I've always thought shellfish were ancient, like they have been around since the dinosaurs or something.
I bet shellfish back then were much larger than they are now. T-rex was just a glorified reptile after all.
It sort of validates my theory because shellfish are part the crustacean family and they have been around for 8 millennia.
The sea is vast, so it's there are plenty undiscovered shell fish probably in the deep ocean.
That is very interesting. Believe it or not but many varieties of shellfish are closely related to insects and arachnids(spiders), making them close to the main classes of Arthropodas.
Hold on! How is that even possible. Shellfish don't even have legs like insects of any kind.
Arthropod
An arthropod (, from Greek "arthron", "joint" and "pous", "foot" (gen. ποδός)) is an invertebrate animal having an exoskeleton (external skeleton), a segmented body, and paired jointed appendages. Arthropods form the phylum Euarthropoda, which includes insects, arachnids, myriapods, and crustaceans. The term Arthropoda as originally proposed refers to a proposed grouping of Euarthropods and the phylum Onychophora.
Arthropods are characterized by their jointed limbs and cuticle made of chitin, often
poet, and of the sheepskin-costume appropriate for much of what was surrounding him.
