Nudibranch Ecology and ID Course

Nudibranchs, and other sea slugs, are a diverse and fascinating group of marine gastropods that have developed very colorful and ornate forms. Apart from being a favorite sighting by divers and photographers, their biodiversity is an indicator of total reef diversity, and also can be used when assessing changes in the physical or biological composition of marine areas in the face of disturbances. In our course you will learn about the ecology and taxonomy of sea slugs, and about how to conduct scientific surveys to monitor their abundance and diversity.

 

Prerequisites

  • Be certified as an advanced diver under a leading diving organization (PADI, SSI, etc) (must include at least 1 deep dive)
  • Demonstrate proper diving ability at an Advanced Level and be proficient in buoyancy and self-awareness.
  • Complete the invertebrate survey of the Ecological Monitoring Program

 

Standards

  • Be able to differentiate between different types of sea slugs using anatomical differences
  • Learn about different survey methods (endo-benthic, quadrat sampling) used to survey for marine invertebrates in the muck.
  • Be familiar with the hierarchical structure of taxonomy (phyla to species).
  • Learn about the differences between morphological and molecular identification for marine invertebrates.
  • Understand the ecological and economic role of sea slugs globally

 

Requirements

  • Attend the nudibranch and sea slug lecture
  • Conduct a minimum of 2 different muck survey techniques.
  • Conduct muck surveys at a minimum of 2 different sites.
  • Complete identification of 2 different species (photos) using online and library resources
  • Locate and identify a sea slug during an EMP invertebrate survey

 

Expected course time about 8 hours
