1 Biodiversity of Fishes Phylogeny and Remarkable Fishes Rainer Froese rfroese@geomar.de (13.11.14)

2 Phylogeny of Fishes Phylogeny –Classification based on common ancestry –Kingdom Animalia, Phylum Chordata

3 Phylogeny of Fishes Phylogeny –Classification based on common ancestry –Kingdom Animalia, Phylum Chordata Classes –Open www.FishBase.org, section Tools, select Classification Tree –Open www.FishBase.org, select Quick Identification: discuss Classes, click through to Families Fishes in Time –Open FishBase, FishBase Book, Nomenclature, The Orders Table: discuss common ancestry, show relation to tetrapods, show poster and table (next slides)

6 Remarkable Fishes Discuss: phylogeny, distribution, size, prey and predators, reproduction, growth, brain size, other traits. Myxine glutinosa Latimeria chalumnae Rhincodon typus Engraulis ringens Mola mola

7 Need To Know Based on common ancestry, the 33,000 known species of fishes are classified into 6 Classes, about 60 Orders and about 500 Families. All fishes and tetrapods had a common ancestor about 600 million years ago; tetrapods (about 27,000 species) split off from lobe-finned fishes about 400 million years ago. Know the Classes of fishes and their main characteristics

8 Phylogeny of Fishes Exercise –Select and explore some remarkable fishes based on information in FishBase –Present your findings
