Dive beneath the ocean waves and explore the unique and diverse relationships found on a coral reef.
How do species interact on a coral reef? Dive beneath the ocean waves and explore the many unique symbiotic relationships found in this diverse ecosystem.
In addition to showcasing live footage from a unique ecosystem, each of the three videos in the Exploring Ecosystems series features an opportunity for students to actively participate in a problem-solving scenario based on an ongoing research project of an Academy scientist.
As you watch the video, be prepared to pause at key points to participate fully! Explore a coral reef in the Philippines with biologist Luiz Rocha with Bubbletip Sea Anemone (Entacmaea quadricolor) and their Maroon Clownfish (Premnas biaculeatus) guests, Whitetip Reef Sharks (Triaenodon obesus), Wrasse (Labridae), and Blenny (Blennioidei) in their symbiotic and parasitic relationships, as well as Whale Shark (Rhincodon typus) and Cleaner Fish as we look at abiotic and biotic relationships.
The Coral Reef Symbiosis video investigates the following questions:
How do species interact on a coral reef?
What are the effects of abiotic and biotic interactions?
How do these interactions influence patterns of distribution and abundance within this ecosystem as a whole?
Check for Understanding
Describe two concrete examples of mutualistic relationships found on a coral reef, being sure to describe what each organism gets out of the deal.
Key Scientific Terms
abiotic: non-living
commensalism: a type of symbiosis where one organism benefits and the other is not affected in a positive or a negative way
ecosystem: the community of different species in a particular geographic area and all of their interactions with each other and the physical environment
mutualism: a type of symbiosis where both organisms benefit
parasitism: a type of symbiosis where one organism (the parasite) benefits and the other (the host) is harmed
symbiosis: a long-term relationship or interaction between individuals from two different types of species; the symbiotic relationship has a positive, negative or neutral impact on the participants
