Hatchlings are fed amphipods or mysid shrimp. Some are then fed baby clams and small crabs. (The clams can be placed in a small shell or shallow bowl.) Young octos may be given ghost shrimp, which are easier for them to catch than shore shrimp but are not suitable for long-term use.
What is the lifespan of a bimaculoides?
O. bimaculoides has a natural lifespan of 1 to 1 ½ years. The approach of the end is signaled by egg laying in the female or senility in the male. In the ocean, the female encounters a male who gives her a packet of sperm, which she keeps until she is ready to lay eggs.
How can you tell a bimac from an octopus?
One can identify the species by the circular blue eyespots on each side of its head. Bimacs usually live to be about two years old. They are closely related to Verrill's two-spot octopus ( Octopus bimaculatus ).
How do you take care of a bimac fish at home?
Bimacs like a sandy substrate and caves of rock or several lengths of PVC pipe to hide in. Bimacs tolerate a wide temperature range, ideally around 65-72 degrees F. (18 – 22 degrees C) in the home aquarium. They don't need a lot of light – a 30-watt daylight spectrum lamp for 8-10 hours/day should be enough.

Blue-ringed-octopuses hunt during the day. They eat small crabs, hermit crabs, shrimp, and occasionally small fishes: however, they are primarily crab-eaters.
What happens if you touch a blue-ringed octopus?
The octopi's salivary glands produce the venom, and the bacteria gets dispersed through their beak. TTX can paralyze a human in minutes. Due to this paralysis, your body wouldn't be able to get enough oxygen, and death from a blue-ringed octopus would occur.
How do you take care of an octopus?
Octopus is a less maintenance animal; it doesn't require much care. The best circumstances for your octopus pet can result from maintaining their water tank regularly. Most of them tend to become inactive if their natural habitat fades away. Hence it's important to keep their natural habitat intact and well-nourished.
Do octopus bite you?
Most of the time they're yellow or sand-colored, but bright blue rings appear on their body when they're about to strike. They'll strike only if they feel threatened. If a blue-ringed octopus does bite you, you need to get medical treatment immediately because their bites can be fatal in a short amount of time.

Abstract
The performance of Octopus bimaculoides juveniles from coastal areas of Baja California (Mexico) and reared in captivity was evaluated using Artemia salina as food source in three different treatments: Artemia enriched with either AlgaMac or Spirulina maxima and without enrichment.
1. Introduction
In recent years the global demand for cephalopods, especially Octopus sp., has resulted in increasing interest in culturing these species. Several studies have established that cephalopods adapt relatively easily to captivity, have a high growth rate and high feed conversion ratios ( Nixon, 1969, Mangold, 1983, Navarro and Villanueva, 2003 ).
2. Materials and methods
A. salina was cultured at 27 °C as follows: after hydrating for 1 h, the cysts with seawater were washed in a sodium hypochlorite solution, and then transferred and kept in an 80-L column with constant air bubbling and fed on a mixture of live Tetraselmis suecica and Isochrysis galbana until adult size (15 days old).
3. Results
During the experimental period (0–20 days), no significant difference in mortalities was observed. The Spirulina- enriched (SE) treatment showed the highest mortality (27.78 ± 1.5%), followed by the AlgaMac-enriched (AE) treatment (16.67 ± 1.0%), while no mortality was observed in the treatment without enrichment (WE).
4. Discussion
In the present study O. bimaculoides juveniles were able to grow and develop using Artemia as the sole food source, showing higher growth rates than those previously reported for other octopus species fed Artemia ( Iglesias et al., 1996) or other food sources ( Moxica et al., 2002 ).

Range
O. bimaculoides can be found in coastal waters from the intertidal down to at least 20 m (65 ft) in the eastern Pacific along mid- and southern- California and the western side of the Baja California Peninsula in Mexico.
Habitat
This species of octopus is found in subtidal to a depth of 20 m (65 ft). It prefers rocky reefs or debris for hiding. It tolerates a wide temperature range 15-26 °C (60-80 °F), though it prefers 18-22 °C (65-72 °F).
Description
Octopus bimaculoides reaches a mantle size of 17.5 cm (7 inches) with arms to 58 cm (23 inches). Not usually heavily textured, it has several common colors, such as grey with yellow splotches, and uses highly developed crypsis (camouflage or color-changing to match the environment).
Distinctive features
This octopus gets its name from the false eye spot under each real eye. The eye spots are known as ocelli. In O. bimaculoides, the ocellus is an iridescent blue, chain-link circle set in a circle of black.
Lifespan
These octopuses live one to two years. The end is signaled by egg-laying in the female and senescence in both males and females.
Diet
Adults feed on primarily small crabs and snails, but can have a very varied clams, mussels, , and diet appears to vary with location, season, and sex. Hatchlings feed on amphipods or mysid shrimp.
Nervous System
In recent years new technology, such as genome sequencing, has provided new information on the large amounts of clustered protocadherins (PCDH) in Octopus bimaculoides. The octopus was found to have 168 PCDH genes, about 120 clustered and 50 non-clustered PCDH.
What is the diet of O. bimaculatus?
Diet. O. bimaculatus is known to prey on crustaceans, snails, chitons, limpets, and bivalves. Studies have observed the predator-prey interactions between the O. bimaculatus and the Californian Scorpionfish ( Sc o rpaena guttata) in aquariums.
Why are O. bimaculatus and O. bimaculoides different?
O. bimaculatus is often confused with Octopus bimaculoides due to the similarity in looks, however they are two different species. They both have these two distinctive black and blue ocelli beneath the eyes and above the arms, however there are a few key differences in their features to tell the two species apart.
What is the difference between octopus and bimaculatus?
Additionally, octopus bimaculatus is generally the larger of the two species.
How long does O. bimaculatus live?
O. bimaculatus lives about 12–18 months. Young are planktonic for one to several months before settling on the ground. However, in captivity, O. bimaculatus has been observed to live up to 2 years.
Do octopus have chromatophores?
Similar to other octopus species, O. bimaculatus has skin covered in chromatophores. During the post-larval stage, there are only a few chromatophores and they are called the "founder chromatophores.". However, as the octopus matures, more chromatophores form and cover the skin.
