Although they are frequently listed as carnivorous, consuming mostly crustaceans and mollusks [22], they are also known for consuming copious amounts (up to 62% of gut content mass) of seagrass in some populations [23], and for feeding at lower trophic levels than other closely related species [24].
Do dolphins eat sea grass?
Fish is often their preferred food, but they’ll also consume seaweed, shellfish, other invertebrates, or even rocks. While this resourceful nature works well for many species, it also puts them at risk for consuming plastic and other debris that collects in the water. Read on to learn more about what dolphins eat.

What would happen if seagrasses disappear?
As a result, seagrass meadow soil around the world has accumulated an estimated nine billion tons of carbon. As seagrass meadows disappear, that carbon is being released back into the ocean. Some of it may make its way into the atmosphere as heat-trapping carbon dioxide.
Are there any sharks that are not carnivores?

Aquaculture development, trawling, and boat damage can also harm coastal seagrass communities. In addition to these direct human activities, climate change, sea level rise, and increasing severity of tropical storms were seen as potential risks for seagrasses (Grech et al., 2012).

The likely primary cause of seagrass loss is reduction in water clarity, both from increased nutrient loading and increased turbidity. Run-off of nutrients and sediments from human activities on land has major impacts in the coastal regions where seagrasses thrive.
