How fast do harbor porpoises swim?
Harbor porpoises swam freely in a tank at a swim speed ranging 0.5–4.2 m/s. Swimming during most dives was relatively slow with mean swim speed being 0.76–0.91 m/s. Oxygen consumption rate of the swimming harbor porpoise increased with swim speed according to a cubed function.
How much oxygen does a porpoise consume when it swims?
Oxygen consumption rate of the swimming harbor porpoise increased with swim speed according to a cubed function. The minimum cost of transport during underwater swimming in the harbor porpoise was 2.39–2.43 J/kg per m at an average swim speed of 1.3–1.5 m/s.
What whales do porpoises swim with?
They are known to associate with Pacific white-sided dolphins and short-finned pilot whales but have also been seen swimming alongside large whales. As rapid, social swimmers, Dall’s porpoises are also attracted to fast moving vessels and commonly bowride beside ships.
What is the fastest speed a fish can swim?
Sailfish (Maximum Speed 68 mph) These fish are definitely fast leapers and are likely one of the fastest fish at swimming short distances. The ? ReefQuest Centre for Shark Research describes speed trials in which a sailfish was clocked at a speed of 68 mph while leaping. Sailfish can grow to about 10 feet long.
What is the class of a porpoise?
Porpoises belong to the Phocoenidae family and the class Mammalia. There are seven subspecies of porpoises. These include the harbor porpoise, Burmeister’s porpoise, Dall’s porpoise, the narrow-ridged finless porpoise, the spectacled porpoise, the Indo-Pacific finless porpoise, and the vaquita – thought to be the most endangered marine mammal in the world.
How big do porpoises get?
However, as their name suggests, the finless species of porpoise do not have fins. Porpoises range from 4.7 to 7.7 feet in length and can weigh between 110 to 490 pounds. Females are usually larger than males.
How to tell if a porpoise is related to a dolphin?
? Porpoises are related to both dolphins and whales. To tell the difference between a porpoise and dolphin, look at the animal’s nose. A dolphin has a beak-like nose while a porpoise has a more rounded head and shorter nose.
What is the sound that a porpoise makes when it echoes back to its prey?
Echolocation happens when a porpoise makes a sound that bounces off its prey and echoes back to them. This allows a porpoise to detect the location of prey even when it’s swimming in the dark depths of the sea! Porpoises are social animals with one another and can travel in groups of 20.
What is the scientific name for a harbor porpoise?
The scientific name of a harbor porpoise is Phocoena phocoena. The word ‘Phocoena’ is Latin for ‘pig fish’. A porpoise is sometimes called a puffin’ pig because of the exhaling sound it makes when it reaches the surface of the water after a dive. Some scientists think the noise sounds like a sneeze!
How fast can a porpoise swim?
A porpoise can swim as fast as 34 mph!
Which is bigger, a dolphin or a porpoise?
For one, dolphins are larger than porpoises. A dolphin ’s body is slender and long while a porpoise has a body that is thicker and more stocky. Also, while porpoises have spade-shaped teeth, dolphins have teeth shaped like cones.
What is NOAA Fisheries?
NOAA Fisheries is investigating all aspects of acoustic communication and hearing in marine animals. In 2018, we updated our marine mammal acoustic technical guidance for assessing the effects of anthropogenic sound on marine mammal hearing.
What is the effect of underwater noise pollution on Dall’s porpoises?
Underwater noise pollution interrupts the normal behavior of Dall’s porpoises and interferes with their communication.
Why is it important to know the number of Dall’s porpoises in each population?
Determining the number of Dall’s porpoises in each population—and whether a stock is increasing or decreasing over time —helps resource managers assess the success of enacted conservation measures. Our scientists collect information and present these data in annual stock assessment reports.
How does sound pollution affect dalls?
Sound pollution threatens Dall’s porpoise populations by interrupting their normal behavior and driving them away from areas important to their survival. Increasing evidence suggests that exposure to intense underwater sound in some settings may cause some porpoises to strand and ultimately die.
How deep can a dall’s porpoise dive?
Dall’s porpoises can dive up to 1,640 feet to feed on small schooling fish (e.g., anchovies, herring, and hake), mid- and deep-water fish (e.g., lanternfish and smelts), cephalopods (e.g., squid and octopus), and occasionally crustaceans (e.g., crabs and shrimp).
How long do dalls live?
These cetaceans can live up to 22 years, but their lifespan is generally 15 to 20 years.
What is the color of a dall’s porpoise?
A special characteristic of Dall’s porpoises is their distinctive color pattern: a black body with a conspicuous white lateral patch on the left, right, and underside. They are often mistaken for baby killer whales, but unlike killer whales, their dorsal fins are triangle-shaped and they do not have eye patches or saddle patches.

Some speed trials describe a sailfish clocking in at 68 mph while leaping. Sailfish can grow to 10 feet long and, though slim, weigh up to 128 pounds. Their most noticeable characteristics are their large first dorsal fin, which resembles a sail, and their upper jaw, which is long and spear-like.
