Black Long Spine Sea Urchin Diadema AntillarumThe Black Long Spine Sea Urchin, scientifically known as Diadema Antillarum, is a striking marine invertebrate found in the Caribbean Sea and the western Atlantic Ocean. This urchin is characterized by its distinctive long, black spines that can reach up to 30 cm in length, making it a visually captivating addition to any marine aquarium.The Black Long Spine Sea Urchin is an omnivorous species, feeding on a variety of algae, detritus, and small invertebrates. It plays a crucial role in maintaining the balance of coral reef ecosystems by controlling the growth of algae.When it comes to tank mates, the Black Long Spine Sea Urchin is generally peaceful and can be kept with a variety of other reef-safe fish and invertebrates, such as clownfish, gobies, and shrimp. However, caution should be exercised as its long spines can pose a risk to more delicate tank inhabitants.Regarding its aggression level, the Black Long Spine Sea Urchin is considered relatively docile, but it may become more defensive if it feels threatened or its territory is encroached upon. It is essential to provide ample space and hiding spots in the aquarium to minimize potential conflicts.For optimal care, the Black Long Spine Sea Urchin requires a well-established marine aquarium with stable water parameters. The recommended water temperature should be between 72-82°F (22-28°C), with a pH range of 8.1-8.4 and a specific gravity of 1.023-1.025. Regular water changes and efficient filtration are crucial to maintain the necessary water quality.Overall, the Black Long Spine Sea Urchin is a captivating and unique addition to a marine aquarium, but it requires experienced aquarists who can provide the appropriate environment and care to ensure its long-term health and well-being.

Definitely a tough toy
Color: Blue
This is one of the few toys my
Boxer/american bulldog mix hasn’t been able to tear apart. He loves chewing on it and I love that he doesn’t chew on stuff he shouldn’t.
I have such an issue with toys being torn apart the day I bring them home. I wish there was a safe way for it to have a squeaker since he loves squeakers but I don’t think that is possible.

Croc-sational
Color: Blue
My tough chewer is OBSESSED with Croc. Stands up well, small particles occasionally come off but this beats going thru 3 stuffies in an hour. Good value, easy to clean and great for our 91lb pitty

Good for a few weeks for large dogs
Color: Blue
It held up for a few weeks. The arms and tip of the tail were chewed off. Had to throw it away so my dogs wouldnt eat the parts that they chewed off. It kept them busy for a while.

Dog likes it, but is very hard material around smaller dogs when he is playing and running
Color: Blue
My 22lb dog loves this chew. We have owned it just for one day. He immediately loved it and he races through the house holding it in his mouth like a grand prize.
I have concerns to the hardness of the ends of it, the material is very hard, and the tail comes to an end shape that could hurt other pets in a multidog home if it hit or stuck in them. I have two smaller chihuahua dogs, one who has lost an eye so this is something to be careful about with other dogs running with this toy. This may not affect a one dog home. Best to observe the dog while playing with it around others.

Withstands very aggressive chewing
Color: Blue
We have a very active and aggressive chewer. Items identified for aggressive chewers are “Gone in 60 Seconds”. This toy is amazing. It has withstood Jake’s many attempts to destroy it and is one of his favorites! It is not hard like acrylic but is hard rubber with some give decreasing risk of fractured teeth. Best toy yet!!!
