This week we are literally diving into the topic of crustaceans and how they're related to insects, but that's not all. Let's also take a closer look at lobsters and learn some interesting history.

Welcome to episode 63 of Insects for fun! Only today we’re not talking about insects exclusively. This is a bridge episode which is going to link us into all further episodes relating to crustaceans because there’s a lot and I don’t want to have to keep explaining their relationship every time. SO! Here we go (underwater bubbles)
Remember that episode I did talking about how not all insects are bugs but all bugs are insects? Well here’s a new one for ya. All insects are actually crustaceans, but not all crustaceans aren’t insects (HUH) and no, spiders, scorpions, millipedes, centipedes, and horseshoe crabs are not crustaceans which means that yes, lobsters, shrimp and crabs are more closely related to insects than arachnids, and those other creepy crawly arthropods. Let’s go back in time to where it all began which would be the Cambrian period. At this time the earth did have land masses but Pangea was not a thing, and these land masses were very very bare. Almost all life was still in the ocean and it was here that Crustaceans first came into existence.
So what do Crustaceans and Insects have in common then? Well, for starters they both rely on an exoskeleton made of chitin, and they both start out as an egg and go through a series of molts to reach their adult stage. They also both have compound eyes and antennae! Yeah that’s right, even crabs have antennae, and crazier still is that crustaceans actually have two pairs of antennae unlike insects which only have one. But the similarities go deeper than this, and by that I’m referring to their insides. Both of them share the same proteins for transporting oxygen, and they’re circulatory systems are also controlled by the same peptides. I think it’s safe to say that yes. Insects are indeed crustaceans, and when we eat shrimp, crab and lobster, we’re basically just eating big ocean bugs.
But are Lobsters really just roaches of the sea? How did that myth even start in the first place? Believe it or not there was a time when Lobsters were actually referred to as the poor man’s chicken or even cockroaches of the sea in the United States. Back in the 1600 and 1700s the full potential of a lobster's taste had yet to be unlocked and people really didn’t know how delicious they could be. As a result piles and piles of lobsters would wash up on the shores and people didn’t know what to do with them because they certainly weren’t going to eat them. But the reason lobsters began to really pique people’s interest started with the transportation system. As more and more railroads were being built, and more and more passengers were riding trains for longer periods of time; food had to be made available and what better than to offer cheap and common Lobster! More and more people began eating lobster and became curious about the methods one could cook it, and now here we are. Lobster is considered a delicacy and fetches a high price.
So now that we have the knowledge of what a crustacean is, and the history of lobsters in the states. Let’s look at what exactly a Lobster is, and come to a conclusion as to whether they’re indeed overpriced cockroaches or not.
Not all lobsters are the same, and many crustaceans which have lobster in the name are not true lobsters. Today we are looking specifically at clawed lobsters in the family Nephropidae of which there are around 54! Not too many which is kind of surprising, and I think there must be more as well considerin
