Seeds begin to develop in about 2–4 weeks if fertilization occurred. [7] Female turtle grass fruits develop into green capsule about 20–25 mm in diameter and can include 1-6 small seeds. [ 17 ] [ 13 ] After about 8 weeks of growth, the fruit undergoes dehiscence (botany) , which releases neutrally buoyant seeds into the water column.
Unlike some other sea urchins, collector urchins graze continually, day and night. They graze near the substrate, and their diet includes algae, periphyton, and seagrass. [4] Most collector urchins feed on seagrass fronds; this has an ecological impact varying with the season and abundance of the urchins.
In the seagrass beds, the turtles feed on the seagrass by trimming only the top and leaving the roots of the plant. Through their feeding technique, the turtles help to improve the health and growth of the seagrass beds. The healthy seagrass beds that the turtles provide give habitat and feeding grounds for many species of fish and crustaceans.

The background image can be chosen from five different options and there are four tile sets, including traditional Mahjong tiles, variations with fuller coloring or larger print, and an alternative pastel tile set with an entirely ...
Few species were originally considered to feed directly on seagrass leaves (partly because of their low nutritional content), but scientific reviews and improved working methods have shown that seagrass herbivory is an important link in the food chain, feeding hundreds of species, including green turtles, dugongs, manatees, fish, geese, swans ...
The marbled parrotfish (Leptoscarus vaigiensis), also known as the seagrass parrotfish, is a species of parrotfish, the only known member of the genus Leptoscarus. It has a wide Indo-Pacific distribution and is also found in the southeastern Atlantic Ocean. It is a coastal species found in beds of sea grass and seaweed.
Seagrass is a marine angiosperm that possesses conductive tissue, shoot systems, rhizomes and flowers. [14] It has flat leaves up to 20 cm long, dark reddish-brown, with a few teeth on the margins. The fruits are spherical to egg-shaped, about 2 mm across. [10] [4] [15]
Zostera is a small genus of widely distributed seagrasses, commonly called marine eelgrass, or simply seagrass or eelgrass, and also known as seaweed by some fishers and recreational boaters including yacht captains.
