These spines(脊柱)on their side and back can wound a person or animal that tries to get this fish the wrong way. There are over 2, 000 different kinds of catfish One of the tiniest catfish is called a madtom. The madtom has bright patterns and is only 0.05 meters long. It lives ...
Types of Mollusk: Snails, Bivalves, Squid, and More Types of Fungi: Mushrooms, Toadstools, Molds, and More List of Sea Animals A–Z Chemical Weathering: A Great Natural Force
Spine density was expressed as the number of spines per 10 mm. No attempt was made to correct for spines hidden beneath or above the dendritic segment; therefore the spine density values are likely to underestimate the actual density of the dendritic spines. Cresyl Violet staining Subjects were ...
Green Hawthorn: The green hawthorn (Crataegus viridis, zones 4 to 8), which is native to the southeastern U.S., has heights between 20 and 35 feet. This species has fewer spines than other species of hawthorn and is believed to have greater resistance to certain diseases. ...

Also known as the Golf Ball Cactus, it is covered in white to pale pink spines that create the lace look. It produces white and pink flowers with a darker line through the middle, surrounding dark yellow stamens. Despite the spikey cactus look, the lace effect and delicate blooms make an...
Squaliformes are an order comprised of 126 different shark species. Like Heterodontiformes, Squaliformes have spines on both their dorsal fins and between five and seven gill slits. Unlike their cousins, however,these sharks tend to stick to deep ocean water (below 400 meters) and live close ...
stress on screw-rod systems. Then, fresh frozen calf spines were selected as a model for subsequent measurements. Fitted with a specially designed test pedicle screw, L5–L6 vertebrae were selected to repeat and verify the results of the finite element analysis. With the aid of universal ...
"This finding is particularly interesting because the process of growing new synaptic spines when people learn things is completely analogous to the processes we observed in the cells we used for this experiment: growing axons and migrating during fetal development," DiCicco-Bloom said. "So even t...
