What is wrong with MR Ray's Let's Name the Species song?
MR Ray's song goes... "Oh, let's name the species, the species, the species Let's name the species that live in the sea There's porifera, coelenterata, hydrozoa, scyphozoa, anthozoa, ctenophora,bryozoas, three! Gastropoda, arthropoda, echinoderma, and some fish like you and me. Come on, sing with me. Oh...! This is phylogenetically incorrecte because MR Ray alternates between naming phyla and classes of various ocean going critters, but skips most phyla inbetween, in lieu of having them fit a cute rhyme for the movie. Further, the terms coelenterata and echinoderma are outdated, specifically because coelenterata encompasses both cnidaria (jellyfish) and ctenophora (comb-jellies) while echinoderma is technically referred to as echinodermata instead. MR Ray does a great job, but forgots to mention the other 18 fun phyla in his song (23 total), if not completely, rather because the others didn't fit his rhyme scheme.
What are the Classification of invertebrates?
They can be divided into essentially nine subdividions (phyla): -Porifera -Cnidaria -Platyhelminthes -Nematoda -Annelida -Mollusca -Arthropoda -Echinoderma -Chordata (most chordates are those with backbones, so they are usually vertebrates, but some are invertebrates)
What does echinoderm mean in Greek?
Echinoderm is from the Greek word εχινόδερμα(echinoderma), meaning "five arms".
How are lobsters and crabs similar?
they are all living things- live underwater- bilateral (i guess for a jellyfish)
What are the uncommon modes of preservation of a fossil?
Some may regard uncommon modes of a fossil preservation to be:- 1. Carbon replication of cellulosic structures as in U Carboniferous Plants etc. Also Graptolites in Silurian. 2. "Negative" or "Hollowcast" by solution (of calcareous test) in siliceous bed. 3. Substitution replication by solution effect to Pyrite, Hydrated Silica (flint) or other mineral eg Echinoderma in Cretaceous also wood of tree trunks as in Petrified Forest in Az. USA , also of Ammonites etc in Jurassic 4. "Wrapping" in a Geode, usually with 3 above
