Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.
This episode marks our 5th year anniversary! I also finally got the ebook download codes sent to everyone who backed the Kickstarter at that level. The paperback and hardback books will hopefully be ready for me to order by the end of February and I can get them mailed out to backers as soon as humanly possible. Then I’ll focus on the audiobook! A few Kickstarter backers still haven’t responded to the survey, either with their mailing address for a physical book or for names and birthdays for the birthday shout-outs, so if that’s you, please get that information to me!
Anyway, happy birthday to Strange Animals Podcast and let’s learn about some animals new to science in 2021!
It’s easy to think that with all the animals already known, and all the people in the world, surely there aren’t very many new animals that haven’t been discovered yet. But the world is a really big place and parts of it, especially the oceans, have hardly been explored by scientists.
It can be confusing to talk about when an animal was discovered because there are multiple parts to a scientific discovery. The first part is actually finding an animal that the field scientists think might be new to science. Then they have to study the animal and compare it to known animals to determine whether it can be considered a new species or subspecies. Then they ultimately need to publish an official scientific description and give the new animal a scientific name. This process often takes years.
That’s what happened with the emperor dumbo octopus, which was first discovered in 2016. Only one individual was captured by a deep-sea rover and unfortunately it didn’t survive being brought to the surface. Instead of dissecting the body to study the internal organs, because it’s so rare, the research team decided to make a detailed 3D scan of the octopus’s body instead and see if that gave them enough information.
They approached a German medical center that specializes in brain and neurological issues, who agreed to make a scan of the octopus. It turned out that the scan was so detailed and clear that it actually worked better than dissection, plus it was non-invasive so the preserved octopus body is still intact and can be studied by other scientists. Not only that, the scan is available online for other scientists to study without them having to travel to Germany.
The emperor dumbo octopus grows around a foot long, or 30 cm, and has large fins on the sides of its mantle that look like elephant ears. There are 45 species of dumbo octopus known and ...
