Workout moves

In my aquarium, something, probably a crab, dug an eelgrass' roots out of the sand, leaving it floating upside-down, roots near the surface. Looks like fun, a little hermit crab said, and climbed up to practice his trapeze artist skills.

Head down

Feet up

Balancing on the bar

He's got a few holes in his shell. One is big enough to expose his backside.

The stripy section is the back of his cephalothorax, his head/thorax section. The abdomen is curled up in the bottom of the shell, as it lies here. There are a couple of holes there, too. Good fresh water circulation!

And then he climbed down again and went to pester the anemones.

En mi acuario, alguien, probablemente un cangrejo, excavó las raices de una planta Zostera marina, dejándola flotando con las raices para arriba, cerca de la superficie del agua. Un cangrejito ermitaño, Pagurus hirsutiusculus, la vió y decidió ir a practicar sus habilidades de trapecista.

Tiene varios agujeros en la concha que lleva, uno bastante grande. Se le ve el cefalotórax en este. El abdomen queda en la parte inferior de la concha, como está dispuesta en la última foto, pero ahí también hay un par de agujeros. ¡Ventilación!

Y terminado el ejercicio, se regresó a la arena y fue a molestar a las anémonas.
