our skin to hurt us the way larger, marine jellyfish could.
- There are seven species of freshwater cetacean: 1. Also known as the pink river dolphin or boto, the Amazon river dolphin can only live in freshwater. It is found throughout much of the Amazon and Orinoco River Basins in Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, and Venezuela.
- By the mid 1980s surveys revealed that only an estimated few hundred baiji survived; by 1990, the baiji was critically endangered - there were only thought to be 100 left and in 1997 only 13 individuals remained. The nosedive in baiji numbers was fast and shocking.
