Absolutely love your blog. Thanks for doing this!
There are so many fascinating tail shapes of sharks! Why are there so many?
Thank you for your question!
The caudal fin of a shark varies between the shark species, in respect to their evolution for their own special habitat. Heterocercal caudal fin is where the top part of the tail is larger than the ventral portion (like the Tiger shark and Thresher shark). A homocercal caudal fin, like that of the great white or porbeagle, allows for great bursts of speed. And tails like of the Cookiecutter and Nurse allow slow movement.
Hi Ms. Marquez,
What different modes of reproduction do sharks have?
I'm studying sharks for a science project in November- you inspired me!
Thanks for being such a great shark advocate! If you need any help, feel free to look around Sarasota Fins or ask me questions!
As for your question, there are a few methods.
There is oviparity (egg-laying) and is common for about 40% of shark species. Viviparity is where embryos stay in the uterus for all development. The nourishment comes either the mother or yolk. When there is no connection between the mom and pup, but the embryo stays inside the uterus, this is called aplacental viviparity or ovoviviparity.
So what's the verdict: Can sharks see in color?
I know that you've been to a lot of places with sharks. So, what's it like to swim with sharks?
If you're scared of sharks, dive with them. See them in their natural habitat. And then see how scared you are afterwards.
