We order urchins, mussels, mysids, etc. on a regular basis and when the boxes arrive we have to put them in flow through sea water tanks or drip bowls. Sometimes, there's a stowaway in the shipment! These animals are designated work pets and they have their own tanks. They're a bit different than the trout - the trout exists because we are a sick bunch of people and want to see how big he can get.
Alternatively, the work pets put some time and effort into sneaking into those specimen boxes and we all have our favorite little critters.
Pet tank selfie:
You can see that there are a wide variety of animals. We have a bat star, spined star, lots of brittle stars, urchins, a few different anemones, shrimp, and we had a lion's mane nudibranch at one point (may he rest in peace). My favorite animal in these tanks is the crab!
He looks friendly right?
No. I will not stick my hand in there if he is not distracted by food. His speed is considerable.
He also gets along well with his tank mates.
An escape has happened at least once. Perching on sea urchins is probably how he managed to get out of the tank in the first place. He went missing for an entire week before he was found and the poor guy was whole, minus a front claw. Considering he'd fallen the equivalent of 100 stories in crab measurements a missing claw isn't bad. It does not seem to hinder his mussel cracking skills, but most likely contributes to his bad attitude. Also, there is a cover on his tank now.
Most of these work pets were put into the tanks when they were fairly small, or else someone would have surely noticed them hiding away when sending us live animal shipments. While the crab and sea stars have grown a lot, we have a few babies that were recently added.
I thought I had found the smallest purple sea urchin last week that I'd ever seen before:
BUT a few days after this, Eric found a baby urchin hiding under an adult urchin in a recently delivered shipment. It's SO TINY.
We also have abalone!
I have only ever seen one abalone in the wild because their numbers are so low and I stare at these guys all the time. Have you ever seen one eat? They use their radula (essentially a tongue file) to scrape algae.
This is the last blog post before Terry and I get back from Hawaii because we are going to go watch this girl get married!!!
