The description of fish larvae mentions "Lack the two symmetrical fins and the transparent body of Chaethognaths." but the name "chaethognath" is not used elsewhere (and should be spelled chaetognath anyway, with no middle h).
Replace by "Lack the two symmetrical fins and the transparent body of arrow worms."
