Q. Which of the following marine species can show biofluorescence?:
Select the correct answer from the codes given below:
All of the given species show biofluroescence.
- Corals: Corals make so much of one particular protein which causes them to be fluorescent. This composes 15% of the protein in corals. Corals could use biofluorescence as an attractant for microbeswith whom they have a symbiotic relationship — microbes have very good photoreceptors and can see different colours. So, this could be a great way to signal microbes to inhabit corals.
- Fishes: Fishes use biofluorescence as camouflage or to call to other fish with the same phenomena.
- Shark: The molecule causing fluorescence in sharks is an anti-microbial. So, nothing will ever grow on these sharks, even if they just sit at the bottom of the sea.
- Sea turtle: Biofluorescence has also been found in a sea turtle.
