Sorry guys, I've been really busy.
Here's some stories from the gift shop!
Molting, or shedding the outer skin is the most dangerous period in the life of a crustacean.
The outer shell doesn't grow with them and needs to be carefully shed, but because of all the small spines and details on their body they can become easily trapped in the shed and die.
This horseshoe crab was almost done shedding when his rear legs became caught in the shed, killing him.
It's a really incredible specimen, his ghostly transparent skin still caught alongside his body.
This is a cleaner shrimp (Periclimines sarasvati). Cleaner shrimp are often found living on coral, sponges, or anemones. Their see-through bodies allow them to blend in with their homes and avoid detection by predators. However, this can make it difficult for their food sources to find them. That's because cleaner shrimp eat the parasites and dead skin off of fish. So fish will seek out these shrimp when they need some help getting cleaned up. The relationship fish and cleaner shrimp have is called mutualism; a relationship that both organisms benefit from. To help fish locate them, the shrimp advertise their services by waving their antennae to get their attention. Some studies have also shown that fish will use coral heads and anemones as visual cues to find the shrimp. Sometimes cleaner shrimp will even treat drivers to a quick manicure!
