Bandtail Scorpionfish (Scorpaenopsis neglecta) by Samantha Craven

Scorpionfish are ambush predators. Their exceptional camouflage allows them to wait in hiding until prey swim past, and which point they lunge forward and basically inhale them!

In 1998, Rishi Sowa built his first artificial island using 250,000 plastic bottles to keep it afloat, and today he lives on Spiral Island II, a smaller island that he built using 100,000 bottles. The island features a house, beaches, ponds and even a solar-powered waterfall.

Even more ambitious than Sowa’s island is architect Ramon Knoester’s plan to build Recycled Island, a floating island the size of Hawaii made entirely of recycled plastic. The island would be completely self-sufficient, supporting its own agriculture and getting its power from solar and wave energy. When it’s complete, Knoester hopes the island will house half a million residents who can enjoy the artificial island’s seaweed harvest and compost toilets.

This graceful Spotted Eagle Ray (Aetobatus narinari) was trusting enough to let me get just close enough to catch a profile shot. There were two eagle rays feeding in this sandy bay. They descend onto the sandy bottom and catch crustaceans and fish hiding in the sand below.

Baby mola mola, so shiny and cute. Via

karlayst: Mola by sailroue59  - A baby Ocean Sunfish, Mola mola.
We still don’t fully understand the reproductive practices of Mola mola but suggested spawning sites include North Atlantic, South Atlantic, North Pacific, South Pacific, and Indian Oceans (narrows it down, doesn’t it?!). 
Females can produce a whopping 300 million eggs at a time, more than any other known vertebrate.The eggs are externally fertilized in the water column. Newly hatched sunfish larvae are only 2.5 mm (0.098 in) long. They grow to become fry, and those which survive grow many millions of times their original size before reaching adult proportions.
Adults, with their enormous size and tough skin have few predators (that include sea lions, orcas and some sharks), but the babies are prone to predation from bluefin tuna and mahi mahi. 
Sunfish fry, with large pectoral fins, a tail fin and body spines uncharacteristic of adult sunfish, resemble miniature pufferfish, their close relatives.Young sunfish school for protection, but this behaviour is abandoned as they grow.

Estuary Seahorse (Hippocampus kuda) by Samantha Craven

Greeks and Romans believed the seahorse was an attribute of the sea god Poseidon/Neptune, and the seahorse was considered a symbol of strength and power. Europeans believed that the seahorse carried the souls of deceased sailors to the underworld - giving them safe passage and protection until they met their soul’s destination.

Back to modern times - this species is classified as Vulnerable by the IUCN and all seahorse species are protected from international trade by CITES.

Jawless Fish - Class Agnatha

They feed by suction (parasitic and scavenging), have cylindrical and elongated bodies, have no true fins or scales, have one nostril, and have a cartilaginous skeleton. Pictured is the mouth of a lamprey eel, a migratory agnathan (they live in both fresh and salt water).

Bluntnose Six Gill Shark (Hexanchus griseus)

… often simply called the “Cow Shark”, is a large shark, growing to more than 5.4 m (18 ft) in length. Although sluggish in nature, the bluntnose sixgill shark is capable of attaining high speeds for chasing and catching its prey. Because of the bluntnose sixgill shark’s large and diverse range they have a wide variety of prey items.

The bluntnose sixgill shark is a member of the Hexanchidae family. Many of its relatives are extinct. The living species that are closest genetically include the dogfish, the Greenland shark, as well as other six- and sevengilled sharks. There are more closely related relatives in the fossil record than living species. Some of the shark’s relatives date back to 200 million years ago. This shark is a notable species due to both its primitive and current physical characteristics.

This species typically inhabits depths greater than 90 m (300 ft), and has been recorded as deep as 1,875 m (6,150 ft). Like many deep-sea creatures, the bluntnose sixgill shark is known to undertake nightly vertical migrations (travelling surfaceward at night, returning to the depths before dawn)…
