How do you identify a whale?
What you should note when identifying a whale
- body length.
- presence of a dorsal fin.
- size and position of the dorsal fin.
- shape and size of flippers.
- shape of the head and general body shape.
- presence of a beak.
- shape of the blow.
- body colour and patterns.
How can you tell a gray whale from a humpback whale?
Humpback whales measure up to 49 feet long and 90,000 pounds in weight. Just like their name indicates, gray whales are gray in color. They are large and measure up to 49 feet in length and 90,000 pounds in weight. Although gray whales don’t have dorsal fins, they have wide and short pad-like pectoral flippers.
How do you tag a whale?
Use Suction Scientists will place these suction cups, which support a kit that holds a camera and a small suite of sensors and transmitters, on the end of a pole more than 20 feet in length, allowing them to get close enough to tap a whale on the back. Whale tags can be attached for 24-hour periods with suction cups.
How do you identify a whale’s tail?
A whale’s tail ranges from all black to all white to any combination in between. Researchers compare the overall color patterns, the scars, and the serrations along the trailing edge to differentiate one tail from another. Identifying individuals is a crucial component of all wildlife research.
How can you tell a whale from a spout?
Notice the size and shape of the water blow. If you notice a water spout, watch the general area for the whale to return to the surface again. Gray whales and right whales have 2 blowholes, so they produce a heart-shaped spout. Sperm whales spray water diagonally forward, unlike other species.
How do you identify a GREY whale?
Gray whales, for example, have a double blow-hole, and their spouts are heart-shaped. Humpback whales have a tall, column-shaped blow. And orcas typically have a bushy-shaped blow. If you see something that looks like a blow, keep watching!
What’s the difference between grey and humpback whales?
Gray whales have a streamlined body, and unlike humpback whales, no dorsal fin, which is a good way to differentiate gray whales from humpback whales. They do however have a prominent dorsal hump about two thirds of the way down their back, followed by a series of six to 12 knobs extending to the tail stock.
How long do whale tags last?
Tags remained on the blue whales an average of 22 days and on the fin whales about 14 days. It’s unclear why the tags came off the fin whales more quickly, but it could have to do with their movement and faster speed in the water, Irvine said.
Why do people tag whales?
When you’re a small boat, in ice-filled seas, chasing whales, it’s kind of a unique experience. By tagging the whales, we get a position from GPS and we can track them and create computer simulations of the behavior of the exact movement of the whales.
How can you tell a blue whale from a fin whale?
Fin whales are large, but very sleek and streamlined. From above, the head is more pointed than that of the blue whale, and the dorsal fin tends to be taller, more falcate, and set farther forward on the tail stock than in the blue whale. The dorsal fin rises at a shallow angle from the animal’s back.
How do you identify cetacean?
An easy way to identify cetaceans to species is by looking at the shape of their dorsal fin. Porpoises have triangular dorsal fins, dolphins have curved fins, and large whales dorsal fins in all shapes and sizes, or even none at all!
How do you identify a humpback whale?
Humpback whales are identified by the underside and trailing edge of their tail flukes; each one is different just like a fingerprint. In British Columbia humpbacks are given a letter as part of their identification to categorize their fluke based on color.
What whale has dots?
The head of a humpback whale is about 2.5m in size and has a symmetrical distribution of what look like bubbles on it. These are tubercles. Each one of these tubercles is about the size of your fist and encases one or two hairs called vibrissae.
What whale has white dots?
gray whales
Those patchy white spots you see on gray whales are barnacles. Grays carry heavy loads of these freeloaders. The barnacles are just along for the ride. They don’t harm the whales or feed on the whales, like true parasites do.
What is a group of whales called?
A group of whales is commonly referred to as a pod, among other names. Like humans, whales form groups and families through friendship or for other biological reasons. A group such as this may also be called a school or gam.
How does a whale tag work?
The message is being sent by a satellite tag attached to the whale. Each time the whale surfaces for air, the tag sends a signal to GPS satellites orbiting the earth. Using the changing latitude and longitude data, whale researchers can plot the course of an individual animal along its migration route.
Are humpback whales tagged?
Satellite tagging of humpback whales has provided a breeding range analyses that offers the first-ever insight on the distribution of humpbacks and the coastal space they use for breeding and migration, particularly for mother/calf pairs.
Why is tag used on ocean animals?
To find out where ocean animals go and the routes they take to get there, scientists attach electronic tags to them. Those tags collect data on temperature, depth, and location, then transmit their data via satellite.
How can you tell the difference between a blue whale and a humpback whale?
They are visually different. The blue whale is larger, greyer, and more streamlined. Humpbacks are noted for a distinctive hump on their back and a bluer coloring. They also have a small dorsal fin and long pectoral fins.
