Fishhook cactus facts for kids
The Fishhook cactus is a cool type of cactus known for its unique, hook-shaped spines. These spines look a bit like fishhooks, which is how they got their name! This name is used for many different cacti that have these special spines. They belong to several groups, or genera, of cacti like Mammillaria, Echinomastus, and Sclerocactus.
These cacti are usually small. They often grow up to about 6 to 7 inches (or 20 centimeters) tall. They have a shape similar to a barrel cactus. It's important not to mix them up with the fishhook barrel cactus (Ferocactus wislizenii). That one is a different type of cactus found in the Sonoran and Chihuahuan Desert areas. There are about 150 different kinds of cacti that are called "Fishhook cactus."
You can often find these interesting cacti growing in desert areas and rocky places. Great spots to see Mammillaria fishhook cacti include the Sonoran Desert, which is near the border between the U.S. and Mexico, and also Mesa Verde National Park.
