Cownose Ray

The cownose ray (Rhinoptera bonasus) is a species of ray. It gets it's name from the shape of it's head because it looks like a cow's nose. To find their prey, they will either flap there fins to stir up the sand, or they will move the sand around with their snouts. Once they have located there prey, they will rapidly flap their fins to reveal their prey. Cownose rays will migrate by the thousands from the Gulf of Mexico, and up the east side of the U.S.. Their natural predators include cobia and sharks. They are not commercially fished by people. However, the Virginia Sea Grant at VIMS is trying to persuade people to start eating cownose rays because a main part of their diet is oysters. But since cownose rays usually only have one pup at a time, it could cause a decrease in the population like the thylacines did. Cownose rays are commonly kept in touch tanks in aquariums. I don't think that I have ever been to a stingray touch tank where they did not have cownose rays.

Mandarin Dragonet


The mandarin dragonet (Synchiropus splendidus), is a tropical from the family Callionymidae. Mandarin dragonets go by many different names including mandarin goby and mandarin fish. They usually live in small groups in the wild. Mandarin dragonets produce a thick mucus that covers them and is toxic to whatever might try to eat it. Mandarin dragonets will dull in color when they are going to rest at night. Mandarin dragonets are popular in marine pet stores, despite the fact that they are difficult to feed because they eat amphipods and other small invertebrates.

Beach finds

 There finds were found a few weeks ago, but I have had a very busy schedule and have not had much time to post on my blog. The two top photos are the stuff which I kept, and the last photo is the stuff that I either recycled or threw away. The best find that I found that day was the shark tooth necklace in the first picture. It was far from where most people stay when they go to Lido.

Lightning Whelks



Lightning whelks (Busycon contrarium), are gastropods like other whelks and snails. They are called lightning whelks because of the jagged lines on the juvenile's shells. The shells in the picture are small ones. There have been lightning whelks recorded at 15"! Lightning whelks are sinistral or "left handed", compared to most whelks which are dextral or "right handed". The lightning whelk is also the state shell of Texas.

Olive Snails

Olive Snail Shells
Olive snails (Oliva sayana), are gastropods like other snails. The ones in the pictures are lettered olives, there are other varieties too that I do not have pictures of like the netted olive (Oliva reticularis), and several smaller varieties. Lettered olives can grow up to 2 1/2 inches in length. The second olive in the picture is fossilized.

Colorful Moonsnail


The colorful moonsnail (Naticarius canrena), are gastropods. They are uncommon at the beaches that I have been to (that is why I only have one).
Moonsnails prey on  buried bivalves. Their foot is about ten times the size of their shell and is light colored with brown streaks running down it.

Rubber Snakes to Silver Spoons (Another Trip to Lido)

Common Sand Toys
Yesterday we were coming back from a volunteer interview, and we decided to take a trip to the beach. We have not been to the beach recently because of the winter tourists, and because it was so cold the last month. I have not been cleaning up the beach for a while and I have been wondering what could have happened to the beach during our absence. It was a mess! Trash was everywhere! So I began to clean up. I started putting trash in a soda cup that I have been drinking out of only a few minutes earlier.
Strings and Other Long Stretchy Things
Stranger Things to Find on Lido Beach
 But that soon overflowed. Then I found a green bucket which was abandoned, so I started using that. But that too started to fill up quicker than I expected. Then I found a yellow bucket without a handle, and a second bucket made everything much easier because I could separate the keep from the trash. I keep the things that I can either reuse or make something awesome out of. Some of the normal keep things I found were pony tails, plastic sand toys, and a neat ball that I'm sure my sisters will enjoy playing with. The weirder things I found were a feathery flower, two silver spoons, and a rubber snake.
Speaking of rubber snakes, there once was a dolphin who ate a rubber snake that someone discarded. It is really important that trash and other things like toys, do not get left on the beach. (If any of these are yours, and you are near Lido beach, I can give it back to you.)
