Pineapple fish have very unusual feeding habits. They have thin, tiny teeth and feed at night with a small green patch on their lower jaw that is covered in small bacteria that glow in the dark. This glow attracts small shrimp. This patch turns from green to red as they get older.
The horseshoe crab is a living fossil. It has been on Earth some 220 million years, longer than dinosaurs. And it survives today almost identical to its ancient ancestors. Horseshoe crabs are more closely related to spiders, ticks and scorpions than they are to true crabs.
The females taking care of their fry are called maternal mouthbrooders because the female immediately picks up the fertilized eggs and holds them in her mouth for about three weeks while the little ones hatch and grow a bit. During this time, the female will not eat in order to give the next generation a head start in life.
Barrier reefs help to protect lagoons and other shallow waters. It is essentially a coral reef running parallel to the shore but separated from it by a channel of deep water. A barrier reef is usually pierced by several channels that give access to the lagoon and the island or continent beyond it.
Not much is known about this cichlid due to it being endemic to Lake Malawi, meaning they are only found in this particular lake. There are a total of 12 genera of very active and aggressive personalities in this group. Regardless of the drastically different personalities in a group, a single group won't swim much more than about 3 feet away from the particular rock island they have designated as their home.
Ocean Sunfish lay more eggs than any other vertebrate animal...roughly 300,000,000, and they are voracious predators feeding mostly on jellyfish. In German, they are called “swimming heads”, but they may or may not be plankton. Despite its massive size, the sunfish has been classified for years as a type of plankton,
“While the fish in this photo appears to be sitting there allowing me to take his photo it was quite the contrary. He came up at me from the sandy bottom with such intent and speed that I couldn't believe I managed to get him in the frame, let alone having him and is grumpy face in focus!”
Not much information is found on Gibberfish due to their rarity. The Gibberichthyidae, also known as gibberfishes, are a small family of deep seastephanoberyciform fish containing a single genus and two species.
Tiger Tail Sea Cucumbers are the largest sea cucumber in the Western Atlantic. They feed on algae and detritus. Juveniles often mimic sea slugs by crawling around on the bottom slowly filtering sand through their tentacles to gather food.
