What special adaptations do manatees have?
Manatees breathe air just like humans, so they hold their breath. Their special adaptation is that they can close their nostrils so that water does not get into their lungs, just like we hold our nose when we dive underwater. On the slide, one picture shows the manatee’s nostrils open, and the other shows them closed.
What adaptations do West Indian manatees have?
Adaptations
- Since West Indian manatees feed on grass growing on the sea floor, their snouts are bent downwards so as to facilitate the grasping their food.
- They have sensitive whiskers all over their body which are known as vibrissae.
- Their forelimbs are evolved into flippers to help them to swim.
How do manatees respond to the environment?
below the surface of the water. All marine mammals have special physiological adaptations for diving. These adaptations enable a manatee to conserve oxygen while under water. Manatees, like other marine mammals, have a slower heart rate while diving.
What special adaptations do manatees have that allow them to stay under water longer than the average land dwelling mammal?
Marine mammals have a number of adaptations that allow them to stay under water longer than the average land-dwelling mammal. The manatee’s lungs lie along its backbone instead of along its rib cage as found in most mammals. The lungs are long, wide, and thin.
How do manatees survive predators?
Their only real protection strategy is to remain in very shallow water. This way, if they are attacked, it is less likely that the predator can drag them under the water for longer than the 15 minutes that the manatee can survive without breathing. Manatees protect themselves by avoiding trouble.
What human activities are threatening manatee survival?
Manatees continue to face many threats, including collisions with boats, habitat loss and degradation, fishing gear entanglement, human harassment, exposure to red tide and other harmful algal blooms, and climate change. The greatest long-term threat is the loss of warm water habitat.
How do manatees protect themselves against sharks?
Do manatees feel pain?
As far as manatees go, it is still unclear to what extent they feel pain. The fact that they are an endangered species makes is difficult to study them.
How are manatees affected by humans?
Accidentally or intentionally introduced into rivers, bays or oceans, human-generated trash becomes marine debris, which can be a big problem for aquatic wildlife and habitats. Entanglement in and ingestion of marine debris by marine life can be fatal, and manatees are no exception.
What are some fun facts about manatees?
12 Surprising Facts About Manatees

Do manatees breathe air?
Manatees never leave the water but, like all marine mammals, they must breathe air at the surface. A resting manatee can remain submerged for up to 15 minutes, but while swimming, it must surface every three or four minutes.
