Spinyhead blenny or Acanthemblemaria Spinosa, is a small fish, native to the tropical western Atlantic Ocean and Caribbean Sea. They are a molted black, white and red, over theit body. On top the head, are hair like appendages. Spinyhead blennies grow to about 1.1 inches or 2.8 cm.
If you are looking to spot them, looking on coral heads in abandon worm holes are the ideal places to search. When you find one, you find many more, as they most times live in a colony. Any abandoned holes that they fit into, immediately becomes their home and territory.
When it comes to territory, most times they fight for a hole. Many of the spinyhead blennies prefer the hole at the highest point, as this increases the chance of getting a meal drifting by. What do they eat? From crustaceans to also planktonic particles. These types of blennies also can also sift each eye independent from each other.
How cool is that! This is so they can see what is around them at all times. In a pre prepared nesting site, the female spinyhead then lays her eggs in that nest. The male spinyhead blenny look for the best hole, which in turn attracts a female. Characteristically deep, in the selection of the hole, the female will lay her eggs in it, and in turn the male spinyhead blenny protects it after he has fertilized the eggs.
Alot of the spinyhead blenny’s disputes surround the occupation of holes and getting the best one, to attract a female. The male spinyhead defend their hole because the bigger the hole the more dominant the blenny. When threaten, the blenny aggressively swing their head and open their mouth wide.
