It is the smallest known Cetacean (whale, dolphin, or porpoise) alive today, reaching lengths of only 4-5 feet (1.2-1.5 m) and weights of not much more than 100 pounds (45 kg). All our clothing have been named after an animal which is about to be extinct due to human actions. The Vaquita is neither a keystone or umbrella species it is not super important to its ecosystem and it does not protect other species.
Vaquitas are predatory and eat a variety of Gulf of California fishes, squids, and crustaceans.
Under the right circumstances the health of the ecosystem might be linked in large measure to the vaquita. Interrelationships within a food web can be so intricate that a chain of disruptive events can occur when one ecosystem component changes. Among the Cetaceans, Vaquitas reach sexual maturity relatively quickly and begin reproducing at age 3-6 years old.
Be the first to answer this question. Habitat alteration and marine pollution are also potential threats to its survival, and the International Union for Conservation of Nature includes the vaquita on its list of critically endangered species – it is very highly vulnerable to extinction. Trophic Levels. It is the smallest known Cetacean (whale, dolphin, or porpoise) alive today, reaching lengths of only 4-5 feet (1.2-1.5 m) and weights of not much more than 100 pounds (45 kg). We have already protected nearly 4 million square miles of ocean and innumerable sea life - but there is still more to be done. Lifespan is also low, with individuals likely living no longer than approximately 25 years. Water Cycle: The ocean plays an important part in the water cycle. They are extremely shy and are therefore very difficult for scientists to study in their natural habitat.
The Vaquita is a small harbor porpoise native to a very small area in the extreme northern part of the Gulf of California, Mexico. Much of our knowledge of vaquitas is a result of their being captured as bycatch in local net fisheries. Food Chain.
The ocean related components in the water cycle are evaporation from the ocean and land surfaces, the transport of water vapor by the atmosphere, precipitation onto the ocean and land surfaces, the net atmospheric transport of water from land areas to ocean, and the return flow of fresh water from the land back into the ocean.

Vaquita is the only porpoise, living in warm waters such as these of the Gulf of California: porpoises inhabit cooler waters, typically lower than 20 degrees Celsius. Groups from intermediate TL had higher values of structural indexes, indicating their function in the control of flows throughout the network. Button Text <-CLICK IT!!! Be the first to answer! 0 1 2.
Another distinctive feature of Vaquita is its ability of tolerating large annual fluctuations in temperature, which is also uncommon in porpoises.
97% of the world's water comes from the ocean.
