Welcome to the fascinating world of vampire invertebrates and symbiotic partnerships! Nature always surprises us with its intricate and complex relationships between different species. Symbiotic partnerships can be found everywhere, from rainforests to urban landscapes to the vast oceans. Today, we will delve into the unique world of blood-feeding marine invertebrates and the microbial wonders contributing to their success.
When we think of symbiotic relationships, we often imagine animals like birds and crocodiles or insects and flowers. But did you know that even in the ocean’s depths, creatures rely on partnerships with bacteria for survival? Meet the blood-feeding marine invertebrates, fascinating creatures that face numerous challenges in their quest for sustenance.
Blood-feeding animals, whether on land or in the sea, are intriguing because of their ability to feed on a difficult-to-digest, toxic, and nutritionally deficient diet. Imagine trying to survive on such a meal! However, these creatures have evolved a remarkable strategy by forming symbiotic relationships with bacteria in their digestive systems.
Inside the digestive systems of blood-feeding marine invertebrates, bacteria play a critical role in breaking down and extracting nutrients from the blood of fish and sharks. Without the assistance of these internal bacteria, their dietary strategies would be virtually impossible. These microscopic partners enable the invertebrates to obtain vital nutrients and contribute to their overall health and survival.
But here’s the fascinating part: we know very little about how internal bacteria influence the immense success of these blood-feeding marine invertebrates. That’s where Dr. Shana Goffredi, a renowned expert in the field, comes in. For over 25 years, Dr. Goffredi has been braving the ocean’s depths to study cooperative partnerships between bacteria and marine invertebrates.
As a Professor of Biology at Occidental College, Dr. Goffredi is a true explorer. Her unwavering commitment to uncovering the unique diversity of life on Earth has led her to discover and describe some of the most iconic deep-sea animals. From giant deep-sea tubeworms to the fascinating yeti crab, her research has significantly contributed to our understanding of biodiversity on our planet.
Through molecular, imaging, and experimental approaches, Dr. Goffredi aims to unravel the presence and influence of internal bacteria in blood-feeding invertebrates. Her research sheds light on the fascinating world of symbiosis in the ocean’s depths. From studying animal organs and tissues to uncovering new metabolisms and evolutionary lineages, Dr. Goffredi’s work is at the forefront of deep-sea exploration.
It’s not just the scientific impact that makes Dr. Goffredi’s research important, but also the practical implications. Blood-feeding animals can act as vectors for pathogens, potentially transmitting diseases that impact humans and fish stocks. Understanding the symbiotic relationships and microbial dynamics within these invertebrates can lead to innovative disease prevention and control approaches.
Dr. Goffredi’s tireless efforts have garnered recognition and funding from the National Science Foundation. Her findings have been published in prestigious journals such as Frontiers in Microbiology, Environmental Microbiology, and Science. The knowledge she continues to uncover is essential in expanding our understanding of the intricate symbiotic partnerships that shape our planet.
In conclusion, the Discovery Lecture Series on Briny Bloodsuckers – Vampire Invertebrates and Symbiotic Partnerships reveals the extraordinary and often unknown world of blood-feeding marine invertebrates. Through the expertise of Dr. Shana Goffredi, we delve into the intricate relationships between these creatures and the internal bacteria that facilitate their survival. Let us embark on this journey of exploration deep into the ocean’s depths, where the most captivating secrets of nature reside.

Source Description
Symbiotic partnerships involving two or more species are widespread. We ca,n expect to find them in every environment, from rainforests to urban landscapes to the oceans. It is clear that microbes are supremely important to the success of most animals, including humans, and that many dietary strategies would not be possible were it not for intimately associated bacteria. Blood-feeding marine invertebrates are no exception in that they contend with numerous obstacles associated with feeding on the blood of fish and sharks – a difficult-to-break down, toxic, and nutritionally deficient diet. Bacteria in animal digestive systems play critical roles in the exchange of nutrients and digestion of food, thus contributing to the host’s health and survival. Yet, virtually nothing is known about the influence of internal bacteria on the immense success of blood-feeding marine invertebrates. Blood-feeding animals are important to study because of their potential symbiotic relationships with microbes and their ability to act as both vectors for pathogens and the harm they cause to fish stocks. This presentation will describe a series of molecular, imaging, and experimental approaches to examine whether internal bacteria are present in blood-feeding invertebrates and whether they positively influence the success of this unusual group of marine parasites.
Dr. Shana Goffredi is a Professor of Biology at Occidental College. She considers herself an explorer at heart and is committed to uncovering the unique diversity of life on Earth. For 25 years, she has been traveling to the deep ocean, using submersibles, to study cooperative partnerships between bacteria and marine invertebrates. Dr. Goffredi has been involved in discovering and describing some of the most iconic deep-sea animals to date, including giant deep-sea tubeworms and the yeti crab. These enigmatic symbioses have significantly contributed to biodiversity on our planet by generating new forms (ex., animal organs and tissues), new metabolisms, and even new evolutionary lineages. At Occidental College, she teaches Zoology, Microbial Diversity, and Symbiosis courses. Dr. Goffredi’s funding has come from the National Science Foundation; she has published in journals such as Frontiers in Microbiology, Environmental Microbiology and Science. Her B.S. is in Biology/Marine Science from the Univ. of San Diego, and her Ph.D. is in Ecology, Evolution, and Marine Biology from UC Santa Barbara.
