Anatomy of large marine vertebrates

Program

4 CFU (48 hours)

Anatomy of Elasmobranchs

Topics of the course will be:

 

Arguments

Specific contents

 

External anatomy

 

External organization and anatomy of elasmobranchs: body shape, fins, head, tail; how can external morphology help us for the taxonomic identification

Evolution

Evolution and classification: placoderms and other ancestors; Cladoselache; Carcharocles; Classification of modern elasmobranchs

Reproductive organs

 

Male and female reproductive systems. Spermiogenesis and ovogenesis. Uterus and anatomical adaptations for pregnancy

Interaction with the environment

Locomotory system: muscles, skeleton, integument; swimming and floating: the role of the liver

 

Brain and sensorial system; role of sense organs: case studies in controlled and field conditions; the microbiome of skin and the immune system

 

Feeding

 

Feeding: teeth: evolution, morphology and function; the stomach and the spiral valve; how anatomy can help to understand feeding strategies; stable isotopes and trace elements analysis to understand the diet of a shark

Anatomy of sea turtles

Anatomy of marine mammals

Topics of the course will be:
