Crustaceans   (Crustacea)
Category: Invertebrates

 

 

This very large group of arthropods includes familiar animals such as shrimp, crabs, lobsters, crayfish, and barnacles. Like other arthropods, they have an exoskeleton which they must molt in order to grow. Crustaceans are distinct in their possession of two-parted (biramous) limbs and unique larval form. They are an important source of food for humans, with over 10 million tons being produced via farming and fishing every year. Most crustaceans are aquatic, though a few are adapted to a terrestrial lifestyle.

Cephalopods: Masterminds of the Ocean.

Octopi, cuttlefish, and squids - all cephalopods - have been observed engaging in amazing feats of intelligence (perhaps unsurprising, as cuttlefish and octopuses have the highest brain-to-body mass of all invertebrates). Their suction-cup covered arms are dexterous, and octopuses have been observed putting them to use throwing rocks, opening screw-top jars, even picking up and gathering coconut shells to build fortresses for themselves. Squids, for their part, have been observed hunting cooperatively and are able to communicate with one another via color changes, patterns, and flashing to one another - sometimes using different sides of their bodies to broadcast different signals to multiple squids! Just how smart are they? As they are typically elusive and so very different from humans, we aren’t sure yet - but we do know the question is not “Are they are intelligent?” but “How intelligent are they?”
