Vaquita habitat is restricted to a small portion of the upper Gulf of California (also called the Sea of Cortez), making this the smallest range of any cetacean species. They live in shallow, turbid waters of less than 150 m (490 ft) depth.
The International Whaling Commission released its first ever extinction alert to raise awareness surrounding the decreasing vaquita porpoise population.
Toothed whales range in size from the 1.4 m (4 ft 7 in) and 54 kg (119 lb) vaquita to the 20 m (66 ft) and 100 t (98 long tons; 110 short tons) sperm whale. Several species of odontocetes exhibit sexual dimorphism, in that there are size or other morphological differences between females and males. They have streamlined bodies and two limbs ...
A vaquita swimming in the Gulf of California. Porpoises are highly affected by bycatch. Many porpoises, mainly the vaquita, are subject to great mortality due to gillnetting. Although it is the world's most endangered marine cetacean, the vaquita continues to be caught in small-mesh gillnet fisheries throughout much of its range.
The number of Mexico’s critically endangered vaquita marina porpoises sighted in the Gulf of California fell to between 6 and 8 this year, researchers said Tuesday. Last year, experts on a ...
Artiodactyls live on every major landmass and throughout the oceans and in a variety of habitats, including forests, grasslands, and deserts. They come in a wide array of body plans in contrasting shapes and sizes, ranging from the 38 cm (15 in) long and 2.5 kg (5.5 lb) royal antelope to the 27 m (89 ft) long and 120 ton blue whale.
Rarity rests on a specific species being represented by a small number of organisms worldwide, usually fewer than 10,000. However, a species having a very narrow endemic range or fragmented habitat also influences the concept. [2] [3] Almost 75% of known species can be classified as "rare". [4] Rare species are species with small populations.
Sea of Shadows is a 2019 documentary about environmental activists (Sea Shepherd), the Mexican Navy, marine scientists and undercover investigators trying to prevent the extinction of the vaquita, a species of porpoise and the smallest whale in the world, by pulling gillnets, doing research, and fighting back Mexican cartels and Chinese mafia who are destroying ocean habitats in their brutal ...
