Most of them do. the only ones that don't are nurse sharks, whale sharks, and horn sharks.
there is not an exact number of spots in a whale shark. It's also depending in how old is it. thanks a lot and i hope i answered your question.
Blue whales can live to be as old as 40 years old. They are able to reproduce around 7 years old, and have a new offspring every few years.
They both live up to 50-100 years old and have dorsal fins with there vertical tails
Most of the sharks are old- dating back to the dinosaurs or just before- and there's some ancestors of the whale just after the dinos.
The Killer whale is the top predator of the oceans, having no threats other then people when it reaches adulthood, however baby, old, and ill whales often fall prey to other predators such as sharks
very very often about 300 people are killed a year by sharks
Sharks can die from various factors such as predation, disease, environmental changes, or human activities like overfishing and pollution. Additionally, sharks have a limited lifespan, and when they reach old age, their bodies may weaken, making them more vulnerable to death.
It depends on what type of whal but usually they do not need there mother any more
James Whale is 59 years old (birthdate: May 13, 1951).
The longest whale song to ever be recorded lasted for 42 hours and 12 minutes (37 secons to be precise). I don't know where it was recorded though. Add me on moshi monsters- I am whaleloverxxx BTW i'm 13 because there has been some confusion on how old I a and should I be on moshi monsters if I'm over 16 or something like that.
You need to specify what the three year old is. Humans cannot reproduce at that age, but many other animals can.
