You asked for it so here it is: a FOTD on the sandtiger shark!
Sandtiger sharks go by many names including the ragged-tooth shark and the gray nurse shark. When unprovoked, these sharks are fairly docile, despite their frightening appearance.
Female sandtiger sharks give birth to two live pups, one from each of their two uteri. Because of the relatively small litter size, sandtiger shark populations have a particularly slow growth rate and it takes them a long time to recover from population decreases.
